India's Overpopulation

India, with a population of over 1.3 billion , is facing the consequences of overpopulation. The rapid population growth has put a strain on resources, resulting in issues such as food and water shortages, as well as strain on energy resources. The water crisis in India, where over half of the population is facing high to extreme water stress, is a prime example of how overpopulation can affect the availability of resources.

China's One-Child Policy

China, with a population of over 1.4 billion, has implemented a one-child policy to control its population growth. The policy, which was in effect from 1979 to 2015, aimed to slow down the population growth and improve the standard of living. While the policy did lead to a decrease in population growth, it also had negative consequences such as a gender imbalance and an aging population.

Singapore's Aging Population

Singapore, with a population of around 5.7 million, has one of the lowest fertility rates in the world. The low fertility rate, coupled with an increasing life expectancy, has led to an aging population. This has put a strain on the country's healthcare and pension systems, as well as the workforce. The government has implemented various measures, such as incentives for couples to have more children and encouraging immigration, to address the issue of an aging population.

Population growth is a global phenomenon that affects not only the resources and environment, but also the economy and society as a whole. It's important for governments to implement policies to address the challenges posed by population growth and ensure sustainable development. This can include investing in infrastructure, implementing measures to reduce pollution and waste, and encouraging family planning and education programs. Additionally, it's important to find sustainable solutions to the challenges posed by population growth in order to ensure a future where everyone has access to the resources they need to live a healthy and fulfilling life.

Essay on Population for Students and Children

500+ words essay on population.

Population refers to the total number of beings living in a particular area. Population helps us get an estimate of the number of beings and how to act accordingly. For instance, if we know the particular population of a city, we can estimate the number of resources it needs. Similarly, we can do the same for animals. If we look at the human population, we see how it is becoming a cause of concern. In particular, the third world countries suffer the most from population explosion. As it is the resources there are limited and the ever-increasing population just makes it worse. On the other hand, there is a problem of low population in many regions.

India population crisis

India faces a major population crisis due to the growing population. If we were to estimate, we can say that almost 17% of the population of the world lives in India alone. India ranks second in the list of most populated countries.

Furthermore, India is also one of the countries with low literacy rates. This factor contributes largely to the population explosion in India. It is usually seen that the illiterate and poor classes have a greater number of children. This happens mainly because they do not have sufficient knowledge about birth control methods . In addition, more people in a family are equals to more helping hands. This means they have better chances of earning.

Moreover, we also see how these classes practice early marriage. This makes it one of the major reasons for a greater population. People marry off their young daughters to men way older than them for money or to get free from their responsibility. The young girl bears children from an early age and continues to do so for a long time.

As India is facing a shortage of resources, the population crisis just adds on to the problem. It makes it quite hard for every citizen to get an equal share of resources. This makes the poor poorer and the rich richer.

Impact of Population Explosion

Subsequently, pollution levels are on the rise because of the population explosion. As more and more humans are purchasing automobiles, our air is getting polluted. Moreover, the increased need calls for faster rates of industrialization. These industries pollute our water and lands, harming and degrading our quality of life.

In addition, our climate is also facing drastic changes because of human activities. Climate change is real and it is happening. It is impacting our lives very harmfully and must be monitored now. Global warming which occurs mostly due to activities by humans is one of the factors for climate change.

Humans are still able to withstand the climate and adapt accordingly, but animals cannot. This is why wildlife is getting extinct as well.

In other words, man always thinks about his well-being and becomes selfish. He overlooks the impact he is creating on the surroundings. If the population rates continue to rise at this rate, then we won’t be able to survive for long. As with this population growth comes harmful consequences. Therefore, we must take measures to control the population.

Tips for writing an essay on population

• Make an outline. Once you do your research, create a well-detailed plan where you include all the essential points and ideas for each paragraph of your paper. You can use the example from the section below and build on it with the information you have found.  
• Research carefully. Try using Google Scholar to search for articles and books on the topic if you have hard times determining which sources are credible.  
• Don’t fake your references or just copy information. Nowadays, there are various tools for checking works for plagiarism. Therefore, do not put your academic reputation at risk – use real sources and your own words when describing what the author was writing about.
• Mind your language. Of course, an essay is not a scientific article for a reputable journal, but you still need to be very careful with the word choice. Contractions or slang would not be appropriate here.
• Provide specific examples and numbers where applicable. For instance, essay writing on population explosion would require you to indicate where, when, and how many people were born in certain time periods and why it happened.
• Proofread your writing. This will help you to avoid submitting a work full of mistakes, which will inevitably lower your mark.

Essay outline

• Introduction.

Start with a hook phrase, which can be a question, a quote, or just an interesting fact. After that, write a few sentences explaining why your topic is important and necessary to research. The main point of an essay on population should be clearly stated in the last sentence of the paper – a thesis statement. Give a brief overview of the points you are going to discuss but do not go into the details – you will be able to do it in the body of the work.

Depending on the word limit set for the assignment, the body of your paper might be divided into a few sections with distinct headings. Each section or paragraph should start with the introduction of the idea you are going to discuss. Next, you will have to provide some factual information to support it, and explain your own opinion if applicable. In the end, it would be necessary to sum up what you have discussed and transition into the next paragraph.

• Population essay conclusion.

In the final paragraph, restate the thesis and the main ideas that were reviewed in the body of the paper. You cannot introduce any new facts in the conclusion – only synthesize what has already been discussed. Finish your essay by proving that you have accomplished the purpose of writing the paper or leave the reader with some idea to think about further.

Population research paper topics

• Research paper about homelessness population
• Aging population research paper
• Religion and overpopulation
• Human population growth research paper
• Birth control and women’s human rights
• The impact of overpopulation on the wildlife
• India population crisis
• The impact of overpopulation on the environment
• Bangladesh population crisis
• Population, migration, and urbanization
• Global warming and overpopulation: Where is the link?
• The issue of food and water shortage
• Statistics of population changes research paper
• The effects of population growth on the economy

Writing a research paper

• Choose a narrow topic. It is rather hard to write a research paper about population in general, as the topic is really vast. Instead, you may concentrate on some population issues, trends, or other more specific topics, which can be studied thoroughly.
• Be careful with citations. In your research paper, you will need to include and cite a lot of information. Learn how to do it according to the style you stick to and cite all factual data taken from other sources.
• Check a few good population research paper examples. If it is hard for you to visualize how your research paper should look like, find a few sample works. Pay attention to how the text is outlined, what information is cited, how transitions are used, and how the info is presented in general. Try to find research paper examples about population control, overpopulation crisis, shortage of resources, and other related topics to understand what points might work for your own paper.
• Develop a strong thesis statement. It should be short, to-the-point, and consistent. You have to summarize your main claim in one or two sentences in such a way that it will be clear and interesting for your audience.
• Avoid filler phrases. “In conclusion,” “needless to say,” and all the other parenthetic words do not bring any value to your writing. Instead, try to come up with meaningful transitions to move from one paragraph to another one smoothly.

Research paper outline

• Introduction
• Methodology
• Literature review
• Results/Findings

You may also be asked to add an abstract before the intro to give your readers a quick overview of the paper. Depending on the length of the text, it might be necessary to add a table of contents to guide your audience on where to find certain information. If there are some figures that you wanted to include in the paper but they take too much space, you can refer to them in the text but insert them into the appendices section after the reference page.

Research questions about population

Here are some of the research paper questions about population that you may choose to answer in your paper:

• What are the major negative consequences of overpopulation?
• Why some countries are overpopulated while others are underpopulated?
• How fast is the population increasing today compared to in the past?
• What factors influence current population trends?
• What may the population trends be in 50 years?
• Are we on the verge of food and water shortage?
• Is population growth still an issue?
• How many people can Earth support?
• Why should we be concerned about current population growth rates?
• Is religion an obstacle to population stabilization?

