Suggested reading. 'The World Without Us' by Alan Weisman, 2007. In a nutshell. We won't be missed and the world will heal. Couldn't put it down.

We're far too unstable and not nearly smart enough to survive. In a few million years, there will all sorts of new species filling the niches we eradicated.
