Right now I can see how the website has died out.
I've read just somewhere that if we're in the middle of max extinction, we should be worrying about coyotes and pigeons, not about elephants and tigers.
If we're not we're probably not there yet.

- kbutler 9y agoMedium-large animal extinctions are well-documented, primarily because of predation and introduction of invasive species. This is largely complete, as cats and rats and people are pretty much everywhere now. The vast majority of the 100-1000x baseline extinctions are hypothesized: we estimate that richly biodiverse areas hold N unknown species per area M. We have destroyed M' area, therefore estimate N' species are now extinct. I have been able to find no actual evidence of such extinctions. The mass extinctions in the Paleo record are driven by more significant disruptions of the base ecology - bees are probably the most vulnerable foundation species talked about now.
