Climate Change

I think that the earth has always been changing. When human being did not exist many millions of year ago, it had been changing. We will not argue that the disappearance of dinosaurs is due to human activities, yet they are extinct. Therefore, I think that our species is not to blame because it is itself victim of a cosmic system and change that even existed before him. Perhaps the extension of species living on earth is a phenomenon that cannot be reversed.
