I reckon humans must be causing even Mars to start global warming? Al Gore is a piece of work. He has most of the democrates believing all the crap about that shit too. I think he's the one who has gas prices as high as they are. The ozone rebuilds itself. He says, electricty has alot to do with it? But,one of his mantions is $6000 a month!! +, he flys around in his own private jet.
