Electricity and Circuits Class 6 Notes Science Chapter 12

Introduction to Electricity and Circuits

Electricity has become so common that sometimes we forget its immense applications.

Advantages of Electricity:

• Light in our houses, offices, roads etc. even past sunset
• To operate pumps which in turn have a lot of applications
• Electrical appliances like refrigerator, fans etc.
• Building houses, installing equipment etc.
• Current is the flow of particles in a particular direction. E.g air currents that cause winds or water currents.
• When particles flow in an electric circuit to produce electricity, it is called an electric current.

Electric current

The flow of electric charges in a circuit is called an electric current. The direction is taken from the positive terminal to the negative terminal of the battery in an external circuit.

Electric Cell

• It is a small cylindrical structure which helps in operating the devices.
• A small metal cap is placed on one side and a metal disc is present on the other side.
• All cells have two terminals: Positive and Negative.
• The metal cap and metal disc are positive (+) and negative (-) terminals of the electric cell respectively.
• Chemical energy is converted into electrical energy inside a cell. When the chemicals are exhausted, the cell stops working.

• An electric wire is a conducting path in an electric circuit, through which current flows.
• It is usually made out of a metal that is a good conductor of electricity.

Electric Bulb and its working

• The outer covering is glass and the base is metallic.
• The part of the bulb which glows is called  Filament  and is made up of tungsten.
• The filament is attached to two wires. One of the wires is connected to the metal case at the base and the other wire is connected to the metal wire at the centre of the base.
• Base of the bulb and metal tip are the terminals of the bulb and they do not touch each other.

Electric circuit

• A closed-loop path, which the current takes is known as an electric circuit.
• When the path of the circuit is closed, current flows through it.
• When there is a break in the path (switch is open) then, the circuit is open and not conducting so the current does not flow.

Consider an electric cell and a bulb. The terminals of the cell are connected to the terminals of the bulb by the means of electric wires. Such an arrangement of cell and bulb is called an  Electric Circuit . The circuit is said to be complete in this case because of which electricity will flow and the bulb will glow.

Electric switches

Switch is an integral part of an electric circuit. It is a simple device which breaks or completes a circuit. When the switch is ‘on’, the circuit is complete. When the switch is ‘off’, current does not flow in the circuit. So an electric appliance will only work if the switch is ‘on’.

Conductors and insulators

• Any material that allows the electric current to pass through it is called as the conductor. Eg: metals like copper
• Materials that do not allow the free flow of current through it are known as bad conductors or insulators E.g.: Rubber, plastic

Short Answer Questions: 3 Marks

1. How does a light bulb produce light?

Ans: A thin wire like structure known as filament is present inside the bulb. When we switch on the bulb, electricity passes through filament causing it to heat up and glow to produce light. In this process the electric energy changes into light energy.

2. What is an electric circuit?

Ans: The closed path in which electric current flows is called an electric circuit. Generally, an electric circuit consists of wire, battery, switch and an appliance which needs electricity to work. The current in the electric circuit flows from the positive terminal to the negative terminal. The switch is used to break the flow of the current when the appliance is not in use.

3. How does a bulb fuse?

Ans: Inside the bulb there is a thin wire like structure called filament. Filament is made of substances having a low melting point. Filament gets heated and emits light when we switch on the bulb. But when there is excess flow of current through the filament it melts down due to excessive heat. This causes fusing of the bulb.

4. Explain the role of a switch in a circuit. What is it made up of?

Ans: An electric switch is a circuit component that can be used to control the flow of electricity through the circuit. It has the ability to both complete and break the circuit. A conducting substance is used to make the switch. The circuit is complete and power flows through it when the switch is in the "ON" position. The circuit is broken and power cannot flow through it while the switch is in the "OFF" position.

5. Label the parts in the following diagram. Indicate the positive and negative terminals.

Question 5. What is the purpose of using an electric switch? Name some electrical gadgets that have switches built into them. Answer: An electrical switch is used to open the circuit or to close the circuit due to which electrical gadgets start or stop. Electrical switch is used in many electrical gadgets such as: television, washing machine, electrical mixer, toaster, heater, etc.

Question 6. Would the bulb glow after completing the circuit shown in figure of Question 4, if instead of safety pin we use an eraser? Answer: No, since eraser is an insulator so it does not allow the current to pass through it. Hence, the bulb will not glow.

