People are not allowed to use large amounts of fossil fuels.
Fossil fuels exist in very large quantities but they are difficult for scientists to locate.
Fossil fuels formed over millions of years and they are being used more quickly than they can be
replaced.
BOnly small amounts of fossil fuels even formed and early humans used most of the available
supply

Fossil fuels formed over millions of years and they are being used more quickly than they can be  replaced.

Explanation:

The best reason why he use of fossil fuels should be limited is that fossil fuels formed over millions of years and they are being used more quickly than they can be replaced.

Fossil fuels contains a very rich energy which is trapped within the carbon atoms and are obtained during combustion.

It takes several geologic years for the fuels to  form. On the other hand, our current rate of consumption of fossil fuels cannot be sustained because, consumption cannot be matched with the formation.
