With the way we're going, 500 years is pushing it IMO. No way we'll last 50K--we don't learn from our mistakes, and we change too slowly to survive (mental change, not physical). We don't adapt...we destroy.
sure ! we can make a uber big space ship with plants, factory's everyday life (with an edge ofcourse ) and dump all the crap we get flying in space when the earth is ruined,.. a more clean idea would be better thought but i just mean ofcourse we can survive alot,.. we can think of something right?
Well definitely survive 2012 as thats been blown out of proportion, its just the end of a cycle (the earth goes through many cycles) according to researchers. So unless we destroy ourselves, then I recon so.