Question 8. Using the “conduction tester” on an object it was found that the bulb begins to glow. Is that object a conductor or an insulator? Explain. Answer: If the object is a good conductor of electricity, then current will pass through conduction tester and the bulb will glow. Hence, the object will be a conductor of electricity.

Question 9. Why should an electrician use rubber gloves while repairing an electric switch at your home? Explain. Answer: Our body is a good conductor of electricity and rubber is an insulator. During repairing work, if the body comes in contact with current carrying wire then there will not be any accident as rubber does not allow the passage of current through it. Hence, electrician should use rubber gloves while repairing an electric switch.

Question 10. The handles of the tools like screwdrivers and pliers used by electricians for repair work usually have plastic or rubber covers on them. Can you explain why? Answer: Plastic or rubber is an insulator which does not allow electric current to pass through it. The handles of the tools like screwdrivers and pliers used by electricians for repair have covering of plastic or rubber so that electric current may not pass through these tools to the body of the electrician to harm him.

NCERT Extended Learning Activities And Projects

Question 1. Imagine there were no electric supply for a month. How would that affect your day-to-day activities and others in your family? Present your imagination in the form of a story or a play. If possible stage the play written by you or your friends in school. Hint: Do it yourself.

Question 2. For your friends, you may set up a game “How steady is your hand?”. You will need a cell, an electric bulb, a metal key, two iron nails (about 5 cm in length), about one and a half metre long thick metal wire (with its plastic insulation scraped off) and few pieces of connecting wires. Fix two nails nearly one metre apart on a wooden board so that these can be used as a hook. Fix the wire between the nails after inserting it through the loop of the key. Connect one end of this wire to a bulb and a cell. Connect the other terminal of the cell to the key with a wire. Ask your friend to move the loop along the straight wire without touching it. Glowing of the bulb would indicate that the loop of the key has touched the wire. Hint: Do it yourself.

Question 3. Read and find out about Alessandro Volta who invented the electric cell. You may also find out about Thomas Alva Edison who invented the electric bulb. Hint: Do it yourself.

Objective: To make an electric bulb light up using an electric cell. Materials Required: Bulb, cell and connecting wire. Procedure:

• Take four lengths of electric wire with differently coloured plastic coverings.
• Remove a little of the plastic covering from each length of wire at the ends. This would expose the metal wires at the ends of each length.
• Fix the exposed parts of the wires to the cell and the bulb as shown in figure below.

• You can stick the wires to the bulb with the tape used by electricians. Use rubber bands or tape to fix the wires to the cell.
• Now, connect the wires fixed to the bulb with those attached to the cell in six different ways as has been shown below. For each arrangement, find out whether the bulb glows or not.

Observations: You connected one terminal of the electric cell to the other terminal through wires passing to and from the electric bulb. Note that in the arrangements shown in Fig. (a) and (f), the two terminals of the electric cell were connected to the two terminals of the bulb. Such an arrangement is an example of a closed electric circuit.

Conclusion: The electric circuit provides a complete path for electricity to pass (current to flow) between the two terminals of the electric cell. The bulb glows only when current flows through the circuit.

• Electric bulb: Electric bulb is the electrical device which converts electrical energy into light and heat energy.
• Filament: Filament is a thin wire in the bulb which is made up of tungsten metal and is used to emit light in the bulb. The Filament gets heated due to electric current. This heat is then converted into light.

Objective: To study the structure of a torch bulb. Material Required: A torch bulb. Procedure:

• Take out the bulb from a torch.
• Observe the bulb from outside and also from inside with a magnifying glass.
• List the various parts you could see.

Observations: The torch bulb consists of the following parts:

• Metal casing having grooves in the lower part.
• A small spiral of thin wire called filament is present.
• Two slightly thicker wires in the upper ends of the wires support the filament.
• The lower end of the one of the thicker wire is connected to the metal casing and that of the other wire to the metal tip at the bottom of the bulb.
• The metal tip and the metal casing are fixed in such a way that they do not touch each other.

Electric switch: Electric switch is a device by which an electric circuit can be easily completed or broken. The switch is ‘ON’ in a closed circuit and ‘OFF’ in an open circuit.

Objective: To make a simple and easy switch to use in our circuit. Materials Required: Two drawing pins, a safety pin (or a paper clip), two wires and a small sheet of thermocol or a wooden board. Procedure:

• Insert a drawing pin into the ring at one end of the safety pin and fix it on the thermocol sheet as shown in the figure.
• Make sure that the safety pin can be rotated freely.
• Now, fix the other drawing pin on the thermocol sheet in a way that the free end of the safety pin can touch it.
• The safety pin fixed in this way would be your switch in this activity.

