Interesting article on ethanol-
Fuel for car may be food for trouble
I found the last paragragh to be interesting-
"But the grain it takes to fill a 25-gallon tank with ethanol just once would feed one person for a whole year. Converting the entire U.S. grain harvest to ethanol would satisfy only 16 percent of U.S. auto fuel needs."
So are we sacrificing too much of our fuel supply in order to drive our vehicles?
