The End of the World that human beings worry about is primarily a collapse of their cultural world. The world – Planet Earth and the life upon it – will go on after human civilization fails. It went on after an asteroid wiped out the dinosaurs. Something else will evolve after humanity has made everything but insects and stupid yappy dogs extinct. Life will endure even after the arrogant apes with delusions of grandeur pass away. Heck, maybe some of those apes will figure out a way to stick around.