Facts for a research paper or essay on population

• In general, more than 107 billion people were born in the history of humanity. Thus, 6.5% of all people born in the history of humankind live on Earth today.
• In 2009, for the first time in history, an urban population was equal to a rural one amounting to 3.4 billion people. It is expected that in the future, an increasing part of the world population will be represented by citizens (that is, the urban population will continue to grow faster than the world population as a whole), which is confirmed by the latest data.
• In 2010, about 60% of the world’s population lived in Asia, 15.5% - in Africa, and 10.4% - in Europe. In 2050, according to the UN forecast, more than half of the world’s population will live in Asia, 25% in Africa, 8.2% in Latin America, 7.4% in Europe, and 4.7% in North America.
• The largest state in terms of population is China. After 2025, India is likely to become a leader. Until 1991, USSR had the third-largest population. After its disintegration, the US took its place. Indonesia and Brazil occupy the fourth and fifth places. Pakistan, Bangladesh, Nigeria, and Russia occupy the sixth, seventh, eighth, and ninth places, respectively.
• As the UN report indicates, by the end of this century, the world’s population will be more than two times higher in comparison with 2011 and will reach 15 billion people.
• The current population of the planet has doubled since the 1960s. This process is caused by the improvement of the quality of medical care and medical products as well as high fertility in the countries of Africa, Asia, and Latin America. In addition, a certain role was played by the reduction of infant mortality and the increase in life expectancy on all continents of the planet.
• Some experts question the figure of 15 billion inhabitants by the year 2100 proposed by the UN. They are convinced that the population will not reach such a catastrophic scale if appropriate measures are taken.
• The author of the first essay on population was a popular economist Thomas Robert Malthus. His main work, An Essay on the Principle of Population, played a remarkable role in the development of economic science and demography.
• In the mid-60s of the 20th century, humanity first paid attention to the problem of overpopulation and the depletion of resources. The community of the world’s largest businessmen, politicians, and public figures, united by the idea of ​​ preserving the natural environment on Earth have created a so-called Club of Rome. This initiated a large-scale research to find ways to curb the crisis.

Environmental issues

While writing an essay on the ecological effects of increased population, you may describe the current state of things:

• The situation in the field of renewable resources deteriorates. Scientists warn that very soon, we will experience a water, wood, fish shortage, as well as reduced soil fertility.
• Waste products accumulate and pollute the environment.
• More investment, energy, materials, and labor costs are required to eliminate the negative consequences of using resources, e.g., for sewage treatment, irrigation control, air purification, etc.
• A significant part of the capital, raw materials, energy resources, and labor costs is spent on solving the tasks of the defense industry.
• Investments in human resources decline, and the situation with education and healthcare deteriorates.
• The balance between the use of raw materials, energy resources, and the process of environmental pollution is disturbed.

Problem of population aging

• According to the UN, during 1994-2014, the number of people over 60 years has doubled. In 2014, the number of older adults in the world exceeded the number of children under the age of five.
• Now, in 15 EU countries, above 15% of citizens are at the age of 65 years and higher. The youngest country is Ireland (11.5%), and the oldest one is Sweden (17.5%). However, during the coming decades, the gap will decrease. The elderly group will be joined by generations born during the baby boom period (1946-1964).
• Compared to Western European countries, the United States is a younger state: there are less than 13% of people over 65 years old.
• The causes of population aging are ambiguous. On the one hand, there is a decline in the birth rate, which leads to a smaller number of children and young people, and on the other hand, there is an increase in life expectancy.
• From 1960 to 1990, the number of people of age above 80 years has grown in the EU countries from 5 to 12 million people, that is, by 140%.
• Medical care for the elderly involves additional funding, expanding the network of medical, gerontological institutions, and qualitative restructuring of the health care system.
• The employment of the elderly population and provision of working places for young seniors are required. It is also important to maintain an active life position of the elderly, involve them in public life, and fight against loneliness.

The world population explosion: causes, backgrounds and projections for the future

J. van bavel.

Centre for Sociological Research / Family & Population Studies (FaPOS), Faculty of Social Sciences, University of Leuven, Parkstraat 45 bus 3601, 3000 Leuven, Belgium.

At the beginning of the nineteenth century, the total world population crossed the threshold of 1 billion people for the first time in the history of the homo sapiens sapiens. Since then, growth rates have been increasing exponentially, reaching staggeringly high peaks in the 20th century and slowing down a bit thereafter. Total world population reached 7 billion just after 2010 and is expected to count 9 billion by 2045. This paper first charts the differences in population growth between the world regions. Next, the mechanisms behind unprecedented population growth are explained and plausible scenarios for future developments are discussed. Crucial for the long term trend will be the rate of decline of the number of births per woman, called total fertility. Improvements in education, reproductive health and child survival will be needed to speed up the decline of total fertility, particularly in Africa. But in all scenarios, world population will continue to grow for some time due to population momentum. Finally, the paper outlines the debate about the consequences of the population explosion, involving poverty and food security, the impact on the natural environment, and migration flows.

Key words: Fertility, family planning, world population, population growth, demographic transition, urbanization, population momentum, population projections.

Introduction

In the year 1900, Belgium and the Philippines had more or less the same population, around 7 million people. By the year 2000, the population of the Western European monarchy had grown to 10 million citizens, while the South East Asian republic at the turn of the century already counted 76 million citizens. The population of Belgium has since then exceeded 11 million citizens, but it is unlikely that this number will rise to 12 million by the year 2050. The population of the Philippines on the other hand will continue to grow to a staggering 127 million citizens by 2050, according to the demographic projections of the United Nations (UN 2013).

The demographic growth rate of the Philippines around the turn of the century (2% a year) has already created enormous challenges and is clearly unsustainable in the long term: such growth implies a doubling of the population every 35 years as a consequence of which there would be 152 million people by 2035, 304 million by 2070, and so on. Nobody expects such a growth to actually occur. This contribution will discuss the more realistic scenarios for the future.

Even the rather modest Belgian demographic growth rate around the turn of this century (0.46%) is not sustainable in the long term. In any case, it exceeds by far the average growth rate of the human species (homo sapiens sapiens) that arose in Africa some 200.000 years ago. Today, earth is inhabited by some 7 billion people. To achieve this number in 200.000 years, the average yearly growth rate over this term should have been around 0.011% annually (so 11 extra human beings per 1.000 human beings already living on earth). The current Belgian growth rate would imply that our country would have grown to 7 billion in less than 1500 years.

The point of this story is that the current growth numbers are historically very exceptional and untenable in the long term. The demographic growth rates are indeed on the decline worldwide and this paper will attempt to explain some of the mechanisms behind that process. That doesn’t change the fact, however, that the growth remains extraordinarily high and the decline in some regions very slow. This is especially the case in Sub Saharan Africa. In absolute numbers, the world population will continue to grow anyway for quite some time as a result of demographic inertia. This too will be further clarified in this paper.

The evolution of the world population in numbers

In order to be sustainable, the long term growth rate of the population should not differ much from 0%. That is because a growth rate exceeding 0% has exponential implications. In simple terms: if a combination of birth and growth figures only appears to cause a modest population growth initially, then this seems to imply an explosive growth in the longer term.

Thomas R. Malthus already acquired this point of view by the end of the 18th century. In his famous “Essay on the Principle of Population” (first edition in 1789), Malthus argues justly that in time the growth of the population will inevitably slow down, either by an increase of the death rate or by a decrease of the birth rate. On a local scale, migration also plays an important role.

It is no coincidence that Malthus’ essay appeared in England at the end of the 18th century. After all, the population there had started to grow at a historically unseen rate. More specifically the proletariat had grown immensely and that worried the intellectuals and the elite. Year after year, new demographic growth records were recorded.

At the beginning of the 19th century, the number of 1 billion people was exceeded for the first time in history. Subsequently growth accelerated and the number of 2 billion people was already surpassed around 1920. By 1960, another billion had been added, in 40 instead of 120 years time. And it continued to go even faster: 4 billion by 1974, 5 billion by 1987, 6 billion by 1999 and 7 billion in 2011 ( Fig. 1 ).

This will certainly not stop at the current 7 billion. According to the most recent projections by the United Nations, the number of 8 billion will probably be exceeded by 2025, and around 2045 there will be more than 9 billion people 1 . The further one looks into the future, the more uncertain these figures become, and with demography on a world scale one must always take into account a margin of error of a couple of tens of millions. But according to all plausible scenarios, the number of 9 billion will be exceeded by 2050.

Demographic growth was and is not equally distributed around the globe. The population explosion first occurred on a small scale and with a relatively moderate intensity in Europe and America, more or less between 1750 and 1950. From 1950 on, a much more substantial and intensive population explosion started to take place in Asia, Latin America and Africa ( Fig. 2 ). Asia already represented over 55% of the world population in 1950 with its 1.4 billion citizens and by the year 2010 this had increased to 4.2 billion people or 60%. Of those people, more than 1.3 billion live in China and 1.2 billion in India, together accounting for more than one third of the world population.

