    Meh, this only covers some mass extinction events - not all of them. Not even most of them, in fact, which remain in the world of supervolcanos, meteorite impact, and general Oh Shit It’s All Gone Pear-Shaped-type events.

    Cheery thought, though, that we’re all screwed in 10 million years anyway.
