Why put a number on it? Every number so far has been wrong. Can we agree on the negative impacts of humans on an environment conducive to humanity without putting obviously wrong timings on predictions? I bet your intention is to provoke urgency but to most people it just causes an eye roll because it's not true, whereas the underlying ideas are true.
You have sailed past the point. There were so, so many cod it was hard not to catch a bunch. That isn’t a metric, it’s an indicator that most likely meant vast unseen numbers. The tip of the iceberg is a metaphor for a reason, though it may become an anachronism within our lifetimes.
I think their point is that discounting the time estimates is more a constant shifting of the window of what we expect more than them being de-facto incorrect. They’re more off by degree (e.g. an XX% reduction vs complete extinction) than being worthless. As the example points out a large reduction can be very similar to an annihilation it’s just that we are only used to what we know so we constantly shift what is normal.
Very much agree. It's a pretty common mistake to bundle real information with obviously wrong details and lose credibility. Especially in the eyes of people looking for a reason to discredit the argument.
Evolution of small things like algae and the krill which feed on it and feed the whale is quite fast. Single celled organisms reproduce on the scale of 20 minutes and hold immense amounts of genetic diversity in their populations to facilitate the success of a better adapted line almost immediately. Additionally, they are adept at horizontal gene transfer from other well-adapted organisms.
This would be great news if the whale literally only required krill to survive, but complex megafauna have complex needs, so the ability of krill and other small creatures to evolve is largely irrelevant in a discussion regarding the ability of megafauna to survive. This is especially true if you read TFA and see that the whales already adapt to eat different things as necessary.
It could easily become this fast or even faster, if we would just stop worrying so much about "playing god" and focus instead on getting good at this job. We don't have much time for this either, as AI is on the trajectory to take over that mantle in the next decade or three, whether we like it or not.
But seriously, we may not have much choice. Natural evolution stopped being able to adapt to environmental changes after it created us; genetic engineering is essentially the only way to make biology adaptable enough again.
The next question is which traits to do you choose and the next question is which traits are better, because choices will imply ordering, and then you open a big can of worms that last time killed millions of people. So maybe there's other ways to avoid doom that didn't create doom last time we went down the path.
Unpopular opinion for obvious reasons, but probably the only realistic one apart from just witnessing one extinction after another. Pollution and climate change aint going anywhere until we elevate whole world to the level of say western Europe.
But since we humans are pretty arrogant with our wisdom and lack long term patience, I can see many ways where well-intended meddling can end up in catastrophe overall.
I hope we create whalegemma (similar to dolphingemma) so we can explain to them how to co-exist better with humans (e.g. avoid this area during their whale hunting season, travel to this area if you get sick or tangled in rope).
…while not changing anything about our behavior, you mean. Because we were never ignorant of how to do better; we just couldn’t accept even any inconvenience, any obstacle to our “growth”.

Pick a lane BBC.
But this is great news. Also the fact that whales "transport huge amounts of nutrients across the globe" (linking to [1]) is fascinating. The role of whales in sucking up critters in one place and pooping them out elsewhere being a fundamental dynamic that drives global ocean ecosystems... just chefs kiss
It's not just the BBC, it's the UK as a whole. Miles per hour or deeply entrenched for speeds but for measurements we use meters. The same for weight, we weigh people in stone but we weigh everything else with grams.
I remember reading about whales returning to an area they hadn't been in for decades and people were worried about them eating all the local fish, but in fact their faeces enriched the local ecosystem from the ground up, leading to more fish. It's a bit like the counter-arguments to the lump of labour fallacy.
Apparently they also measurably affect the vertical water mixing. Fish need dissolved oxygen to breathe, so they don't normally venture past the thermocline. And their fins are also vertical, so they don't cause a lot of vertical water movement.
But whales routinely dive deep, and their tail fin is _horizontal_ and it creates powerful updrafts.
Another organism that affects mixing is apparently jellyfish.
We have no real frame of reference for what we've already lost.
The food chain really is sun -> algae -> krill (and sometimes small fish) -> humpback whale
Like what? Emotional support dolphin?

The same goes for most of our ecological problems, really.

Sorry. I couldn’t resist.

Said from a proudly metric country, New Zealand, where everyone knows their weight in kilograms and height in feet and inches.
