Climate Change: Environmental Issues
Causes of Climate Change
The number one motive force of climate exchange is the greenhouse impact, a natural manner improved by using human sports. Here are the primary reasons:
Greenhouse Gas Emissions:
- Carbon Dioxide (CO2): Released from burning fossil fuels (coal, oil, natural gas) and deforestation.
- Methane (CH4): Emitted from agricultural activities, especially farm animals, and fossil fuel manufacturing.
- Nitrous Oxide (N2O): Produced by agricultural practices, industrial procedures, and burning fossil fuels.
Effects on Environment and Human Health
Climate exchange has some distance-attaining outcomes for both the environment and human health:
Environmental Effects:

Overview of Major Environmental Laws in India
India has a complete criminal framework for environmental protection. Some of the important laws include:
- The Water (Prevention and Control of Pollution) Act, 1974: This Act targets to prevent and manage water pollution. It establishes pollution control boards at the central and state levels.
- The Air (Prevention and Control of Pollution) Act, 1981: This Act is aimed at preventing and controlling air pollution. It also provides for the establishment of pollution control boards.
- The Forest (Conservation) Act, 1980: This Act regulates the conservation of forests and their resources. It empowers the central government to protect forests and wildlife.
- The Wildlife Protection Act, 1972: This Act provides for the protection of wild animals, plants, and their habitats. It establishes national parks, wildlife sanctuaries, and tiger reserves.
- The Environment Protection Act, 1986: This is a comprehensive law that provides for the protection and improvement of the environment. It empowers the central government to take measures for the prevention and control of pollution.
- The Biological Diversity Act, 2002: This Act provides for the conservation of biological diversity, sustainable use of its components, and fair and equitable sharing of the benefits arising from the use of biological resources.
International Environmental Agreements
India is a signatory to numerous international environmental agreements, which include:
- The United Nations Framework Convention on Climate Change (UNFCCC): This treaty aims to stabilize greenhouse gas concentrations in the atmosphere.
- The Kyoto Protocol: This protocol commits industrialized countries to reduce their greenhouse gas emissions.
- The Paris Agreement: This agreement aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels.
- The Convention on Biological Diversity (CBD): This convention aims to conserve biological diversity, use biological resources sustainably, and share the benefits from the use of genetic resources.
Role of Government and NGOs
The government plays a crucial role in environmental protection through legislation, policymaking, and implementation. Government agencies like the Ministry of Environment, Forest, and Climate Change and the Central Pollution Control Board are responsible for enforcing environmental laws and regulations.
Non-governmental organizations (NGOs) also play a significant role in environmental protection. They raise awareness, conduct research, and advocate for environmental policies. NGOs often collaborate with the government and local communities to implement sustainable practices.
