I think they all have it wrong. Some say it's a natural occurance that happens with the Earth. Others say it's caused by mans' lack of caring for the enviroment. I believe they both have a hand in "global warming". It isn't an "either/or" situation. We have proof if Ice Ages and warming periods through out the Earth's known history. Yet I do believe that man is causing an unatural effect on what is otherwise a natural occurance. So, do I think it's just natures way or man's harming of the earth? Actually I think it's both. So with that said...Pick A Topic!
