Answer 1

Step-by-step explanation:

Human beings used the resources indiscriminately and this has led to the following problems.

1) Depletion of resources for satisfying the greed of few individuals.

2) Accumulation of resources in few hands, which, in turn, divided the society into two, segments i.e. haves and have-nots or rich and poor.

Indiscriminate exploitation of resources has led to global ecological crises.