In the future, the proportion of Asia will come down and that of Africa will increase. Africa was populated by some 230 million people around 1950, or 9% of the world population. In 2010 there were already more than 1 billion Africans or 15% of the world population. According to UN projections, Africa will continue to grow at a spectacular rate up to 2.2 billion inhabitants in 2050 or 24% of the world population. The proportion of Europe, on the other hand, is evolving in the opposite direction: from 22% of the world population in 1950, over 11% in 2010 to an expected mere 8% in 2050. The population of Latin America has grown and is growing rapidly in absolute terms, but because of the strong growth in Asia and especially Africa, the relative proportion of the Latin American population is hardly increasing (at most from 6 to 8%). The proportion of the population in North America, finally, has decreased slightly from 7 to 5% of the world population.

What these figures mainly come down to in practice is that the population size in especially the poor countries is increasing at an unprecedented rate. At the moment, more than 5.7 billion people, or more than 80% of humanity, are living in what the UN categorise as a developing country. By 2050, that number would – according to the projections – have increased to 8 billion people or 86% of the world population. Within this group of developing countries, the group of least developed countries, the poorest countries so to speak, is growing strongly: from 830 million now, up to an expected 1.7 billion in 2050. This comprises very poor countries such as Somalia, Sudan, Liberia, Niger or Togo in Africa; Afghanistan, Bangladesh or Myanmar in Asia; and Haiti in the Caribbean.

The growth of the world population goes hand in hand with global urbanisation: while around the year 1950 less than 30% of people lived in the cities, this proportion has increased to more than 50%. It is expected that this proportion will continue to grow to two thirds around 2050. Latin America is the most urbanised continent (84%), closely followed by North America (82%) and at a distance by Europe (73%). The population density has increased intensely especially in the poorest countries: from 9 people per square km in 1950 to 40 people per square km in 2010 (an increase by 330%) in the poorest countries, while this figure in the rich countries increased from 15 to 23 people per square km (a 50% growth). In Belgium, population density is 358 people per square km and in the Netherlands 400 people per square km; in Rwanda this number is 411, in the Palestinian regions 666 and in Bangladesh an astonishing 1050.

Although the world population will continue to grow in absolute figures for some time – a following paragraph will explain why – the growth rate in percentages in all large world regions is decreasing. In the richer countries, the yearly growth rate has already declined to below 0.3%. On a global scale, the yearly growth rate of more than 2% at the peak around 1965 decreased to around 1% now. A further decline to less than 0.5% by 2050 is expected. In the world’s poorest countries, the demographic growth is still largest: at present around 2.2%. For these countries, a considerable decrease is expected, but the projected growth rate would not fall below 1.5% before 2050. This means, as mentioned above, a massive growth of the population in absolute figures in the world’s poorest countries.

Causes of the explosion: the demographic transition

The cause of, first, the acceleration and, then, the deceleration in population growth is the modern demographic transition: an increasingly growing group of countries has experienced a transition from relatively high to low birth and death rates, or is still in the process of experiencing this. It is this transition that is causing the modern population explosion. Figure 3 is a schematic and strongly simplified representation of the modern demographic transition.

In Europe, the modern demographic transition started to take place in the middle of the 18th century. Until then, years of extremely high death rates were quite frequent. Extremely high crisis mortality could be the consequence of epidemic diseases or failed harvests and famine, or a combination of both. As a consequence of better hygiene and a better transportation infrastructure (for one, the canals and roads constructed by Austria in the 18th century), amongst other reasons, crisis mortality became less and less frequent. Later on in the 19th century, child survival began to improve. Vaccination against smallpox for example led to an eradication of the disease, with the last European smallpox pandemic dating from 1871. This way, not only the years of crisis mortality became less frequent, but also the average death rate decreased, from an average 30 deaths per 1000 inhabitants in the beginning of the 19th century to around 15 deaths per 1000 citizens by the beginning of the 20th century. In the meantime, the birth rate however stayed at its previous, high level of 30-35 births per 1000 inhabitants.

The death rate went down but the birth rate still didn’t: this caused a large growth in population. It was only near the end of the nineteenth century (a bit earlier in some countries, later in others) that married couples in large numbers started to reduce their number of children. By the middle of the 20th century, the middle class ideal of a two children household had gained enormous popularity and influence. The reaction by the Church, for example in the encyclical Humanae Vitae (1968), came much too late to bring this evolution to a halt.

As a consequence of widespread family planning – made even easier in the sixties by modern hormonal contraceptives – the birth rate started declining as well and the population tended back towards zero growth. Nowadays the end of this transition process has been more than achieved in all European countries, because the fertility has been below replacement level for several decades (the replacement level is the fertility level that would in the long term lead to a birth rate identical to the death rate, if there would be no migration) 2 .

That the population explosion in the developing countries since the second half of the 20th century was so much more intense and massive, is a consequence of the fact that in those countries, the process of demographic transition occurred to a much more extreme extent and on a much larger scale. On the one hand, mortality decreased faster than in Europe. After all, in Europe the decline in mortality was the result of a gradual understanding of the importance of hygiene and afterwards the development of new medical insights. These insights of course already existed at the start of the demographic transitions in Asian, Latin American and African regions, whereby the life expectancy in these regions could grow faster. On the other hand, the total fertility – the average number of children per woman – at the start of the transition was a lot higher in many poor regions than it initially was in Europe. For South Korea, Brasil and the Congo, for example, the total fertility rate shortly after the Second World War (at the start of their demographic transition) is estimated to be 6 children per woman. In Belgium this number was close to 4.5 children per woman by the middle of the nineteenth century. In some developing regions, the fertility and birth rate decreased moderately to very fast, but in other regions this decline took off at an exceptionally sluggish pace – this will be further explained later on. As a consequence of these combinations of factors, in most of these countries the population explosion was much larger than it had been in most European countries.

Scenarios for the future

Nonetheless, the process of demographic transition has reached its second phase in almost all countries in the world, namely the phase of declining fertility and birth rates. In a lot of Asian and Latin American countries, the entire transition has taken place and the fertility level is around or below the replacement level. South Korea for example is currently at 1.2 children per woman and is one of the countries with the lowest fertility levels in the world. In Iran and Brasil the fertility level is currently more or less equal to Belgium’s, that is 1.8 to 1.9 children per woman.

Crucial to the future evolution of the population is the further evolution of the birth rate. Scenarios for the future evolution of the size and age of the population differ according to the hypotheses concerning the further evolution of the birth rate. The evolution of the birth rate is in turn dependent on two things: the further evolution of the total fertility rate (the average number of children per woman) in the first place and population momentum in the second. The latter is a concept I will later on discuss in more detail. The role of the population momentum is usually overlooked in the popular debates, but is of utmost importance in understanding the further evolution of the world population. Population momentum is the reason why we are as good as certain that the world population will continue to grow for a while. The other factor, the evolution of the fertility rate, is much more uncertain but of critical importance in the long term. The rate at which the further growth of the world population can be slowed down is primarily dependent on the extent to which the fertility rates will continue to decline. I will further elaborate on this notion in the next paragraph. After that, I will clarify the notion of population momentum.

Declining fertility

Fertility is going down everywhere in the world, but it’s going down particularly slowly in Africa. A further decline remains uncertain there. Figure 4 shows the evolution per world region between 1950 and 2010, plus the projected evolution until 2050. The numbers before 2010 illustrate three things. First of all, on all continents there is a decline going on. Secondly, this decline is not equal everywhere. And thirdly: the differences between the continents remain large in some cases. Asia and Latin America have seen a similar decline in fertility: from 5.9 children per woman in 1950 to 2.5 at the start of the 21st century. Europe and North America had already gone through the largest part of their demographic transition by the 1950’s. Their fertility level has been below replacement levels for years. Africa has indeed seen a global decrease of fertility, but the average number of children is still at an alarmingly high level: the fertility merely decreased from 6.7 to 5.1 children per woman.

These continental averages hide a huge underlying diversity in fertility paths. Figure 5 attempts to illustrate this for a number of countries. Firstly let us consider two African countries: the Congo and Niger. As was often the case in Europe in the 19th century, fertility was first on the rise before it started declining. In the Congo this decrease was more extensive, from around 6 children in 1980 to 4 children per woman today, and a further decline to just below three is expected in the next thirty years. Niger is the country where the fertility level remains highest: from 7 it first rose to an average of just below 8 children per woman in the middle of the 1980’s, before decreasing to just above 6.5 today. For the next decades a decline to 4 children per woman is expected. But that is not at all certain: it is dependent on circumstances that will be further explained in a moment. The demographic transition is after all not a law of nature but the result of human actions and human institutions.

