Fossil fuels are ______, ______ and ______.
उत्तर
Fossil fuels are coal, petroleum, and natural gas.

It requires millions of years to convert dead organisms into these fuels, but these known reserves will last only a few hundred years. Burning these fuels is a significant cause of air pollution, and their use is also linked to global warming. Therefore, it is necessary that we use these fuels only when necessary.
