>Yeah collapse of civilization is not the end of it, Humanity wont end it. If we collapse we will rise again maybe it will take 1000s of years. I am talking at the time scale of millions of years of evolution. We have risen out of harsher climate than what's coming.

We've already mined all of the easy stuff to build this advanced civilization. It's not going to be so easy to do it a second time without the "low hanging fruit" available.
