I went and Watched this movie myself and it's a definitely reality, it's funny that all of the naysayers are saying it's a farce, I firmly believe it's because it's too frightening to them because to accept it is to accept the fact that most humans have to change the course that there on. Whether we like it or not we are of the Earth and the Earth is of us. We are basically burning up the planet, you could say we are a virus, I know that may sound silly to some but it is true. it's not just the pollution we should be concerned about it's also the world population growth. we are using up what little precious resources we have now, and the people we elect can't even decide on whether to end a war much less pick there noses. face it, it will happen whether we like it or not if we don't change Mother Nature will change for us.
