Ans: 

  • Rio-Summit produced conventions dealing with climate change, biodiversity, forestry and recommended a list of development practices called Agenda 21.
  • It gave the concept of sustainable development to be combined economic growth with ecological responsibility.
  • Rio-Summit developed various contentious issues like Commons, Global Commons in global politics of the environment.

Q5: What is meant by Global Commons? How are they exploited and polluted?
Ans: The areas or regions located outside the jurisdiction of any one state and region, common governance by the international community are Global Commons i.e. Earth atmosphere, Antarctic Ocean floor, and outer space. They are exploited and polluted due to

  • Vague scientific evidence, their lack of consensus on common environmental issues.
  • North-South inequalities and their exploitative activities and competition lack proper management area out space.
  • Technological and Industrial development has also affected the earth’s atmosphere and ocean floor.

Q6: What is meant by ‘Common but differentiated responsibilities’? How could we implement the idea?
Ans: Common but differentiated responsibilities mean that the state shall cooperate in the spirit of global partnership to conserve, protect and restore the health and integrity of the earth’s ecosystem. As the states have common but differentiated responsibilities over various contributions of global environmental degradation. The developed countries acknowledge that the responsibility that they bear in the international pursuit of sustainable development in view of the pressures their societies place on the global environment and of the technological and financial resources they command.
 We could implement the idea with the help of conventions and declarations:

  • The Rio-Summit held in June 1992 produced conventions dealing with climate change, biodiversity, forestry and recommended a list of developed practices called Agenda 21.
  • The 1992 United Nations Framework convention on climatic change (UNFCCC) also emphasized that the parties should act to protect the climate system on the basis of common but differentiated responsibilities;
  • An international agreement is known Kyoto Protocol set targets for industrialized countries to cut their greenhouse gas emissions which support for global warming.

Q7: Why have issues related to global environmental protection become the priority concern of states since the 1990s?
Ans: Issues related to global environmental protection became the priority concern of states since the 1990s because at the global level, the environmental issues drew the attention of various states at the United Nations Conference on Environment and Development held in Rio-de-Janeiro, Brazil in June 1992 through Agenda 21:

  • Rio-Summit 1992 dealt with climatic change, biodiversity and forestry.
  • Agenda 21 combined economic growth with ecological responsibilities.
  • Kyoto Protocol set targets for greenhouse emissions. The above-mentioned conferences and summits raised the environmental issues at the global level to take steps by various states to check environmental degradation in a co-operative manner.

Q8: Compromise and accommodation are the two essential policies required by states to save Planet Earth. Substantiate the statement in the light of the ongoing negotiations between the North and South on environmental issues.
Ans: Compromise and accommodation are the two essential policies to save Planet Earth by the states but the states from North and South have different notions towards environmental issues:

  • The Northern States (Developed) are concerned with ozone depletion and global warming whereas southern states (Developing) want to address the relationship between economic development and environmental management.
  • The developed countries of the North want to discuss the environmental issues which stand equally responsible for ecological conservation.
  • The developing countries of the south feel that much of the ecological degradation in the world is created by developed countries through their industrial projects.
  • And if developed countries cause more environmental degradation they are supposed to take more responsibility onwards.
  • The developing counties are under the process of industrialization and they should be exempted from restrictions imposed on developed countries through various conventions like protocol etc. 
  • The special needs of developing countries must be taken into considerations in the process of development, application, and interpretation of rules of International Environmental Law.

All the above-mentioned provisions were accepted in Earth Summit, 1992 while adopting common but differentiated responsibilities.

Q9: The most serious challenge before the states is pursuing economic development without causing further damage to the global environment. How could we achieve this? Explain with a few examples.
Ans: The economic development can be achieved even without damaging the global environment by following practices:

  • In June 1992, Earth Summit provided some conservative measures for sustainable growth without damaging the environment anymore.
  • The Antarctic Treaty of 1959 covered Global Commons for mutual economic development.
  • Kyoto protocol cut greenhouse emissions from industrialized countries to protect the environment and to develop industries also.
  • Resource Geopolitics allocates and ‘ distribute natural resources among the nation states of the global arena for sustainable development of nations. Hence, the above-mentioned practices protect the global environment and even though the states are developing we could achieve this challenge only if we follow the provisions and practices mentioned in all these conferences and summits.

FAQs on NCERT Solutions for Class 12 Political Science - Environment and Natural Resources

1. What are natural resources?
Ans. Natural resources are materials or substances that occur naturally in the environment and are used by humans for various purposes. They can be categorized into two types: renewable resources (such as sunlight, wind, water, etc.) and non-renewable resources (such as fossil fuels, minerals, etc.). These resources play a crucial role in sustaining life and supporting economic activities.
2. Why is it important to protect the environment and natural resources?
Ans. It is important to protect the environment and natural resources as they are essential for the well-being of both humans and the planet. Environmental protection ensures the conservation of biodiversity, prevention of pollution, and maintenance of ecological balance. Protecting natural resources helps in sustaining various ecosystems, ensuring the availability of vital resources for future generations, and mitigating the impacts of climate change.
3. How does human activity affect the environment and natural resources?
Ans. Human activities have a significant impact on the environment and natural resources. Deforestation, industrialization, pollution, overexploitation of resources, and climate change are some of the ways in which human activities degrade the environment. These activities lead to the loss of biodiversity, depletion of natural resources, pollution of air, water, and soil, and disruption of ecosystems. It is essential to adopt sustainable practices to minimize these negative impacts.
4. What are the consequences of depleting natural resources?
Ans. Depleting natural resources can have severe consequences for both humans and the environment. It can lead to resource scarcity, which can disrupt economies and increase social inequality. Depletion of forests can result in loss of habitat for wildlife and contribute to climate change. Exhaustion of non-renewable resources like fossil fuels can cause energy crises and environmental pollution. Conserving and managing natural resources sustainably is crucial to avoid these consequences.
5. How can individuals contribute to the conservation of environment and natural resources?
Ans. Individuals can contribute to the conservation of the environment and natural resources in several ways. They can practice sustainable living by reducing their energy consumption, conserving water, recycling waste, and using eco-friendly products. Planting trees, supporting conservation organizations, and spreading awareness about the importance of environmental protection are also effective ways to contribute. Small individual actions, when combined, can make a significant positive impact on the conservation of natural resources.