• Now, make a circuit by connecting an electric cell and a bulb with this switch as shown. Rotate the safety pin so that its free end touches the other drawing pin and observe.
• Now, move the safety pin away and observe again.

Observations:

• The safety pin covered the gap between the drawing pins when you made it touch the two of them. In this position the switch is said to be ‘on’. Since the material of the safety pin allows the current to pass through it, the circuit was complete. Hence, the bulb glows.
• On the other hand, the bulb did not glow when the safety pin was not in touch with the other drawing pin. The circuit was not complete as there was a gap between the two drawing pins. In this position, the switch is said to be ‘off’.

Conductors: Conductors are the materials which allow the electric current to pass through them. Mostly metals are good conductors of electricity. Insulators: Insulators are the materials which do not allow the electric current to pass through them. Rubber and wood are insulators.

Objective: To find out which object is a conductor and which is an insulator. Materials Required: Three pieces of wire, a small torch bulb, a thick sheet of cardboard or wood, sticky tape, pencil cell and objects such as metal spoon, eraser, peel of wood, etc. Procedure:

• Connect a pencil cell to the socket which holds a small torch bulb.
• Attach clips to the bare ends of both wires.
• Hold various objects between the two clips.
• Observe if the bulb glows or not. Record your observations.

• The bulb does not glow when the free ends of the wires are in contact with some of the materials you have tested. This means that these materials do not allow the electric current to pass through them.
• On the other hand, some materials allow electric current to pass through them, which is indicated by the glowing bulb.

Conclusion: Materials which allow electric current to pass through them are conductors of electricity. Insulators do not allow electric current to pass through them.

Question 2. What is the difference between a conductor and an insulator? Answer: A conductor allows the passage of current through it whereas an insulator does not allow the passage of current through it.

Question 3. How does a bulb start glowing with an electric cell? Answer: When the electric cell is connected with conducting wire and the wire ends are connected to the bulb, the bulb glows immediately.

Question 4. If you touch an electric wire carrying current you get a shock, but if on the same wire, the birds sit they do not get any shock/current. Give reason. Answer: When we hold the wire carrying current then the circuit is closed and the current flows from our body and enters the earth but the birds sitting on the same wire do not get any current as the circuit is not complete. If the bird touches the earth wire, it will die due to electric shock.

Question 5. What is a switch? When we switch on an electrical appliance, what changes are we making to the circuit? Answer: The switch is a simple device which is used to open or close a circuit. When the switch is turned on, the gap in the circuit is closed and a complete circuit is made. Due to complete circuit, electricity starts flowing in the circuit and electrical appliance will now start working.

Question 7. Describe the positive and negative terminals of a cell. Answer: The metal cap of the cell is considered as positive terminal. It is indicated by sign (+). The metal disc or the container of the cell is the negative terminal. It is indicated by sign (-).

Question 8. What is a fused bulb? Why it does not glow? Answer: Bulb has a small filament inside it. If the filament of a bulb is broken, then such a bulb with broken filament is called fused bulb. The broken filament cannot complete the circuit. As a result, current cannot flow through the filament and fused bulb does not glow.

Question 9. What are the essential components or elements of an electric circuit? Answer: The essential components or elements of an electric circuit are:

• Electric sources (cell, battery).
• Electric appliances (a device for using the electric current).
• Conductor (for providing a path for the flow of current).
• Switch or key (for opening and closing the circuit).

Long Answer Type Questions

Question 2. What is a torch? How does it work? Answer: A torch is a portable electric lamp which uses two or more cells to light a small bulb. A torch contains a simple electric circuit. In a torch, two (or more) cells are connected to a torch bulb through a sliding switch. When the torch is needed to provide light, we close the sliding switch by pushing it forward so that the circuit is completed and the bulb lights up.

Question 3. What are the differences between conductors and insulators? Answer:

Question 4. Define the following terms: (a) Dry cell and (b) Secondary cell. Answer: a. Dry cell: An electric cell is used to operate objects like calculators and phones. It is a small source of electricity or electric current. It is also known as a pencil cell or dry cell. A dry cell has two terminals. One side that has a small circular metal cap is the positive terminal. It is marked with positive (+) sign. The other side has a flat metal plate behaves like the negative terminal and is marked with a negative (-) sign.

