Like, we’re destroying the one place we know is a sure bet on where we can prosper if we keep it healthy, but instead the world’s richest man is trying to expand to other planets while this one’s ability to sustain life is in jeopardy. IMO that makes us potentially a very stupid species compared to a species that doesn’t really care about meeting other aliens because they value the life on their own planet far more than we do.
you wouldn’t know that. deep-sea life would probably survive any gamma ray burst, i guess.
and it turns out, there’s a surprising amount of deep-sea life: bacteria and complex life.
on this diagram, it would throw us back by 300 mio. years max.
Won’t ocean acidification kill a lot of that life? Isn’t it already?
