Q2 :  

What happens when the rate of resource extraction exceeds that of their regeneration?


Answer :

Environment performs several functions, but its essential function of sustaining life carries much significance. Environment provides us with life supporting elements like Sun light, soil, water and air. On extracting resources at a more rapid pace than its regeneration, the carrying capacity of the environment reduces, leading to a failure in its life sustaining function. This results in environmental crises, one of the common problems faced by almost all the countries of the world.
