    Efficiency of calorie acquisition is not the same as sustainability though. Culling an overpopulation of deer that keeps a forest from developing or an invasive species that is wreaking havoc on an ecosystem can both be a net positive on the ecosystem and in terms of sequestering carbon. Meanwhile growing crops on former rainforest land is a clear net negative.

    Those are edge cases though of course and with your average store selection, going with plant-based will just about always be more sustainable.

      you have to ask, why are they becoming overpopulated though? And the answer is, because animal ag. Farmers kill the natural predators because they fuck with their animals that we eat.

        The reason those predator species got killed to near extinction is probably a bit more broad and ugly than just concern for lifestock.

        But you’re correct of course that the main reason for the current overpopulation of many non-invasive species is a lack of predators and they should be reintroduced. But that’s also not a thing that can happen from one day to the next, so even in the most optimistic scenarios some degree of human wildlife management still has a purpose.

        Many farmers growing plants for animal feed. Also there are Deer farms that raise deer specifically for the hunting industry.
