Isn't Ambergris still used in luxury fragrances? https://en.wikipedia.org/wiki/Ambergris
Ambergris is a different product that does not involve the killing of the animal necessarily. Needs to mature for several years in the sea after being defecated by the whale.

#53Confirmation bias is a creepy thing sometimes. I was literally asking my Google Home last night what the longest living vertebrate was and it told me the Greenland shark. Had a whole conversation about it over dinner, arguing about how accurate we think these age-establishing methods are. Though the more interesting part of our conversation (I would say) was wondering how ages work out in practice. For example why do…
Proof of the horrors of lockdown. People now have hour long discussions with google over dinner.

Assuming this is true, I recommend everyone start running! If I am regularly running, my resting heart rate at night drops into the upper 30s. During the day sitting down, 45-50. If I haven't been running (for a week or longer) it picks back up in to the mid 40s at night, and around 60 for normal sitting.
You heart might survive, but your joints probably won't. The stress you put on them when running/sporting when young will come back to haunt you later on! Don't ask me how I know :-)
Guess I’ll go for a swim!

#55> The team looked at 28 sharks, most of which had died after being caught in fishing nets as by-catch. Nice job- the shark had done just fine for ~400 years.
Inevitably they must die of something. Probably would be human related with no other predators.
There's a good chance your death will be human-related as well, I guess we better take care of that then.

This is not true, take your time and run in moderation and you'll have no increased risk of joint pain when you get older.

Related: there’s a new documentary on Netflix called Seaspiracy It has some staggering numbers regarding the amount of by-catch caught every day
I was just reading the wikipedia article for ocean sunfish the other day, and apparently they can be up to 90% of the total catch for what are ostensibly swordfish-catching operations in the Mediterranean: https://en.wikipedia.org/wiki/Ocean_sunfish#Human_interactio....

#59What startles me is how much we've changed their environment in that single individual's lifetime. That shark was the equivalent of a human teenager when the industrial revolution started.
Delusions of grandeur notwithstanding, not much it seems.
Other than made it warmer and more acidic, added a bunch of plastic garbage and removed a significant percentage of its inhabitants, yeah I guess not much.

> removed a significant percentage of its inhabitants
I was actually curious if anyone could help answer the following:
(a) how one would define inhabitant (including bacteria?) (b) what the net %age change actually would be given a suitable choice of (a)
