Frequently Asked Questions
What are the two main functions of the environment?
The two vital functions are supplying resources (renewable and non-renewable inputs for production) and absorbing waste generated by economic activities.
Why is the absorptive capacity of the environment currently exceeding?
Absorptive capacity is exceeded because human activities, industrialization, and population growth generate waste at a rate much faster than natural processes can break down and assimilate it.
What are some strategies for achieving sustainable development in India?
Key strategies include using non-conventional sources of energy (solar, wind), promoting organic farming, adopting cleaner technologies, recycling waste, and spreading environmental awareness.
