PETROLEUM FUELS AND BIO FUELS - A CONTRAST

How are petroleum fuels and bio fuels different?

Petroleum fuels are made by refining the residues of living things that died millions of years ago. These fuels are used, among many other uses, to increase the efficiency of food harvesting.

Bio fuels are made by refining the residues of living things that we must first grow, then kill. Bio fuels are made of food, and diminish the food harvest (because the food is being refined into fuel).
