Frequently Asked Questions
What are the four vital functions of the environment?
The four vital functions are: supplying resources (renewable and non-renewable), assimilating waste, sustaining life by providing genetic and bio diversity, and providing aesthetic services.
What is the difference between renewable and non-renewable resources?
Renewable resources are those which can be used without the risk of their getting depleted (e.g., trees, water), whereas non-renewable resources are those which get exhausted with extraction and use (e.g., fossil fuels, minerals).
How does economic development cause environmental degradation?
Rapid industrialization, urbanisation, and intensive agriculture lead to excessive resource extraction, deforestation, and generation of toxic wastes, which exceed the assimilative capacity of the environment.
