thomas gold's theory on how petroleum may be created not from fossilized plants, but from methane deep in the earth's crust. meanwhile, bacteria in the crust slowly eat away at the oil as a food source.

this is a great read; see pdf download link on the page.

if the theory is right, we will have an enormous supply of petroleum -- not that i'd advocate wasting any... and yes, we should vigorously pursue alternative, unlimited, nonpolluting energy sources.
