TL;DR, the physiology is pretty similar to someone filling your lungs with a saline solution, but slower because they’re cold blooded.

When you consider this, that most ocean plastic comes from fishing, and that modern day slavery is heavily present in it (no police on a boat, and hard to escape) I actually have more respect for meat eaters than pescitarians. Don’t eat seafood, folks.

Edit: Oh, bycatch too, and habitat destruction from bottom trawling. I might be missing more; it’s kind of impressive how fucked that industry is.
