Climate Change and the Food Crisis

OK, I can kind of see people getting a little annoyed at the climate change problem because of the rise in food prices. Probably all the basic feedstuffs being diverted towards the production of ethanol is part of the problem. But why are we still doing this in light of recent studies that biofuels aren't a solution to the climate change problem? What's the point of paying researchers to do these studies if we're not going to listen to what they say?