Around 1950, Pakistan and Iran had more or less the same fertility level as Niger, but both countries have seen a considerable decline in the meantime. In Pakistan the level decreased slowly to the current level of 3 children per woman. In Iran the fertility decreased more abruptly, faster and deeper to below the replacement level – Iran today has one of the lowest fertility levels in the world, and a further decline is expected. The Iranian Revolution of 1978 played a crucial role in the history of Iran (Abassi-Shavazi et al., 2009): it brought better education and health care, two essential ingredients for birth control.

Brasil was also one of the countries with very high fertility in the 1950’s – higher than the Congo, for example. The decrease started earlier than in Iran but happened more gradually. Today both countries have the same total fertility, below the replacement level.

Child mortality, education and family planning

Which factors cause the average number of children to go down? The literature concerning explanations for the decrease in fertility is vast and complex, but two factors emerge as crucial in this process: education and child survival.

Considering child survival first: countries combining intensive birth control with very high child mortality are simply non-existent. The statistical association between the level of child mortality and fertility is very tight and strong: in countries with high child mortality, fertility is high, and vice versa. This statistical correlation is very strong because the causal relation goes in both directions; with quick succession of children and therefore a lot of children to take care for, the chances of survival for the infants are lower than in those families with only a limited number of children to take care of – this is a fortiori the case where infrastructure for health care is lacking. A high fertility level thus contributes to a high child mortality. And in the other direction: where survival chances of children improve, the fertility will go down because even those households with a lower number of children have increasing confidence in having descendants in the long term.

It is crucial to understand that the decline in child mortality in the demographic transition always precedes the decline in fertility. Men, women and families cannot be convinced of the benefits of birth control if they don’t have confidence in the survival chances of their children. Better health care is therefore essential, and a lack of good health care is one of the reasons for a persistently high fertility in a country like Niger.

Education is another factor that can cause a decline in fertility. This is probably the most important factor, not just because education is an important humanitarian goal in itself (apart from the demographic effects), but also because with education one can kill two birds with one stone: education causes more birth control but also better child survival (recently clearly demonstrated by Smith-Greenaway (2013), which in its turn will lead to better birth control. The statistical correlation between level of education and level of fertility is therefore very strong.

Firstly, education enhances the motivation for birth control: if parents invest in the education of their children, they will have fewer children, as has been demonstrated. Secondly, education promotes a more forward-looking lifestyle: it will lead people to think on a somewhat longer term, to think about tomorrow, next week and next month, instead of living for the day. This attitude is necessary for effective birth control. Thirdly, education also increases the potential for effective contraception, because birth control doesn’t just happen, especially not when efficient family planning facilities are not or hardly accessible or when there are opposing cultural or family values.

The influence of education on birth control has been demonstrated in a vast number of studies (James et al., 2012). It starts with primary education, but an even larger effect can be attained by investment in secondary education (Cohen, 2008). In a country like Niger, for example, women who didn’t finish primary school have on average 7.8 children. Women who did finish primary school have on average 6.7 children, while women who finished secondary school “only” have 4.6 children ( Fig. 6 ). The fertility of Niger would be a lot lower if more women could benefit from education. The tragedy of that country is that too many people fall in the category of those without a degree of primary school, with all its demographic consequences.

One achieves with education therefore a plural beneficial demographic effect on top of the important objective of human emancipation in itself. All this is of course not always true but depends on which form of “education”; I assume that we’re talking about education that teaches people the knowledge and skills to better take control of their own destiny.

It is one thing to get people motivated to practice birth control but obtaining actual effective contraception is quite another matter. Information concerning the efficient use of contraceptives and increasing the accessibility and affordability of contraceptives can therefore play an important role. There are an estimated 215 million women who would want to have contraception but don’t have the means (UNFPA, 2011). Investments in services to help with family planning are absolutely necessary and could already have great results in this group of women. But it’s no use to put the cart before the horse: if there is no intention to practice birth control, propaganda for and accessibility of contraception will hardly have any effect, as was demonstrated in the past. In Europe the lion’s share of the decline in fertility was realized with traditional methods, before the introduction of hormonal contraception in the sixties. There is often a problem of lack of motivation for birth control on the one hand, as a result of high child mortality and low schooling rates, and a lack of power in women who may be motivated to limit fertility but are confronted with male resistance on the other (Blanc, 2011; Do and Kurimoto, 2012). Empowerment of women is therefore essential, and education can play an important role in that process as well.

Population momentum

Even if all the people would suddenly practice birth control much more than is currently considered possible, the world population would still continue to grow for a while. This is the consequence of population momentum, a notion that refers to the phenomenon of demographic inertia, comparable to the phenomenon of momentum and inertia in the field of physics. Demographic growth is like a moving train: even when you turn off the engine, the movement will continue for a little while.

The power and direction of population momentum is dependent on the age structure of the population. Compare the population pyramids of Egypt and Germany ( Fig. 7 ). The one for Egypt has a pyramidal shape indeed, but the one for Germany looks more like an onion. As a consequence of high birth rates in the previous decades, the largest groups of Egyptians are to be found below the age of forty; the younger, the more voluminous the generation. Even if the current and future generations of Egyptians would limit their fertility strongly (as is indeed the case), the birth rate in Egypt would still continue to rise for quite some time, just because year after year more and more potential mothers and fathers reach the fertile ages. Egypt therefore clearly has a growth momentum.

Germany on the other hand has a negative or shrinking momentum: even if the younger generations of Germans would have a larger num ber of children than the generation of their own parents, the birth rate in Germany would still continue to decrease because fewer and fewer potential mothers and fathers reach the fertile ages.

The population momentum on a global scale is positive: even if fertility would decrease overnight to the replacement level, the world population would continue to grow with 40% (from 7 billion to 9.8 billion). Only the rich countries have a shrinking momentum, that is -3%. For Europe the momentum is -7%. The population momentum for the poorest countries in the world is +44%, that of Sub Saharan Africa +46% (Espenshade et al., 2011).

Consequences of the population explosion

The concerns about the consequences of population explosion started in the sixties. Milestone publications were the 1968 book The Population bomb by biologist Paul Ehrlich, the report of the Club of Rome from 1972 (The Limits to Growth) and the first World Population Plan of Action of the UN in 1974 among others.

In the world population debate, the general concerns involve mainly three interconnected consequences of the population explosion: 1) the growing poverty in the world and famine; 2) the exhaustion and pollution of natural resources essential to human survival; and 3) the migration pressure from the poor South to the rich North (Van Bavel, 2004).

Poverty and famine

The Malthusian line of thought continues to leave an important mark on the debate regarding the association between population growth and poverty: Malthus saw an excessive population growth as an important cause of poverty and famine. Rightfully this Malthusian vision has been criticized a lot. One must after all take the reverse causal relation into account as well: poverty and the related social circumstances (like a lack of education and good health care for children) contribute to high population growth as well.

Concerning famine: the production of food has grown faster since 1960 than the world population has, so nowadays the amount of food produced per person exceeds that which existed before the population explosion (Lam, 2011). The problem of famine isn’t as much an insufficient food production as it is a lack of fair distribution (and a lack of sustainable production, but that’s another issue). Often regions with famine have ecological conditions permitting sufficient production of food, provided the necessary investments in human resources and technology are made. The most important cause of famine is therefore not the population explosion. Famine is primarily a consequence of unequal distribution of food, which in turn is caused by social-economic inequality, lack of democracy and (civil) war.

Poverty and famine usually have mainly political and institutional causes, not demographic ones. The Malthusian vision, that sees the population explosion as the root of all evil, therefore has to be corrected ( Fig. 8 ). Rapid population growth can indeed hinder economical development and can thus pave the way for poverty. But this is only part of the story. As mentioned, poverty is also an underlying cause of rapid population growth. Social factors are at the base of both poverty and population growth. It’s those social factors that require our intervention: via investments in education and (reproductive) health care.

Impact on the environment

The impact of the population explosion on the environment is unquestionably high, but the size of the population represents only one aspect of this. In this regard it can be useful to keep in mind the simple I=PAT scheme: the ecological footprint or impact on the environment (I) can be regarded as the product of the size of the population (P), the prosperity or consumption level (A for affluence) and the technology used (T). The relationship between each of these factors is more complex than the I=PAT scheme suggests, but in any case the footprint I of a population of 1000 people is for example dependent on how many of those people drive a car instead of a bike, and of the emission per car of the vehicle fleet concerned.

