Sure man is speeding things up, there are just too many of us. Population is the real issue but hard to deal with since we are all trying to find ways of living longer. Things like "The Polar Bears are going to go extinct" and other stuff like "The sky is Falling" attitudes make no sense. Firstly how did the polar bears survive the last time the Arctic was free of ice all year? They adapted and we will have to adapt. Sure it will kill property values in Vegas if they have to close the city due to no water but the cold dark north will be much more inhabitable. Not fun but is has always been happening. We were just not there to see it.
