I was just reusing the term op used. And that’s a tiny percentage if the trade off is keeping humans fed.

No, it's a huge amount relative to the nutrition it actually provides. There is so much terrible (by any metric apart from maybe direct monetary cost) meat consumed and there are vested interests in a lot of industries to maintain that status quo.

Don't get me wrong, good meat is delicious and there are plenty of ecosystems that require grazing and large herbivores to maintain, but the current system is devastating and doesn't provide nearly as much nutrition to the end user as it consumes in its production.