The ecological footprint of the world population has increased tremendously the past decades and the growth of the world population has obviously played an important role in this. The other factors in the I=PAT scheme have however played a relatively bigger role than the demographic factor P. The considerable increase in the Chinese ecological footprint of the past decades for example, is more a consequence of the increased consumption of meat than of population growth (Peters et al., 2007; Liu et al., 2008). The carbon dioxide emission of China grew by 82% between 1990 and 2003, while the population only increased by 11% in that same period. A similar story exists for India: the population grew by less than 23% between 1990 and 2003, while the emission of carbon dioxide increased by more than 83% (Chakravarty et al., 2009). The consumption of water and meat in the world is increasing more rapidly than the population 3 . The consumption of water per person is for example threefold higher in the US than in China (Hoekstra and Chapagain, 2007). The African continent has at present the same number of inhabitants as Europe and North America together, over 1 billion. But the total ecological footprint of Europeans and Americans is many times higher than that of Africans (Ewing et al., 2010). Less than 18% of the world population is responsible for over 50% of the global carbon dioxide emission (Chakravarty et al., 2009).

If we are therefore concerned about the impact of the world population on the environment, we can do something about it immediately by tackling our own overconsumption: it’s something we can control and it has an immediate effect. In contrast, we know of the population growth that it will continue for some time anyhow, even if people in poor countries would practice much more birth control than we consider possible at present.

The population explosion has created an increasing migration pressure from the South to the North – and there is also important migration within and between countries in the South. But here as well the message is: the main responsibility doesn’t lie with the population growth but with economic inequality. The primary motive for migration was and is economic disparity: people migrate from regions with no or badly paid labour and a low standard of living to other regions, where one hopes to find work and a higher standard of living (Massey et al., 1993; Hooghe et al., 2008; IMO, 2013). Given the permanent population growth and economical inequality, a further increasing migration pressure is to be expected, irrespective of the national policies adopted.

It is sometimes expected that economic growth and increasing incomes in the South will slow down the migration pressure, but that remains to be seen. After all, it isn’t usually the poorest citizens in developing countries that migrate to rich countries. It is rather the affluent middle class in poor countries that have the means to send their sons and daughters to the North – an investment that can raise a lot of money via remittances to the families in the country of origin (IMO, 2013). There is after all a considerable cost attached to migration, in terms of money and human capital. Not everyone can bear those costs: to migrate you need brains, guts and money. With growing economic development in poor countries, an initial increase in migration pressure from those countries would be expected; the association between social-economic development and emigration is not linearly negative but follows the shape of a J turned upside down: more emigration at the start of economic development and a decline in emigration only with further development (De Haas, 2007).

7 Billion and counting… What is to be done?

A world population that needed some millennia before reaching the number of 1 billion people, but then added some billions more after 1920 in less than a century: the social, cultural, economic and ecological consequences of such an evolution are so complex that they can lead to fear and indifference at the same time. What kind of constructive reaction is possible and productive in view of such an enormous issue?

First of all: we need to invest in education and health care in Africa and elsewhere, not just as a humanitarian target per se but also because it will encourage the spread of birth control. Secondly, we need to encourage and support the empowerment of women, not just via education but also via services for reproductive health. This has triple desirable results for demographics: it will lead to more and more effective birth control, which in itself has a positive effect on the survival of children, which in turn again facilitates birth control.

Thirdly: because of the positive population momentum, the world population will certainly continue to grow in absolute figures, even though the yearly growth rate in percentages is already on the decline for several years. The biggest contribution we could make therefore, with an immediate favourable impact for ourselves and the rest of the world, is to change our consumption pattern and deal with the structural overconsumption of the world’s richest countries.

(1) Unless otherwise specified, all figures in this paragraph are based on the United Nations World Population Prospects, the 2012 Revision, http://esa.un.org/wpp/ . Concerning projections for the future, I reported the results of the Medium Variant. Apart from this variant, there are also high and low variants (those relying on scenarios implying respectively an extremely high and extremely low growth of the population) and a variant in which the fertility rates are fixed at the current levels. It is expected that the actual number will be somewhere between the highest and lowest variant and will be closest to the medium variant. That’s why I only report this latter value.

(2) In demography, the term «fertility» refers to the actual number of live births per women. By contrast, the term fecundity refers to reproductive capacity (irrespective of actual childbearing), see Habbema et al. (2004).

Essay on Overpopulation in 500 Words

• Updated on  
• Dec 28, 2023

Essay on Overpopulation: Today, there are a total of 8.1 billion people in the world. This is a result of overpopulation and studies suggest that in the next 25 years, this number will reach 10 billion. This is overpopulation or overabundance, where our environment cannot offer resources to such large amounts of people. Overpopulation is not limited to humans only. It can be of any species living in a particular habitat. 

India, China, and the USA are the three most populated countries in the world, which account for a total of 40% of the global population. Population plays a major role in a country’s development. However, if there is overpopulation, it will hamper developmental activities and there will be fewer resources available. This will eventually lead to higher food prices, making survival difficult for everyone.

Causes of Overpopulation

There are various causes of overpopulation, such as lack of education, high birth rates, primitive medical facilities, illiteracy, lack of employment opportunities, etc. Most of these factors are prevalent in developing and underdeveloped countries. 

High birth rates contribute significantly to overpopulation. Factors such as lack of access to family planning, cultural norms, and a high infant mortality rate can encourage families to have more children.

Lack of education and poverty lead to higher population growth. People belonging to communities where education is limited, are not aware of or have access to family planning methods.

In many places, cultural and religious beliefs influence reproductive choices. Some families have several children, which is part of their social norm or is encouraged by religious teachings.

Another major cause of overpopulation is migration. People move to areas with better economic prospects, leading to population density issues in those regions.

Consequences of Overpopulation

In one way or another, all the problems the world is facing today are related to overpopulation. Say it war, overuse of resources, slow developmental activities, carbon emission, global warming, etc. 

Natural resources are depleting at a faster rate than ever. As the population increases, the demand for food and energy resources also increases. Overpopulation contributes to climate change, loss of biodiversity, and other environmental issues. 

As humans, we need houses, which are established by cutting down forests and other natural resources. This results in a loss of biodiversity. Rapid urbanization causes problems such as inadequate housing, insufficient infrastructure, traffic congestion, and increased pollution in urban areas. 

A rapidly growing population can outstrip job opportunities, resulting in high levels of unemployment. This can lead to social unrest and economic instability.

How to Deal With Overpopulation

Educating people about the causes and effects of overpopulation is one of the best ways to deal with overpopulation. Studies show that people who have access to proper medical and healthcare facilities have better family planning measures. 

Promoting and educating women and girls about reproduction is very important. Educated women tend to have fewer children and this will make them socially and economically more empowered. Encouraging women to participate in the workforce and decision-making processes can be another way to deal with overpopulation. 

Offering job opportunities and promoting green sustainable development will allow people to understand the effects of overpopulation on the environment. 

The world is our home and we are its protector. Overpopulation is putting a lot of strain on the natural environment, and it needs to be addressed in a civilised way. We need to make sure there is enough for everyone and that we are fulfilling our duty to Mother Nature.

Ans: The major causes of overpopulation are high birth rate, lack of education and illiteracy, poverty, cultural and religious beliefs, etc.

Ans: Some of the least populated countries are Iceland, Suriname, Mongolia, San Marino, Liechtenstein, and Palau.

Ans: Overpopulation is a phenomenon where a particular species exceeds the carrying capacity of the environment. The global population has increased by 1.2 billion in the last 20 years. This was the biggest population boom, putting a heavy strain on the natural environment. Overpopulation is majorly caused in developing countries, because of factors like lack of education and illiteracy, higher birth rates, poverty, etc. Proper government actions are required to address overpopulation, such as educational and family planning programs, women empowerment, job opportunities, etc.

• Population Explosion Essay

Essay on Population Explosion

After the Republic of China, India is the most populous country in the world. Presently, India is the second-largest populated country in the world that occupies 2.4% of the world’s land area and represents 17.5% of the world’s population. This means that one out of six people on this planet is an Indian.

It is estimated by the United Nations that India with 1.3 billion inhabitants would surpass China’s population of 1.4 billion by 2024 to become the world’s most populous country. Population Explosion is considered as a threat and burden on the Earth.

What is Population Explosion?

