We're part of nature. If the "us vs them" is at that level now we're fucked
There is a shortage of nature. On top of that, the ecosystems are changing, and once they're gone they're probably not coming back.
We could lose half of the population tomorrow and still, eventually, hit that predicted 10 billion souls -- it would just take a lil longer. If WA and BC turn into chaparral things like Salmon and Snow Crab ain't gonna live there any more, and never live there again.
All I'm saying is if you stop eating cheap sea food we won't have to send underpaid humans to risk their lives to catch them. Put you money where your mouth is
