what are fossil fuels ? why should we conserve it ?
Fossil fuels are the sources of energy which are formed in the geological past from the dead bodies or remains of living organisms like animals plants insects etc. which were compressed under the earth and sea levels and get converted into fuels by the high pressure and other environmental changes.
They are called as Fossil fuels , because, the remains of dead plants or animals or other organisms found from geological eras are called as fossils.
We should reduce the use of fossil fuels because these kinds of fuels are those fuesls which cannot be replinshed quickly,it takes millions of years to form fuel.so thus usage of these fuels should be reduced and should be use properly
