FAQs on NCERT Textbook - Environment and Natural Resources - Political Science Class 12 - Humanities/Arts

1. What is the importance of natural resources?
Ans. Natural resources are vital for the survival and development of all living organisms, including humans. These resources provide us with essential materials like food, water, and air, as well as energy sources like fossil fuels and renewable energy. They also support various ecosystem services such as climate regulation, water purification, and biodiversity conservation.
2. How can we conserve natural resources?
Ans. Conserving natural resources is crucial to ensure their sustainable use for future generations. Some ways to conserve natural resources include practicing energy efficiency and conservation, reducing waste generation, promoting recycling and reuse, adopting sustainable agricultural practices, protecting and restoring ecosystems, and promoting sustainable management of water resources.
3. What are the main causes of environmental degradation?
Ans. Environmental degradation is primarily caused by human activities such as deforestation, pollution (air, water, and soil), overexploitation of natural resources, habitat destruction, climate change, and urbanization. These activities result in loss of biodiversity, soil erosion, water scarcity, air pollution, and climate change, leading to the degradation of ecosystems and the environment.
4. How does climate change affect natural resources?
Ans. Climate change has significant impacts on natural resources. Rising temperatures, changing precipitation patterns, and extreme weather events can affect ecosystems, water resources, agriculture, and biodiversity. These changes can lead to habitat loss, species extinction, reduced crop yields, altered water availability, increased frequency of natural disasters, and disruption of ecological processes, ultimately affecting the functioning of natural systems.
5. What are the strategies to promote sustainable development?
Ans. Sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. Some strategies to promote sustainable development include adopting renewable energy sources, implementing sustainable land and water management practices, promoting sustainable consumption and production patterns, integrating environmental considerations into policies and decision-making processes, investing in education and awareness, and fostering international cooperation for environmental conservation.