Population Explosion refers to the rapid increase in the number of people in an area. It is a situation where the economy of the country cannot cope up with the rapid growth of the population. Furthermore, in simpler words, it is a situation where the economy cannot provide proper facilities to its people.

Evidently, the largest contributing countries to population explosion are the poorer nations and are termed as developing countries. In India, the state of Uttar Pradesh is the most populated state and Lakshadweep is the least populated. Hence we can say that population explosion is inversely related to the development of that area.

Population Explosion has become the mother of evils in our country because too much population is trapping people in a web of poverty and illiteracy that further escalates the problem. Any time of the day, whether it is a metro station, airport, railway platforms, road, highway bus stop, shopping mall, market, or even a social or religious gathering, there is always a swelling crowd of people in India.

Causes of Population Explosion

The major cause of this population explosion is the difference between the birth rate. The birth rate is the number of individuals born in a population in a given amount of time. The human birth rate is the number of individuals born per year per 1000 in the population. For example, if 35 births occur per year per 1000 individuals, the birth rate is 35 ) .

The death rate is the ratio between deaths and individuals in a particular population during a particular period. In simple words, the incidence of deaths in a given population during a defined time (such as one year) is expressed per 1000 individuals ).

Apart from these, some other factors are partially responsible for population explosion, such as:

A decrease in infant mortality rate (Mortality rate refers to the number of deaths of infants below the age of 6 months.), 

The increase in life expectancy (An estimate of the average number of additional years that a person of a given age can expect to live). 

Earlier the life expectancy of people was around 55-60 years. Now the average age of a person has increased to 70-75 years.) but due to better and improved medical facilities, we can now increase the life expectancy of people. 

Earlier, there was a balance between the birth and death rate due to limited medical facilities, people dying in wars, and other calamities. According to the 2011 census, the birth rate has actually come down but then the death rate has also declined due to the medical advancements. 

Illiteracy is another cause of an increase in population. Low literacy rate leads to traditional, superstitious, and ignorant people. For example, Kerala has a very high literacy rate and it constitutes only 2.76% of India’s population as compared to Uttar Pradesh having maximum illiteracy rate and forms 16.49% of the population. Educated people are well aware of birth control methods. 

Family planning, welfare programs, and policies have not fetched the desired result. The increase in population is putting tremendous pressure on the limited infrastructure and negating India’s progress.

The superstitious people mainly from rural places think that having a male child would give them prosperity and so there is a considerable pressure on the parents to produce children till a male child is born. This leads to a population explosion. 

Poverty is another main reason for this. Poor people believe that the more people in the family, the more will be the number of persons to earn bread. Hence it contributes to the increase in population. 

Continuous illegal migration of people from neighbouring countries like Nepal, Bangladesh is leading to a rise in the population density in India.

Religion sentiment is another cause of the population explosion. Some orthodox communities believe that any mandate or statutory method of prohibition is sacrilegious. It is difficult for India to exercise a check on the religious grounds for its secularism.

Impact Due to Population Explosion

The growth of the population has a major impact on the living standards of people. That is why, despite our incredible progress in the agricultural and industrial spheres, our capita income has not risen appreciably.

Hence given below are some of the major problems which are just because of the population explosion:

Natural Resources of that particular region: Natural resources are materials from the Earth used to support life and meet people’s needs. Hence if there are many people, then there is a high requirement for Natural Resources.

Unemployment: When a country becomes overpopulated, it gives rise to unemployment as fewer jobs support many people. The rise in unemployment gives rise to crime, such as theft, as people want to feed their families and provide them with basic amenities of life.

High Cost of Living: As the difference between demand and supply continues to expand due to population explosion, it raises the prices of various essential commodities, including food, shelter, and healthcare. It means that people have to pay more to survive and feed their families.

Poverty: Another major issue of population explosion is the increase in poverty as people are unemployed due to a lack of job opportunities and an abundant workforce. 

Illiteracy: Because of unemployment, they cannot provide better education to the coming generation, giving us back population explosion.

Starvation: When resources are scarce, starvation, ill health, and diseases caused by diet deficiency such as rickets become eminent.

Some Major Effects of the High Population are as Follows

The rapidly growing population in India has led to the problem of food scarcity and heavy pressure on land. Even though 60% of its population is engaged in agriculture, yet people do not get even the barely necessary amount of food. 

Generating employment opportunities for such a huge population in India is very difficult. Therefore, illiteracy is growing rapidly every year. 

Development of infrastructural facilities is not able to cope up with the pace of growing population. So facilities like transportation, communication, housing, education, and healthcare are becoming inadequate to provide provision to the people.

The increasing population leads to unequal distribution of income and inequalities among the people widened.

Unmanageable population size may lead to the failure of the government to provide the basic facilities to the people. 

Economic development is slow in a country where the population is growing at a very fast rate. This also leads to low capital formation. 

Ignorance, illiteracy, unhygienic living conditions, and lack of recreation have always been the cause of population problems in India. 

Rapid growth in population is also an indication of the wastage of natural resources.

Preventive Measures

To tackle this problem, the government needs to take corrective measures. The entire development of the country depends on how effectively the population explosion is stemmed. 

The government and various NGOs should raise awareness about family planning and welfare. Hoardings with slogans like “Hum do, humare do” and “Chota Parivar, Sukhi Parivar” should be put up in hospitals and other public places. These slogans mean that a small family is a happy family and two children for two parents. The awareness about the use of contraceptive pills and family planning methods should be generated. 

The health care centres should help the poor people with the free distribution of contraceptives and encourage the control of the number of children. 

The government should come forward to empower women and improve the status of women and girls. People in rural places should be educated and modern amenities should be provided for recreation.

So we can summarise the topic by stating that population explosion is a term used to state the rapid growth of people in a particular area. It is because of lack of education, illiteracy, lack of proper knowledge of sex education, rituals, and superstition in the country’s most populated area. 

Overpopulation results in a lack of development and exploitation of resources, whereas India’s strength in the global world in various fields cannot be ignored. By raising public awareness and enlisting strict population control norms, India will be able to tackle this issue.

It doesn’t mean that will happen very quickly and without any effort. It will take time because India constitutes one of the huge countries of about 138 Crore (2020) people. Proper, effective, and steady steps will lead India to a greater good.

 It helps the country control the population explosion and also helps to provide good results in several other things like the good environment, abundant natural resources, proper employment, proper literacy rate with high growth in development, etc.

All this could be possible if we take some measures and be good citizens of this country. So that is how we can overcome this issue of population explosion.

FAQs on Population Explosion Essay

1) What is Population Explosion?

Population Explosion refers to a rapid increase in people in a particular area. Occurring due to reasons like increased birth in the area, decreased mortality rate, and inflow of residents, population explosion may lead to shortage of resources, negatively affecting the development of the area.

2) How is the birth rate related to population explosion?

Birth rate is directly proportional to population explosion because of people’s lack of knowledge and literacy. Most common in poor families, where more children means more means of income, increased birth rate gradually results in a population explosion.

3) What are the measures to avoid population explosion?

Better education (specially for girl child), creating awareness of family planning, providing proper knowledge of Sex Education, etc. can be some solutions to tackle the issue.

4) What is the difference between death rate and infant mortality rate?

The ratio between deaths and individuals in a particular population during a particular period is the death rate, whereas the infant mortality rate refers to the number of infants below 6 months who died within the same period.

5) What are the major reasons for the population explosion?

The major factors responsible for population explosion are illiteracy, reduced mortality, increased birth rate, and life expectancy.

Important things to remember as you write your essays on population

Population involves both fauna and flora. I am confident that you have encountered reports stating how the populations of certain species like elephants, white rhinos, and tigers are diminishing; or how deforestation is affecting the population of trees which has increased the consequences of global warming in the world. The following guidelines will assist you in writing an essay on human population.

Essays on population need to be elaborate to enable the audience to understand your essay.  Such essays are also of great importance to the writer since writing increases their knowledge on the problem and issues facing population. You should, therefore, read widely and comprehend the information before writing your essay.

Various internet sources, books, encyclopedias, and government publications explain the meaning of population. One example is that ‘Population refers to the whole number of individuals or inhabitants in a region or a country. It also comprises of the people occupying an area.’ The topic has been given great significance since an exhaustive study provides policy makers with the relevant information to make crucial decisions affecting a particular populace living in a particular region. You can further develop this argument in the body where you can explain the significance of population and its study.

