Introduction – Environment and Natural Resources in Global Politics
Environment and natural resources have become central issues in world politics, especially since the second half of the twentieth century. Class 12 Political Science Chapter 8 explains how ecological challenges like global warming, deforestation, and resource depletion are no longer local problems — they are global political concerns that demand international cooperation.
For CBSE Class 12 students, understanding this chapter means understanding why nations sometimes agree and sometimes clash over how to protect the planet and share its resources.
Meaning of Environment and Natural Resources – Class 12 Political Science Chapter 8
The word “Environment” comes from two parts: “Pari” meaning around, and “Avaran” meaning to cover. Together, they describe everything that surrounds and supports life — plants, animals, water, air, and soil.
Natural resources are the materials that humans obtain directly from nature for survival, growth, and development. Food, water, timber, minerals, and fossil fuels are all examples of natural resources that human civilizations have depended on since ancient times.
Both the environment and natural resources are deeply connected. When one is damaged, the other suffers too. This is why Class 12 Political Science Chapter 8 treats them as a single, inseparable topic in the context of global politics.

Causes of Environmental Pollution – Key Concepts from Chapter 8
Why is Environmental Degradation a Global Crisis?
Environmental pollution has grown into one of the most serious challenges facing humanity. Class 12 Political Science Chapter 8 notes identify several major causes behind this crisis:
- Rapid and unchecked population growth placing pressure on natural systems
- Large-scale deforestation for agriculture, industry, and urban expansion
- Overuse and mismanagement of natural resources
- Industrial expansion without adequate pollution controls
- Excessive dependence on private transport and fossil fuels
- Political negligence and weak environmental governance
- Depletion of the ozone layer due to harmful chemical emissions
- Rising global temperatures caused by the greenhouse effect
- Shrinking agricultural land and growing scarcity of clean drinking water
- Increasing pollution alongside declining resource availability
These interconnected problems threaten not just ecological balance but the very survival of human civilization. This is why environment and natural resources have become a central concern in Class 12 Political Science Chapter 8.
Measures to Protect the Environment – Chapter 8 Solutions
Addressing environmental degradation requires action at both the national and international level. Class 12 Political Science Chapter 8 suggests several important measures:
- Controlling population growth through education and policy
- Conserving forests and promoting afforestation programs
- Adopting eco-friendly and cleaner technologies in industry
- Using natural resources responsibly and efficiently
- Encouraging the use of public transport to reduce emissions
- Launching public awareness programs on environmental responsibility
- Strengthening international cooperation through treaties and agreements
No single country can solve this crisis alone. Sustained global cooperation remains the most powerful tool available.
Limits to Growth and Early Global Awareness – Class 12 Chapter 8
The Club of Rome Report (1972)
In 1972, a group of scholars known as the Club of Rome published a landmark book titled “Limits to Growth.” This publication warned the world that as the global population continues to grow, natural resources are being consumed faster than they can be replenished.
The book was a wake-up call for governments and international organizations, pushing environmental concerns into mainstream political discussions for the first time. It remains one of the most referenced works in the study of environment and natural resources in Class 12 Political Science.
Our Common Future (1987)
Another important report, titled “Our Common Future,” was released in 1987. It clearly warned that existing models of economic development were unsustainable and would cause serious harm to future generations unless fundamentally reformed.
This report introduced the concept of sustainable development — the idea that economic growth and environmental protection must go hand in hand, not in opposition to each other.
Earth Summit 1992 and Agenda 21 – CBSE Class 12 Political Science Chapter 8
The Rio Earth Summit
One of the most significant events covered in Class 12 Political Science Chapter 8 is the Earth Summit held in Rio de Janeiro, Brazil in 1992. Also known as the Rio Summit, it brought together:
- Over 170 countries
- Thousands of non-governmental organizations (NGOs)
- Several multinational corporations
The summit marked the moment when environmental concerns officially entered the mainstream of global politics.
North-South Divide on Environmental Issues
A major outcome of the Rio Summit was the recognition of the sharp divide between developed and developing countries on environmental responsibilities:
- Developed (Northern) countries prioritized issues like ozone depletion and global warming
- Developing (Southern) countries focused on balancing economic growth with environmental protection, arguing they needed policy flexibility to develop
What is Agenda 21?
The Rio Summit introduced Agenda 21, a comprehensive global action plan for sustainable development. It proposed that economic growth should not come at the cost of environmental damage.
Critics, however, pointed out that Agenda 21 placed greater emphasis on development than on actual environmental protection — a debate that continues in international environmental politics today.
External Resource: The full text and background of Agenda 21 is available on the United Nations Sustainable Development website, which tracks global progress on environmental commitments.
Global Warming and the Ozone Layer – Environment Chapter 8 Class 12
How Does Global Warming Work?
A thin layer of ozone gas in the upper atmosphere acts as a shield protecting all life on Earth from harmful ultraviolet (UV) radiation from the sun. When this layer is depleted by chemical pollutants, more UV radiation reaches the Earth’s surface.
This extra radiation:
- Raises global temperatures year after year
- Accelerates the melting of polar ice caps and glaciers
- Causes rising sea levels that threaten coastal populations and island nations
The primary gases responsible for global warming include carbon dioxide, methane, and hydrofluorocarbons, all of which are produced in large quantities by industrial and agricultural activity.
