Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Don't think I need to summarize this one. This is bad news for everyone.

Humanity will be just another dead branch on the tree of life

[–] TeoTwawki@lemmy.world 1 points 15 hours ago* (last edited 15 hours ago)

at least its self-pruning

Humans 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.

Humanity is the only species capable of the arrogance required to believe we deserve to endure. Our survival instincts are ultimately self-defeating because we refuse to evolve socially. Instead we make wars and loot resources, rinse and repeat.

[–] 13esq@lemmy.world 1 points 4 hours ago

Right. We survived the ice age with stone age tech.

Not saying that this makes any of this OK but resilience is absolutely one of humanities highest spec traits.

I thought it was 500. I think I even read that 50 might be enough by some estimates.

[–] Danquebec@sh.itjust.works 2 points 10 hours ago* (last edited 10 hours ago)

50 if you're carefully planning breeding.

2000 for a good chance to persist long-time under normal breeding conditions

[–] chaogomu@lemmy.world 2 points 16 hours ago

I'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.

When 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.

“There are only nine meals between mankind and anarchy”

[–] CitizenKong@lemmy.world 7 points 1 day ago (1 children)

Yep, 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.

[–] itsonlygeorge@reddthat.com 3 points 1 day ago (2 children)

How much can you forage in the bush’s of human civilization? Not much grows in abandoned cites.

[–] CitizenKong@lemmy.world 10 points 1 day ago

Nature reclaims cities pretty quickly though.

[–] dual_sport_dork@lemmy.world 6 points 1 day ago

Even now cities cover a tiny fraction of the surface, and they're already full of squirrels, rats, and pigeons.
