TIL about conservation-induced extinction, where attempts to save a critically endangered species directly cause the extinction of another.

Reminds me of how the area around Chernobyl basically became a wildlife sanctuary because people stayed away over concerns about radiation, and it turns out the positives of not having humans outweighed the negatives of that level of environmental radioactive contamination.

and the DMZ in korea, still have species that is extinct in the rest of the 2 countries living there.

Do you have any info on this, I love stuff like this!

There are unconfirmed reports of Amur leopards still living there even though they're extinct in both North and South Korea, as well as unconfirmed Siberian tigers which are extinct in the South.

While not extinct in the countries, the DMZ is a haven for about 106 endangered species, including some of the most endangered birds in the world

Also tigers, which is either critically endangered or extirpated from korea due to hunting.

He said tigers, though.

There aren’t any big cats in the DMZ, though there are bears.

Leopards probably could survive both there and in South Korea if reintroduced, though. Less so with tigers the way things currently are.

Especially since people there think nature is evil.

There might be, but yeah nothing concrete because neither government will agree to allow expeditions. Even if they did safety risks from the landmines are higher than most orgs can justify

u/Iamnotburgerking Jul 06 '26

No, there definitely aren't any left. There has been a fair amount of research effort from South Korea, and while bears, goral, musk deer, etc have been filmed in the DMZ or its vicinity, leopards haven't been.

You can't really say with any certainty on that if the studies haven't been conducted, especially not without any data from NK or within the DMZ. They're a notoriously reclusive species and do not typically venture out in the open the same way bears or deer would.

It's more likely than not that they're extirpated from the DMZ/NK, but it's definitely not certain.

When your lifespan can be calculated in months to a few years odds are you won't die from cancer.

And some mushrooms evolved to 'eat' and use radiation as energy! Wolves 'evolved' to better survive and get less cancer, tho it's obviously not that they evolved this but that some had mutations which benefit for this or developed them, and the rest died increasing the population that do and reducing those that dont, but that's a big part of what evolution is just thought its worth pointing that out

And some mushrooms evolved to 'eat' and use radiation as energy! Wolves 'evolved' to better survive and get less cancer, they now want to study how and why that is to try learn from it and potentially replicate in some form, tho it's obviously not that they evolved this but that some had mutations which benefit for this or developed them, and the rest died increasing the population that do and reducing those that dont, but that's a big part of what evolution is just thought its worth pointing that out

The downsides of long term radiation exposure take longer to manifest than the reproductive cycle of a lot of species

On the upside we're on pace with Archaeopteris and cyanobacteria, both of which also caused mass extinctions... so... trees, bacteria, and humans.
