“If humans were to go extinct, the earth would at least have a chance to repair itself…”
Chris Clarke writes at KCET.org:
Will we go extinct? There’s some thought that humans have already passed through a near-extinction event, related to the Toba eruption about 70,000 years ago, that may have reduced our total global population down to 15,000 people or fewer in southern Africa. That theory is questioned by some who cite the possibility of other survivng bands of humans. Either interpretation offers us hope for our species: humans can survive horrible catastrophes and rebuild.
Which means the question may not be so much “will we die out” as “will we wish we had.” If humans were to go extinct, the earth would at least have a chance to repair itself, evolve new biodiversity, and move on. But having the globe sprinkled with scattered bands of a few hundred survivors, each desperately scraping whatever sustenance might come from the planet their ancestors ruined? That’s a much more frightening prospect for both the planet and our great great grandchildren.
