This article succinctly states common sense: Don't burn your food to drive your car!
We've all heard of the poor people who burn their furniture to keep warm... same same. Biofuels is just another scam to prop up agribusiness faced with collapse and bankruptcy as climate change pulls the rug out from under them.
What kind of sense does it make to divert more acreage from food production at a time when climate change will be reducing the amount of land avaiable to produce food for people all over the world?
Furthermore, who benefits from biofuels? Trans-national corporations, yes. People who drive cars in affluent nations, yes. Poor people? No, sorry. People in third world nations? No, again, too bad for them. Living things all over the planet? Please, let's be serious.
There is one thing that demonstrates clearly, once and for all, the snake oil business of biofuels: the Bush administration supports and promotes it.
