Although coal and petroleum are produced by the degradation of biomass,we still need to conserve them. Why?

(N/A) Both coal and petroleum are fossil fuels that take millions of years to form from the remains of ancient biomass. Because the rate at which we are consuming these resources is significantly faster than the rate at which they are being naturally replenished,they are non-renewable and will be exhausted in the near future. Therefore,it is essential to conserve them.
