Frequently Asked Questions
What is the difference between renewable and non-renewable resources?
Renewable resources are those which can be replenished naturally over time, such as solar energy, wind, and forests. Non-renewable resources are finite and get exhausted with use, such as coal, petroleum, and natural gas.
Why is the environment facing a crisis currently?
The environmental crisis is primarily caused by population explosion, rapid industrialization, and urbanization, which have led to resource over-extraction, generation of wastes beyond the environment's assimilative capacity, and severe pollution.
How can India achieve sustainable development?
India can achieve sustainable development by promoting non-conventional energy sources (solar and wind), adopting organic farming, implementing strict pollution control laws, afforestation, and spreading environmental awareness.
