Confederation and meat consumption

[xise]

Really the whole vegan vegetarian meat-eating debate is going to be largely academic as the world population continues to increase due to the sheer environmental inefficiency and damage animal agriculture (even vegetarianism) causes. (Insert multiple articles here about how animal agriculture increases CO2 emissions per individual by +40% and increases land use by 3x+ what is needed for plant-based calories. Not even that controversial these days though the studies aren't widely known).

Simple efficiency will require land to be used for plant-based diet as opposed to animal farming, with minute amounts of sustainably hunted land animals that thrive in unfarmable land, and a small amount of sustainably fished seafood from the ocean. I think 200 years from now, everyone will basically be getting 98+% of their calories from plants just by virtue of existing on a planet that is getting close to max human population. Barring lab-created food, of course.
