Writing in Nature, professor of biology Chris D. Thomas bemoans the environmental damages caused by human activity. But not to worry, he says. In a few million years, humans will be extinct.
The geological perspective of Terra is bizarrely reassuring. Humans will presumably be gone within a few million years, perhaps sooner. If the past that Novacek describes is a guide to the future, global ecosystem processes will be restored some tens of thousands to a million years after our demise, and new forms of life over the ensuing millions of years will exploit the denuded planet we leave behind. Thirty million years on, things will be back to normal, albeit a very different 'normal' from before. It is good to be optimistic. The problem is living here in the meantime.
Robin Hanson wonders: "Yet if a plague, for example, were to produce this outcome within the next ten years, I'm pretty sure most everyone would see this as a catastrophe of the highest possible order. So how does this become a good thing if it happens in the next million years?"
