Brazil destroys more of the rain foresty every year to make room for more sugar and corn. Let's see who has the last laugh in about 10-15 years. Bio fuels are still way off in the future for the USA, but at least we are working on it.
The area where sugar cane is grown to make ethanol is 1500 miles south of the rain forest/amazon basin. No rain forest is destroyed to make ethanol.
The production of corn per acre in the U. S. in 1940 was 40 bushels per acre; it is now 165 bushels per acre; in 15 years it will be 300 bushels per acre. The corn crop in the U. S. will go from its current 13 billion bushels per year to 26 billion bushels per year without the use of any additional fertilizer or land.
Technology has finally enabled the U. S. to find a way to move cars and trucks without dirty oil.
