Why do we need to use our environmental resources judiciously

We need to use our natural resources judicially for the following reasons:

To preserve them for future generation as these resources are limited in nature. 

Many natural resources are necessary for our survival. It may be difficult to imagine that we could ever run out of fresh water, clean air, and good soil for growing food. .

Theses resources take millions of years to form again like coal, petrol.

They are important to maintain ecological balance in nature like forests, water etc.

The indiscriminate use of natural resources like coal , petrol degrades our environment causing water, air pollution and green house effect.
