Do you know
where gasoline comes from? It comes from processing oil. Where does most
of the world's oil come from? The oil that we pump out of the ground
today took millions of years to make.
So our oil supplies are not renewable -- once gone, gone forever.
An oil shortage is inevitable. Some analysts think that shortages may develop in 20 years or so. Then what? Prices will go up. Oil and gas may get so scarce that people start wars. What can we do? One option is to drill more wells. One problem is that oil wells create hazards to wildlife if there are spills from tankers or breaks in pipelines. On the other hand, if new wells only maintain our current supplies, no additional hazards are created.
