minus-square@chaogomu@lemmy.worldlinkfedilinkEnglish28•6 months agoHumans are pretty resilient. Adaptable to any climate, even the mess of a climate we created. Now, I’m not saying that all 8 billion of us will survive. What I’m saying is, the minimum viable genetic population for humans is about 2000 individuals.
minus-squareRandom_Character_AlinkfedilinkEnglish9•6 months agoWhen food runs out for even a portion of those 8 billion, results are gonna be nasty. It’s hard to talk about climate initiatives when 1/3 of the planet is shooting eatch other. In worst case with nukes.
minus-square@CitizenKong@lemmy.worldlinkfedilinkEnglish7•6 months agoYep, there will always be humans as long as there is literally anything we can hunt/forage and eat. If that will resemble what we perceive as civilisation is another question entirely.

minus-square@chaogomu@lemmy.worldlinkfedilinkEnglish2•6 months agoI’ve seen some of the same estimates. I settled on 2K because that’s what is estimated to have survived the To a supervolcano. Or rather the non-African population that survived. Homosapiens in Africa actually did quite well comparatively.
