Most fossil fuels are from 300-400 million-year-old plants and animals. They develop over millions of years, yet we use them quicker than they can be replenished.
This is further explained below.
Generally, fossil fuel is a substance containing hydrocarbons that were generated naturally in the crust of the earth from the remnants of plants and animals that have died and that are then recovered and burnt as fuel. Coal, crude oil, and natural gas are the three primary types of fossil fuels.
In conclusion, The majority of the elements that make up fossil fuels are derived from dead plants and animals that existed around 300–400 million years ago.
Therefore, it takes millions of years for them to develop, and we are consuming them at a rate that is far quicker than the rate at which they can be replaced by new ones.
