Ethanol gets a bad trip because it is not fully utilized yet. Therefore, I add the following statement from http://healthandenergy.com/ethanol.htm

“If all the automobiles in the United States were fueled with 100 percent ethanol, a total of about 97 percent of U.S. land area would be needed to grow the corn feedstock. Corn would cover nearly the total land area of the United States.” -David Pimental, a leading Cornell University agricultural expert

I add with glee, my own quote:
“If all the automobiles in the United States were fueled with 100 percent ethanol, a total of about 97 percent of U.S. land area would be needed to grow the corn feedstock. Corn would cover nearly the total land area of the United States unless we develop a better corn. Through better corn that yields double the corn or energy, imagine what it could do for our economy.”-Robert Atkinson, First Year College Student

I have no problem saying a Cornell expert, while right, is only fueling the fire to keep destroying our planet.
