Our use of corn for fuel has caused the prices of grain exports to rise, thus increasing food prices in developing nations where people already have enough problems preventing starvation. It also raises the prices for livestock feed here, bringing up the cost of meat and dairy. On a macro scale, corn based ethanol isn't as good as you would have led to believe. Plus, it's being heavily subsidized by the government so it's not really as cheap as you would think. Now if we would take a cue from Brazil and use sugar cane based ethanol, those objections go out the window since it essentially uses the wasted parts of the cane for fuel.
