Once upon a time in the West...

UN: Humans cause worst extinctions since dinosaurs...

...D. Keith Mano wrote a novel in the 1970's called The Bridge. In it, those who care more for "nature" than man have taken over and returned us to the Stone Age to save the planet from the scourge that is humanity.

Eventually, the ecocrats (my neo-logism, not Mr. Mano's) realize they cannot prevent the holy bacteria from being killed when evil humans inhale them, so they order the murder of the human race (including their own suicides).

We have been warned, kiddies.

These morons hate themselves and everyone else. And they are preparing to do something about it.