Common Property Resources and Global Agreements
Some resources belong not to any single nation but to all of humanity. These are called common property resources and include Earth’s atmosphere, the open oceans, and outer space.
Several international agreements have been established to protect these shared resources. The most important ones covered in Class 12 Political Science Chapter 8 are:
- Antarctica Treaty (1959) — protecting the Antarctic continent from exploitation
- Montreal Protocol (1987) — targeting the reduction of ozone-depleting substances
- Antarctica Environmental Protocol (1991) — strengthening environmental protections in Antarctica
Common but Differentiated Responsibilities – A Core Idea in Chapter 8
Why Should Responsibilities Differ?
Class 12 Political Science Chapter 8 introduces one of the most debated concepts in global environmental politics — Common but Differentiated Responsibilities (CBDR).
The idea is straightforward: while all countries share a common responsibility to protect the environment, they do not bear equal blame for the damage that has already been done.
Developed nations industrialized first and historically produced the vast majority of greenhouse gas emissions. Developing countries are still working to improve the living standards of their populations and cannot fairly be held to the same restrictions as wealthy industrialized nations.
This principle has shaped almost every major international environmental agreement since the 1992 Rio Summit.
The Kyoto Protocol (1997) – Important for CBSE Class 12 Exams
What is the Kyoto Protocol?
The Kyoto Protocol was adopted in Kyoto, Japan in 1997 and built upon the 1992 UN Framework Convention on Climate Change (UNFCCC). It is one of the most important international agreements discussed in Class 12 Political Science Chapter 8 notes.
Key facts about the Kyoto Protocol:
- It set legally binding emission reduction targets for developed countries
- Developing countries like India and China were exempted from mandatory emission cuts, given their minimal historical contribution to global pollution
- India signed and ratified the Kyoto Protocol in 2002
The Kyoto Protocol was a landmark step in applying the principle of common but differentiated responsibilities to actual international law.
India’s Role in Environmental Protection – Class 12 Chapter 8
India has consistently taken a responsible and proactive approach to environmental issues on the global stage. Class 12 Political Science Chapter 8 highlights India’s major contributions:
- Signed and ratified the Kyoto Protocol in 2002
- Supported emission reduction discussions at G-8 meetings in 2005
- Promoted the use of clean fuels through the National Auto Fuel Policy
- Passed the Energy Conservation Act (2001) to encourage energy efficiency
- Enacted the Electricity Act (2003) to expand renewable energy use
- Launched a National Biodiesel Mission to reduce dependence on fossil fuels
- Established the National Green Tribunal (NGT) in 2010 for fast resolution of environmental disputes
- Signed the Paris Agreement in 2016, committing to long-term climate action
- Aims to reduce emission intensity by 33 to 35 percent by 2030
- Working to expand forest cover and strengthen carbon sinks through COP-23 commitments
India’s approach reflects the balanced position it has consistently maintained — protecting the environment while also defending the development rights of emerging economies.
Environmental Movements Around the World – Chapter 8 Class 12
Environmental awareness has not come only from governments and international bodies. Ordinary people and grassroots organizations have played a powerful role in pushing for change.
Class 12 Political Science Chapter 8 notes several significant environmental movements:
- Forest protection movements in Mexico, Brazil, Indonesia, Africa, and India
- Campaigns against mining industries in Australia that threatened indigenous lands
- Protests against large dam projects in Thailand, China, and India — most notably the Narmada Bachao Andolan in India, which highlighted the human and ecological costs of large infrastructure projects
These movements show that environmental protection is not just a government responsibility — it is a cause driven by citizens who understand what is at stake.
Geopolitics of Resources – A Critical Section of Chapter 8
How Natural Resources Shape Global Power
Control over natural resources has always influenced global politics. Class 12 Political Science Chapter 8 explains this through three clear examples:
Timber: Western colonial powers historically exploited forests in Asia, Africa, and the Americas for shipbuilding, trade, and industrial development.
Oil: After World War II, nations with large oil reserves gained enormous strategic and economic importance. The Middle East became a geopolitical hotspot largely because of its oil wealth.
Water: Water scarcity has already led to serious conflicts. The dispute over the Jordan River between Israel, Jordan, Syria, and Lebanon is one of the most prominent examples of water-based geopolitical tension in the modern world.
As natural resources become scarcer, competition over them is expected to intensify — making this one of the most forward-looking sections of Class 12 Political Science Chapter 8.
Indigenous Peoples and Their Rights – Environment Chapter 8
Who Are Indigenous Peoples?
According to a 1982 United Nations definition, indigenous peoples are those who have lived in a particular region long before modern nation-states were formed. They maintain distinct cultural identities, traditions, and close relationships with the land they inhabit.
In India, indigenous people are known as Adivasis or Scheduled Tribes and make up approximately 8 percent of India’s total population. Most depend on agriculture, forests, and traditional practices for their livelihoods.
Why Do Their Rights Matter in Environmental Politics?
Indigenous communities are often the first to be displaced when large development projects — dams, mines, highways — are built in or near their territories. Protecting their rights is therefore directly connected to protecting the environment they have sustainably managed for generations.
The World Council of Indigenous Peoples, established in 1975, works to defend these communities internationally. Their demands include recognition of cultural identity, land rights, and protection from forced displacement due to development projects.