There are some chemicals inside a cell. These chemicals react to produce electricity. When the chemicals get used up, the cell stops producing electricity and the appliance stops functioning. These electric cells then . have to be replaced by new cells.

b. Secondary cell: Secondary cells are the cells that provide electrical energy to the gadget as a result of chemical reactions taking place in them. In these cells, electrical energy can be stored in the form of chemical energy and the stored chemical energy can be reconverted into electrical energy. Such cells are also called rechargeable cells. Lead accumulator and nickel- iron accumulators are two examples of secondary cells. They are mainly used in mobile phones, laptops and car batteries.

Question 5. What is the importance of electricity in our life? Answer: We use a variety of things in our day-to-day life that run on electricity such as fans, lights, televisions, radio, refrigerator and computer. Electricity makes it possible to light our homes, roads, offices, markets and factories even after sunset. This helps us to continue working at night. In the field of communication, electricity is also used as a medium for the transmission of signals. The different fields of our life which depend on electricity are rather wide.

Question 6. Mention the precautions that are advised while handling electric appliances. Answer: While handling electric appliances, the following precautions need to be taken.

• Do not operate an electric appliance or switch with wet hands.
• While using electric appliances, always wear rubber soled footwear. Rubber being a bad conductor of electricity prevents current from passing through our body.
• In case of a fire caused by electric spark, make sure that we should not throw water on electric appliances. Always use an extinguisher to put out electrical fires.

Electricity and Circuits Class 6 Notes - Chapter 12

According to the CBSE Syllabus 2023-24, this chapter has been renumbered as Chapter 9.

The Electric Cell

• Current is the flow of particles in a particular direction. For example, air currents that cause winds or water currents.
• When particles flow in an electric circuit to produce electricity, it is called an electric current.

Electric Current

The flow of electric charges in a circuit is called an electric current. The direction is taken from the positive terminal to the negative terminal of the battery in an external circuit.

For more information on the Flow of Current, watch the below video

To know more about Electric Current, visit the link below;

Electric Cell

• A cell is a source of electric power created inside by internal chemical reactions.
• When the chemicals inside the cell are exhausted, the cell needs to be replaced by a new one.
• Cells have two terminals: a positive and a negative terminal. In order for current to flow, the positive terminal must be connected to the negative terminal, and this polarity must be maintained.

Bulb Connected to an Electric Cell

• An electric wire is a conducting path in an electric circuit through which current flows.
• It is usually made out of a metal that is a good conductor of electricity.

Electric Bulb, and its Working

• It consists of a thin wire that glows due to the passage of current. This is known as the filament.
• An electric circuit provides a closed path for the current to flow. The terminals of the bulb are connected by wires to the electric cell.
• Sometimes the bulb does not glow as the filament gets fused (breaks) due to overheating.

An Electric Circuit

Electric circuit.

• A closed-loop path, which the current takes, is known as an electric circuit.
• When the path of the circuit is closed, current flows through it.
• When there is a break in the path (the switch is open), then the circuit is open and not conducting, so the current does not flow.

To know more about Circuit Component, visit the link below;

Circuit Component

An Electric Switch

Electric switches.

• Devices that are used to connect the circuit or break it.
• When the switch is connected, we call it ON, and when it’s not in contact (or open) with the circuit, the switch is OFF.​​​​​​

Electricity and Circuit – Conductors and Insulators

Conductors and insulators

• Any material that allows the electric current to pass through it is called the conductor. For example, metals like copper
• Materials that do not allow the free flow of current through them are known as bad conductors or insulators. For example, rubber and plastic

Access class 6 science chapter 12 – electricity and circuits notes.

Definition of Electricity

Electricity is the movement of charges (electrons) or electrical power through a suitable medium. For example, the wires used in homes. Electric currents can be produced by batteries, generators, inverters, dry or electric cells, or by converting other energy sources.

Electric Circuit:

A closed path known as an electric circuit delivers a constant flow of electrons or electric current from a source of voltage to the machinery in use. The term “current flow” refers to the movement of electricity in a circuit from one terminal of a power source, such as a cell, to another. The starting terminal is typically regarded as positive and the ending terminal as negative. A simple circuit consists of two wires connecting a bulb to a battery. As long as the battery is not dead and the bulb is not fused, it will begin to glow.

A circuit diagram is a representation of this current flow path or circuit using various symbols and notation for various components.

Open and Closed Circuits

When the path taken by an electrical current from one termin

al to its opposite terminal is uninterrupted and continuous, it is referred to as a closed circuit. However, if the same path is broken somewhere along the way, it is referred to as an open circuit.

