Frequently Asked Questions
What are the two major functions of the environment?
The two main functions are supplying resources (renewable and non-renewable inputs for production) and assimilating waste (absorbing the refuse and pollution generated by human activities).
What is the difference between renewable and non-renewable resources?
Renewable resources can be replenished naturally over time, such as trees and solar energy. Non-renewable resources are finite and get exhausted with use, such as coal, petroleum, and minerals.
How can India achieve sustainable development?
India can achieve sustainable development by using non-conventional energy sources (like solar and wind), promoting organic farming, adopting cleaner technologies, spreading environmental awareness, and managing waste effectively.
