Question

why we should use coal and petroleum judiciously

Answer 1

Hi,
Coal and Petroleum are non renewable resources, once they get exhausted we can't get them back.
And also it is our duty to pass the present resources to the future generations as we had inherited the resources.
Hope this helps you.....☺

Answer 2

We should use coal and petroleum smartly and judiciously because they are a now an important part of our life and they are a non renewable resource too so using it properly must be our duty.