Your definition can include:

• The populace of people in a specific area
• The percentage of people, fish, animals, and birds in a particular area
• The immigrant populace in America
• The population of endangered species
• The population of individuals susceptible to crime, and social disorder

All these definitions will show your audience that you understand what population is. You can write this in the introduction alongside the things that your essay will tackle

The body can include the significance of populations. Ask yourself these questions how will the number of people in a specific area benefit the people, policy makers, and the nation? How will information about endangered species, immigrants, and individuals susceptible to crime, and social disorder benefit me as an individual, the community, policy makers, and the country? The answers to these questions will provide the importance of population study

Your essay should also tackle the issues and challenges facing population. Ask yourself these questions: How does the population of a region decrease? Some of the answers are because:

• Human beings stop copulating thus reducing the number of people in a particular region. Governments are solving this issue by encouraging families to increase their sizes by increased reproduction.
• There is warfare, the prevalence of killer diseases, and lack of basic needs.
• The population of animals decreases when they are killed for sport; they are valuable resources, or when they become extinct.

Research on the problems that nations’ face due to low population, and how individuals can curb the decreasing population. The answers will give you extensive information about the issue of low population.

Additionally, population increase affects the population. You should, therefore, ask yourself the causes of population growth. Some reasons are:

• The human populace has grown with the falling death rates that have reduced since the Second World War.
• The migration of individuals from one area to another has increased the population of some countries. For instance, the population of immigrants in the United States has increased its population tremendously.

You should also tackle the effects of increased population. What does it mean when the population of people multiplies with no increase in resources? Some of the effects include:

• Inadequate resources
• Inadequate infrastructure
• An increase in crime and disorder
• Formation of slums
• Increase of people living in the streets
• Increased unemployment
• Increased deforestation
• Global warming

Further, explain why information on low population and high population is beneficial to the society

You can also provide recommendations

Lastly, your essay should have a conclusion that summarizes the main parts of the essay. It should not be more than half a page unless instructed otherwise.

Over Population Essay with Outline

• Over-Population is a worldwide problem.
• The main causes of increasing population.
• A serious impediment in the way of economic development.
• India is projecting the struggle as “Muslim Fundamentalism.”
• A comprehensive plan of family planning.
• There is no religious injunction against birth control Islam.

Over-Population is a world-wide problem. Pakistan is one of the most populous countries in the world. The population is growing at a rate of 3.1 percent a year. Economists are baffled, sociologists are scared and politicians and administrators are worried. It has created various problems like unemployment, poverty and illiteracy.

The main cause of this extraordinary growth in our population is not excessive births. It is our victory against death and disease. Poverty and illiteracy are also the major factors of the increasing population. About 42 million adults are illiterate. They are unable to understand the disastrous effects of overpopulation.

The result of the increasing population is obvious. Much of our effort to raise the standard of living of our people has been nullified. The growth of population is neutralizing all developmental efforts. It brings distress to the community, to the family and to the individuals. In the words of one of our economists. “ To plan when population growth is unchecked is like building a house where the ground is constantly flooded.” It has become a serious impediment in the way of economic development.

To check over-population, it is necessary to launch a comprehensive plan of family planning. Our country is suffering from severe economic problems. The remedy is to reduce the number of births. In order to stabilize the relationship between population and the basic necessities of life, we must bring our birth-rate down form 3.1 to 1. It is essential for every young person to recognize the disastrous and detrimental results of over-population. We should behave with a sense of responsibility.

Many simple people wrongly believe that religion is against family planning. They take it as the killing of children and the disobeying of God. They blindly follow the reaching of Mullah and do not try to understand the true spirit of Islam. There is no religious injunction against birth control in Islam.

Human Population and the Environment Essay

Alien invasion, environmental benefits and challenges of urbanization.

A higher birth rate than the death rate of a species will lead to an increase in the population size of the species. Secondly, immigration into a given habitat at a faster rate than the emigration will also result to an increase in the population of the area.

Immigration is the movement of new species into the habitat from another habitat and this may be influenced by the presence of food and other resources in the new habitat that are unavailable from where the species are emigrating. Another factor that leads to the increase of the population is a reduction in the mortality rate.

When the mortality rate reduces for a particular population, the number of newly born surviving to grow into adulthood rises thus increases the population size (Zavaleta, Hobbs, & Mooney, 2001). Lastly, the total fertility rate of the population influences the rate of change in the population size.

The fertility rate of a given species will depend on the life history characteristics of the species such as the number of reproductive periods in the lifetime of the species and the number of offspring produced at each reproductive period (Berg & Hager, 2009).

In the nutria case, the high fertility rate and life history characteristic of the animal affect its population. The nutria reach the reproductive age when they are six months old and a mature female is capable of forty births in three years. Another factor affecting their population is the lack of a predator, which leads to a low infant mortality and death rate of the adult population. The absence of a predator causes the replacement rate of the nutria population to be much higher than its depletion rate (Messing & Wright, 2006).

When the land is depleted of the nutria’s food source, the population of the nutria will rapidly decline because of starvation. The nutria has a high daily food demand of about a quarter of their body mass. It would be difficult for the population to find a replacement food source within the same habitat that can sustain their population (Messing & Wright, 2006). Therefore, the nutria population will decrease significantly or wipe out entirely.

Speaker Notes

Introduction.

The term “Urbanization” refers to the transformation of a rural area into an urban area. An area that previously had the characteristics of a rural area gradually transforms into an urban area as its population increases and the dominant economic and social activities of the area change.

Contrasting urban areas and rural areas adequately offer the description of urbanization. While rural area populations work in occupations that directly extract natural resources such as fishing, logging and farming, their urban counterparts, as a result of industrial specialization, engage in occupations that relate to the transformation of the already harvested natural resources or the provision of services not directly related to the harvest of natural resources (Berg & Hager, 2009).

Cities represent urban areas that have fully passed the transition from being rural area and have the characteristic of diversity in race, ethnicity, religion and the social economic status of residents.

Challenges of Urbanization

As areas transform into urban areas they become more populated because they attract immigrants looking for better economic opportunities. The growth in population and the subsequent development of facilities to support the large population creates environmental problems in the urban areas.

One direct environmental impact is the encroachment of forests, wetlands, agricultural land and wildlife habitats. This encroachment changes the primary use of the given land and disrupts the environmental balance, which has consequences on the life of the urban residents and that of the biodiversity around them.

Encroachment into agricultural land leads to an immediate decrease in the food supply capacity of the adjacent rural area that supplies food to the urban area. Therefore, urban residents have to look further for food supplies and seek ways to make the dwindling agricultural land to produce more food per unit land size.

Another challenge of urbanization is the increased commuting distance necessitated by the large urban area. As cities grow geographically, residents have to commute longer distances to their work places, schools, hospitals and to access other social amenities or meet other people.

The increase in the commuting distance comes with an increase in the reliance on motorized transport with comes at a cost to the environment. Vehicles use fuels and emit airborne gases as their byproducts. The larger the number of vehicles used in a city, the greater the emission of the airborne gases to the atmosphere.

These airborne gases are pollutants to the environment because they affect the supply of clean gases such as oxygen beneficial to human and animal life. Vehicles also emit smoke that pollutes the environment by making visibility difficult. Moreover, the sound of vehicles especially in traffic jams as drivers hoot is disturbing to the listeners and is a form of noise pollution.

Another environmental challenge of urbanization is pollution of water. A characteristic of urban areas is the paving of roads, paths and parking lots. In addition, buildings cover any open grounds such that rain and wastewater has to be channeled over the surface through drainage systems into outlets or treatment facilities before it leaves the cities to join the natural river system.

The problem of artificial overflow of water is that it lacks the ability to sift toxic materials from the water before it joins the waterways. As water overflows on roads and other paved surfaces and roofs, it collects a lot of toxic materials that are later transferred into water ways and are consumed by aquatic life, animals and humans who are using the water.

When the rate of population increase in urban areas is much higher than the development of economic opportunities to sustain the population an imbalance arises. Additionally, developments of systems that adequately control the social character of the population have to match the population growth to prevent the social imbalance that arises.

Unprecedented growth of the urban population results to a strain on resources that can support such a high population, otherwise referred to as the carrying capacities of the urban area. An ideal population growth should be at a rate that matches the development of the necessary social amenities and economic capacities such as employment opportunities to support the growing population. Population problems blamed on urbanization lay squarely on the insufficiencies of the urban area to support its large population.

