In California they plan to implement another registration just for your cars carbon foot print, add that with breathing..and your taxed for breathing..

Also, carbon was more abundant when dinosaurs where alive. From what I recall it was when the earth was most alive, studies have been done proving more carbon equals more plants, equals healthier earth, you pull carbon you have no planet.

Just food for thought, protest carbon footprint taxes and any other charges. It is a joke, fat cats get fatter while you starve in a dying economy.