Electrical Components 

• Wire: Wires are electrical conductors that connect two or more electrical components and allow current to flow. The wires are typically made of metals that are effective electrical conductors. The type of metal and wire size are chosen based on the application. 
• Bulb: It is a filament inside a glass case that is connected to two terminals and heats up when an electric current flows through it and emits light. Typically, tungsten wire coils are used to create the filament wire. The two terminals between which the filament is located receive the electricity. 
• Electric Cell or Dry Cell: It is a particular type of apparatus that captures chemical energy and transforms it into electrical energy that can be applied to various tasks. Positive and negative terminals make up its two terminals. Charges move from the negative to the positive terminal inside a cell, whereas the opposite occurs outside the cell. 
• Battery: A battery is a collection of two or more cells connected in series. 
• Switch: An electrical circuit uses this device to allow or restrict the steady flow of current. When activated, it creates a conducting medium between two gaps in a circuit, allowing the circuit to function. . When turned off, it breaks the circuit by removing the conducting medium from its gap.

An electric torch is made up of a battery, an LED (Light Emitting Diode) bulb, and the above-mentioned parts altogether.

Electrical Conductors and Insulators

The materials that permit the flow of electricity through them are known as electrical conductors. All metals fall into the category of excellent electrical conductors. The only non-metal that conducts electricity is carbon, which can be tested by laying wires across a pencil’s two ends.

On the other hand, materials that do not permit the flow of electric currents are referred to as insulators or poor conductors. Some examples of insulators include plastic, rubber, dry wood, PVC, etc.

Effects of Electricity

The passage of an electric current through a material is accompanied by a number of additional effects, some of which can be put to other uses or result in energy losses. Some of these effects are discussed below.

• Heating Effect: When an electric current passes through a conductor, heat is generated due to the conductor’s resistance to the flowing current. Electric heaters, ovens, and other devices use this effect to generate heat.
• Lighting Effect: When an electric current passes through the filament of an electric bulb,  the thin wire glows as a result of the current flow.
• Magnetic Effect: When an electric current is passed through the coil, the metal becomes magnetic. Electromagnets make use of the magnetic effect. An electromagnet is a magnet made up of a piece of iron or steel surrounded by a coil. 
• Chemical Effect: A solution ionises and breaks down into ions when an electric current flows through it. This chemical action is used in electroplating and electrolysis.

1. what is an electric circuit.

Electricity is defined as the flow of electrons or charges through a suitable medium of conduction, typically the wires that come from batteries, cells, or generators. A closed path of conduction known as an electric circuit enables a constant flow of electrons from one end of the current source to the other terminal end of the apparatus being used.

2. What are the various components of the electric circuit?

The following elements are necessary for an electric circuit to function properly so that electrons or charges can flow continuously through the medium of conduction. A cell, a device that transforms chemical energy into electrical energy, or a battery, which is a combination of cells, is one of the components. A switch is used to open or close the function of the circuit. Other components include wires used for conduction.

3. What are electric conductors and insulators?

To generate electricity, charge moves from one terminal end of the current source to the other. Conductors are the components in a circuit that permit the flow of current through them. All metals, carbon, and nonmetals, are recognised as being good electrical conductors because electrons pass through them with ease. Insulators, or poor electrical conductors, are objects that do not allow electrons to pass through them. For example, rubber.

4. What are the effects of electricity?

The passage of electric charges through a medium is usually accompanied by some effects. These effects are caused by electricity and are used for other purposes that help in the completion of various tasks. The different effects of electricity include the heating effect, which is used in electric heaters for iron, the lighting effect, which is used in light bulbs and other similar objects, and the magnetic effect, which is used in the field of electromagnetics.

The Protection of Global Commons| Class 12 Political Science Notes

The concept of ‘global commons’ refers to natural resources and regions that lie outside the political reach of any one nation-state and are considered common areas shared by all. These include the Earth’s atmosphere, outer space, Antarctica, and the high seas. The protection of these areas is crucial due to their universal importance and vulnerability to exploitation and environmental degradation. This article explores the various dimensions of global commons, the challenges in their protection, and the role of international law and organizations in safeguarding these vital resources.

Understanding Global Commons

Challenges in protecting global commons, international laws and agreements, role of international organizations, case studies, future perspectives and challenges.

