Why can't we delete stuff?

I'll just edit instead!

I know you said that we shouldn’t say humans but I’m gonna say it anyway:

Humans.

Sorry.

Would be interesting to tally up the negative impacts of removing humans as well.

Culls of invasive species would no longer occur, which would be detrimental in those ecosystems.

A fairly significant number of endangered animals probably only exist today due to human intervention and breeding programs (i am well aware that we probably made them endangered in the first place)

Cross breeds would be done as well, Ligers and Mules require humans for breeding. Although in fairness they are definitely not natural to begin with.

Many animals we have domesticated would be done for as well, most smaller dogs are completely, reliant on humans for food and grooming. Many cats would be okay, but some breeds are likely dead ends as well. Jersey cows would probably have a bad time as well, without milking, sheep might have issues as well?

Interesting thought experiment.

Yeah, this is a good topic. I can add a few:

Short term, pets in houses, farm animals, etc will need to escape and start fending for themselves otherwise they'll starve (or dehydrate).. Oops, I'd somehow missed an entire paragraph of your post πŸ€¦β€β™‚οΈ Sheep need us to trim their wool, because we've bred them up grow fair more than they need. They'll get too hot if they don't have problems with defecation first (an actual thing farmers have to worry about).

Medium to long term, when dams and dikes aren't maintained they'll eventually fail, flooding vast areas including the Netherlands.

I guess that the world will continue heating for a bit even once we're gone, so we wouldn't be around to theoretically use our tech to help. Obviously, we're the reason it's happening in the first place, but nature's not equipped to deal with change that's this rapid.

Yes, most of those we created through breeding, but you could argue that wolves and coyotes created modern deer the same way.

I do wonder if many would go extinct in the medium term from predation, before they can evolve fast enough to adapt; I'm thinking farm pigs and chickens would be OK in the short term - they don't need us to survive - but wild dogs/coyotes/wolves, large cats like the NA lions, raptors, foxes... they'd all be putting a lot of pressure on those mostly defenseless breeds. Pigs are not wild hogs. Cattle and horses exist just fine in their environments without humans. Even with predation, herds are large and they aren't defenseless.

Sheep are an exception; like you said, they need us to perform maintenance because of how we've bred them. Are there others?

My thoughts go to a lot of our stored and operational fuel supplies. Nuclear fuel (both civil and weapon) would eventually become exposed through lack of storage container maintinance and cooling starting meltdown reactions in their localized environments. Oil extraction, distribution, and refining systems are automated to an extent but somewhere a tank is going ng to rupture or just run out of space and then it's all getting into the environment, likely at sea to have what effects that may cause.

Life After people. Whole series exploring this

Ooh, thanks for the suggestion. Seems its on youtube as well. Thanks!

Was this the one with flying cats? Because that show was SO GOOD!! Except for the first few minutes with the dog...

Good point! Within a few weeks billions of animals would die. Chicken, pigs, cows, cats and dogs.

We definitely need to clarify what "good for the planet" means if we want to decide on the best answer.

Humans are the only species that would ask a question like this with ecologically damning effects. So, yeah.

I'm going to provide one very important reasons it would be disastrous to the ecosystem if humans were suddenly deleted from the Earth: what happens to the many currently active nuclear reactors? And what happens when Chernobyl's sarcophagus finally corrodes entirely and exposes that radioactive blight to the entirety of Europe and central Asia? Probably nothing good is the answer.

I would be willing to put money on "likely nothing" being the answer for active nuclear reactors. They're highly automated from a safety perspective these days. I'd be more worried about chemical plants

That's a good point, too. My general idea was we have certain things we've created that we can't leave unchecked or else it might be disastrous for the environment. Human infrastructure expects humans to exist.

Humans are not the problem. Ultrarich people are.
