alt Hacker Newsthe article says 20,000 was 10% of the population therefore the population is 180,000.
if "something might happen in the next 60 years to wipe out half the population" counts as making a species endangered, every species on the planet counts as endangered.
Please go ahead and read the criteria for how the species are tagged as endangered. Current status and population numbers can contribute to that tag, but if there are active threats that are going to rapidly affect healthy population numbers, they will still be considered endangered.
The die off is accelerating. Krill shortages (mostly due to commercial fishing) and warming temperatures will ensure it’s not going to take 60 years and that’s what the tag means.