Global commons encompass those parts of the planet that are not owned by any single entity but are shared among nations and peoples. These include:

• The High Seas : Areas of oceans not covered by national jurisdiction, beyond the Exclusive Economic Zone (200 nautical miles from a nation’s coast).
• The Atmosphere : The blanket of gases surrounding the Earth, crucial for climate regulation and life support.
• Antarctica : Governed by the Antarctic Treaty System, it is a landmass devoted to peace and science.
• Outer Space : Including celestial bodies and the orbital environments around Earth.
• Biodiversity : While not limited to commons, the diversity of ecosystems, species, and genes is vital for sustainability and is shared globally.

The protection of global commons faces numerous challenges:

• The tragedy of the Commons : This concept illustrates how individual users acting independently according to their self-interest can deplete or spoil shared resources, even against everyone’s long-term best interests.
• Jurisdictional Issues : Global commons often exist beyond the jurisdiction of any single country, making enforcement of laws challenging.
• Environmental Degradation : Pollution, overfishing, and the impacts of climate change are significant issues affecting the health of global commons.
• Economic Pressures : Economic imperatives often drive nations and corporations to exploit these resources unsustainably.

Several international laws and agreements have been established to protect global commons, including:

• The United Nations Convention on the Law of the Sea (UNCLOS) : Governs the use of the oceans and aims to protect the marine environment.
• The Antarctic Treaty (1959) : Establishes Antarctica as a scientific preserve and bans military activity on the continent.
• The Outer Space Treaty (1967) : Bans the placement of nuclear weapons in space and limits the use of celestial bodies to peaceful purposes.
• The Montreal Protocol (1987) : A successful environmental treaty that phases out the production of numerous substances responsible for ozone depletion.

International organizations play a crucial role in the governance and protection of global commons:

• The United Nations (UN) : Through various bodies like the UNEP and the International Maritime Organization, the UN spearheads initiatives to protect and manage the global environment.
• The World Trade Organization (WTO) : While primarily focused on trade, the WTO also deals with environmental issues related to trade.
• The International Whaling Commission (IWC) : Works to regulate whaling and promote whale conservation globally.
• The Amazon Rainforest : Often referred to as the “lungs of the Earth”, the Amazon is a critical global common for biodiversity and carbon sequestration. Efforts to protect it involve international cooperation and regulations.
• The Arctic : Climate change is making the Arctic more accessible to navigation and exploitation. The region is governed by the Arctic Council, which includes countries like the USA, Canada, Russia, and others.

The future of global commons protection lies in enhancing international cooperation, improving compliance with international laws, and integrating sustainability into economic and social policies. Challenges like geopolitical conflicts, economic disparities, and technological advancements continue to impact the effectiveness of global commons governance.

The protection of global commons is essential for maintaining global stability and ensuring sustainable development. While significant progress has been made through international treaties and organizations, ongoing vigilance, cooperation, and adaptability are required to address the evolving challenges faced by global commons. By understanding the importance and vulnerabilities of these shared resources, we can better appreciate the necessity of their protection for future generations.

FAQs on Class 12 Political Science Notes Chapter Chapter 6 The Protection of Global Commons

What are the global commons.

Global commons refer to natural resources and areas that are not owned by any single country or entity but are shared among nations. These include the high seas, the atmosphere, outer space, and Antarctica.

Why is the protection of global commons considered challenging?

Protecting global commons is challenging for the following reasons: Jurisdictional ambiguities : Since these areas do not fall under the sovereignty of any one nation, it’s challenging to enforce regulations. Varied national interests : Countries often have conflicting interests and priorities, which can complicate negotiations and enforcement of international agreements.

How does the Tragedy of the Commons relate to global commons?

The Tragedy of the Commons principle is highly relevant to global commons, as their shared nature means that without cooperative management, they are at risk of over-exploitation and degradation, leading to long-term negative outcomes for all.

What role do international treaties play in the protection of global commons?

International treaties are crucial in the management and protection of global commons. They provide a framework for cooperation and legal standards for usage that all signatory nations agree to follow. Examples include: The United Nations Convention on the Law of the Sea (UNCLOS) for the oceans. The Antarctic Treaty for Antarctica. The Outer Space Treaty for celestial bodies and outer space. These treaties help to establish guidelines and rules that are designed to prevent the overuse and ensure the sustainability of these resources.

Can global commons be effectively protected without international cooperation?

It is highly unlikely that global commons can be protected without robust international cooperation. Since these areas do not fall within the jurisdiction of any single nation, no one country can effectively manage or protect them alone.
