It's just a pity we couldn't figure out how to better coexist with whales.

We know how, but we choose not to. The same goes for most of our ecological problems, really.

If asked the question, most people would choose to, I believe.

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.

We even weigh different kinds of drugs differently. So I'm told.

cod fishing boats used to have to be wary of the catch being so big that it would tip the boat. We have no real frame of reference for what we've already lost.

Of course we do, you just gave an example. In fact if we truly didn't, then there would be no problem.

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.

Warming will kill off most of the systems these animals depend on within 30 years.

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.

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.

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.

Animals do these things. Bears eat berries and then poop out the seeds, complete with fertilizer. It happens up and down the food chain.
