I don't for a moment consider ethanol to be taking food away from anyone. I do wish those that claim such a great environmental benefit comes from its usage would consider the impact resulting from the farming procedures needed to see the crop to harvest. It seems the studies always concentrate on burning the stuff in an engine, and never on what's needed to get it to that state.
I think a study that compared the environmental impact beginning from obtaining and refining petroleum all the way to burning it in the engine, to planting, growing, and harvesting the crop AND turning it into ethanol and burning that in the same engine, would be interesting.
