fact. ill find the link where i read it but its 3 in the a.m. so ill do it later. factorys in china have had more of an effect on the polution of the world and global warming, then suvs in america but one blame is totally blammed on suvs and high gas burning vehicles. think about that. but its our suvs not the factorys doing it. i call bull shit. second fact the average earths temperature change in the last 500 years or so was ONE MILLIONTH of a degree increase..........yea u read that right. along with us having record lows in temperature in our area alone. man those heavy poluting suvs are really taking a toll on the earths temp. the earth was made to change temperatures. its called nature. the theory of global warming needs to be let go. its been talked about for way too long and nothing we do is going to change the way temperatures are going.
