Biofuels BAD for the environment

I had heard about the possibility of biofuels being bad before, but this is the first report I've seen that has actually come out and said that the rush to biofuels could actually be a bad thing. There are three basic theories that are at work here. First by using corn and other food products for fuel you are depriving people of food - particularly poor people. When the amount of food supply goes down the demand goes up along with the price - thus also depriving poor people of their corn/food. The second theory is that biofuels are now becoming a cash crop, so people are going to use up as much usable land as possible to grow those crops - including valuable rain forest land. The last theory is that because biofuels require a lot of water, much of the usable water in developing countries will be used and thus there will be less usable water for those who actually need to use it. If anything this is a wakeup call to be mindful of the side effects of the rush to save the planet.
