Lets stop using the liberal myth building term fossil fuel. We burned up the mass of the dinosaurs along time ago. The planet takes carbon dioxide and turns it right back into hydrocarbon. This carbon cycle is very similar to the water cycle in concept. Hydrocarbon is simply the most efficient storage source of potential energy. When we burn hydrocarbon, we are not depleting the supply or carbon, only changing its form. As a chemist, i can take carbon dioxide and turn it right back into 'fossil fuel', without the use of a dinosaur. Its not economically viable right now, but some day, with the right catalyst it could, and would certainly make more sense than burning our food for fuel