Urbanization becomes undesirable when it results to urban problems of matching facilities and the population that it supports. These challenges occur as sewage treatment, pollution, congestion, inadequate supply of clean water, limited availability of medical facilities, and few transport systems to match population growth among other challenges.

Benefits of Urbanization

Cities and other urban areas have more job opportunities than rural areas and can therefore support large number of people seeking opportunities for social and economic development. The concentration of diverse occupations and cultures in urban areas makes them the center for economic, education and cultural development.

Residents of urban areas have a faster and easier access to the available opportunities for interaction and personal growth that would otherwise require travelling long distance for the rural area resident. Urban areas also make it easy for authorities to conduct their administration duties.

In most cultures of the world, women, the disabled and the minority have limited access to economic opportunities; however, in urban areas the same marginalized people get employment in a variety of industries (Berg & Hager, 2009). In the following section we discuss two winning projects and how they overcame the challenges of urbanization discussed earlier.

Project on Sites and Services for Low-Income Family Groups Argentina

This project aims to address the challenges of providing a good quality residence to urban residents lacking the necessary economic ability to obtain their own land for development of houses. The project identified that despite the availability of land, the poor could not afford the high selling prices.

After the realization that speculators were responsible for the high price of land, the project acquired land that was later subdivided and allocated to poor residents who would afterwards pay for the land in installments without having to suffer the rising cost arising out of the speculation.

In addition, to ensure that the quality of life within the new residents was desirable, the project included the development of physical infrastructure for the low-income residents. The project included the development of roads, drainage facilities, light pillars and street lighting.

The project also addressed the supply of key services like electricity and clean water. To make the project sustainable, the development of the low-income site used the concept of a land bank where land is set aside for future allocation to low-income earners who would otherwise be unable to afford the speculative prices (UNESCO, n.d. a).

The Bronx Center Project – “Don’t Move, Improve” USA

This is a collaboration of the communities around the South Bronx area, which aims to revitalize 300 deteriorated blocks. In the revitalization plan, the project intended to create job opportunities for the community and avail job-training programs that would expand the economic opportunities for South Bronx workers, entrepreneurs and investors.

In coming up with the project, its managers realized that the urban area had been neglected and offered very little social and economic support to its residents making most of them to emigrate to look for better opportunities (UNESCO, n.d. b).

Overcoming Challenges: The Bronx Center Project – “Don’t Move, Improve” USA

In the Bronx center project, the managers focused on the redevelopment of dilapidated and abandoned buildings and using them as economic centers or administrative centers.

For example, an old courthouse was rehabilitated and designated as a community labor exchange building for residents seeking all types of employment. Throughout the implementation period of the project, the project managers engaged the community through different participating avenues so that the final development plans and designs benefited all community members.

Limited economic opportunities of the area led to an inadequate supply of affordable housing as residents earned low incomes. As a remedy, the project included the identification and addressing of the constraints that affect the low-income earners quest for housing.

This included provision of grant and loans for purchase of houses. The project also included the development of a new senior citizen’s residency. Finally the project, addressed the supply of social amenities be redesigning open spaces and streets in addition to development of transport facilities (UNESCO, n.d. b).

Overcoming challenges: Project on Sites and Services for Low-Income Family Groups Argentina

The project was able to provide a land bank for the low-income earners to shield them from the high land prices caused by speculation. It also made the land more affordable to low income earners by giving them an opportunity to pay in monthly installments in addition to letting them construct semi-permanent houses as they seek funds to develop their planned houses.

To make the project sustainable, beneficiaries were allowed to construct houses using their own resources so that there would be no dependencies associated with the success of the project.

To ensure the new residency remained desirable in providing a good quality of living, the project put in place measures limiting the number of houses that can be constructed on a single piece of land; and provided social services like roads, electricity and clean water to the site (UNESCO, n.d. a).

The human different non-progressive behaviors led to the causes of population explosion in Pakistan.

• Introduction
• Current scenario of population in Pakistan 

      2.1 Causes of overpopulation

      2.2 Women are not in workforce

      2.3 Early marriages cause increase in population

      2.4 Government failed spread awareness

      2.5  Religious teachings encourage increase in population

      3. Conclusion

"If the world is to save any part of its resources for the future, it must reduce not only consumption but the number of consumers." B.F.Skinner  

Overpopulation means number of populations jumps higher than the available resources of country. In stone ages and agrarian societies people believe a greater number of manpower in order to be strong both socially and economically. The mindset is continuing in Pakistan even in postindustrial society. People still believe large population is symbol of power and strength. Unfortunately, Pakistan is one of those countries where the population is much larger than its economy. The human of Pakistan’s different non-progressive behavior led to the causes of population explosion. The main causes of overpopulation in Pakistan is lack of women participation in workforce, early marriages, failure of government to sensitized people and religious teachings that encouraged people to increase population.

Comparing the population of Muslims countries, According to World Bank Pakistan is leading in population growth rate with 1.89 percent leaving behind Bangladesh, Indonesia, Iran, Turkey, Morocco, Egypt and Malaysia at a growth rate between 1.2 to 1.6 percent. Pakistan’s population was 33 million in 1947. It was among those countries that started family planning program 1960s. Although Pakistan not a stable country right after independence but with next 15 years it develops very fast due to low population. Now, it is the 5th largest population in the world and one of the worst in economies. Population census 2017 reported that 207.68 million people living in Pakistan. According to the experts, under the same growth rate, the population of Pakistan would be greater than of China by the year 2035. 

First, women are very less in workforce in Pakistan due to cultural pattern of pattern. The male dominant society discourages women participation in workforce. Women are expected the look after household jobs. House wives are mothers of many children as compare to those women who are busy to advancement of their career at offices. Thus, lack of women participation in workforce causes population rate high.

Second, early marriages cause population expansion.  UN Women reported in 2020 that Pakistan has the 6th highest number of girls that married before the age of 18 in the world. Those girls who married early age usually have many children. As soon as a girl grow parent start thinking of their marriage because it is a general perception in society that girls should be married in early age. Although, early marriages are not allowed by law of Pakistan but it is very common all over the country. Those who are convinced regarding early marriages they have religious justification. Therefore, early marriage trend in Pakistan increasing the population of the country.

Third, government as an institution failed to aware masses to control birth rate. Government has resources for advertisement but normally it not visible anywhere. State has relevant institution but they are not functional. Actually, politicians, government officials and other school of thought inspired from religious teachings that is why their approach to population control projects are very passive All in all, institution of the state unsuccessful to aware people to use population-controlled methods.

Finally, religious factors playing a strong role to increase population in Pakistan. The poor believe that God will arrange food for their children so with that hope people are motivated to increase the number of their family members. Islamic teachings boost Muslims to increase Islamic community in order to strengthening the Islam. Islam also encourage polygamy therefore population increase and multiplies. Hence, Islamic teachings are source of inspiration for people to increase the Ummah.

To summarize, overpopulation cause in Pakistan by attitude of people and government.  Common people believe women should stay at home and control the affair of kitchen and children. Early marriages playing major role to boost the population. Government failed to aware the masses to control the birth-rate because it is not the priority of state to sensitizes masses in this regard. Furthermore, religion as a most dominant institution encourage people to increase the number of Muslims community. However, increase in population is not always a negative impact, China has proved that large population can contribute the progress and development of country, if many dominant factors not controlling to birth rate then government should adopt china’s policy to develop the nation.

Three key takeaways from donald trump’s iowa town hall, donald trump’s claim of absolute immunity rejected: what next, what is donald trump’s ‘hush money’ trial all about, how the world reacted to trump’s arraignment.

Police said the man, who was born in 1987, did not appear to be targeting Trump or others involved in the trial.

During the incident, which took place on Friday, the fourth day of Trump’s trial on criminal charges of falsifying business records, Azzarello threw pamphlets in the air before using an alcohol-based cleaning substance to douse himself and light the fire.

Police had said earlier that he was being viewed “as sort of a conspiracy theorist”.

Trump, the first former US president to face criminal charges, is on trial in connection with hush-money payments he allegedly made to adult film star Stormy Daniels.

Many police officers were present at the scene on Friday as part of the extensive security precautions to ensure the safety of the trial.

Journalists from across the world were also waiting outside the court, and some were live on air when Azzarello self-immolated.

Police had said the man had not breached any security checkpoints to access the park across from the court, and that he had recently travelled from Florida to New York.

Authorities said following the incident that they are reviewing security protocols and considering shutting down access to the park where Azzarello set himself ablaze. The side street where Trump enters and leaves the building is off-limits to everyone.
