I had thought that avoiding nuclear war was the milestone we needed to meet the alienas. But now I think it is dealing with our byproducts. That is something every animal must deal with, even intelligent ones. I have hope. We make it through so many things in the past. But it will be a very different world.

I think that becoming a space-faring civilization will help us let Earth heal itself. We can do it but its complexity will have to be dealt with.

Thinking of the Eocene, if humans survive, we (as well as most if not mammalian species) will become smaller because that gives better surface to mass ratio for shedding excess heat. (Of course that will make deep space adaptation easier as well, but I digress) Likewise though, reptiles will become bigger. Watch out for giant boa constrictors… 😱 !
