Seafood, though I didn't mention it in my post, isn't all that much better.

To get tuna or salmon (most commonly consumed fish in US) there are usually 100+ other fish that are caught in the fishers nets who died and get thrown back into the sea dead.

But slightly better given that the fish aren't always prevented from living their normal lives before being caught, killed and eaten.

And aren't there other ways to get protein? Even lots of it?
