What a load of crap. Farms have been closing down for years because they can't sell crops. Biofuels would turn things around in many ways. Old and damaged food crops could be used for fuel instead of landfill. Fuel crops don't need people friendly fertilizer or insecticides, use sewage sludge and let the bugs have fun. There are a lot of rapid growth plants, that aren't of food interest, but would make great fuel. Genetically altered plants could be used for fuel (never understood why its such a scare as food). I think it would create a lot of jobs, strengthen local economies. Farming for fuel wouldn't involve an special care of the crops, as it wouldn't matter what the product looked like, how ripe (or over ripe). No special harvesters (might help with the border issues, sorry mexico). Wouldn't have to seperate anything, different type plants could grow together in the same fields. Not much worr about pest, majority of the damage is cosmetic. Bacteria would be killed when the fuel is rendered. Farming without the hassles. Really don't see how this will effect the world food supply.
Carbon based fuels will polute just the same, don't think enviroment friendly applies here, except more plants, cleaner air...
