Warning: Flammable.

This commentary says it better than I could. It's a very dangerous cycle we're getting into, with the current frenzy to "save the planet". How long will it be before we've burnt all our food for fuel, food prices are out of reach for the already-strapped middle class, and the left-wingers who began the global warming battle cry are compelled to raise taxes so the government can pay for America to eat. Hey! maybe then the obesity crisis won't be such a problem.
