The takeaway being we should eat more king crab? That's the kind of activism I can get behind!

No, the takeaway is that we are abusing the ocean causing ecosystem collapse.

A takeaway needs to be actionable. That's kinda the whole point. If there are too many king crabs, we can action on that by making their removal economically favorable.

I'd be curious to hear what the people downvoting my comments think the author was implying in their comment, which so far as I can tell is saying the exact same as mine just less bluntly.

A takeway just needs to be memorable. Actionable is nice, but not a requirement. "We can't do anything useful in this situation" can be a valid takeaway, as can "we do not know enough at this point."

In this situation, my takeaway is that we do not know enough, and that's what I understood the parent's post to be saying.

Removing the surplus crabs might help, it might set off another chain of poorly understood events.
