This is one of the few comments to mention animal husbandry, and even then obliquely. The only farming mentioned is arable, and just go out and shoot stuff you want to eat something that can run away from you. Maybe it's an artifact of having the right to bear arms ingrained in the psyche that encourages the "well, if we want meat, we'll hunt it", but it comes across as trigger happy weapon obsession by a bunch of city slickers that would only lead to massive wastage of the finite resources.
We already have cattle that near enough *do* come up to humans saying "eat me". What we don't have - certainly in this discussion - are sufficient people stating they are capable of keeping them alive instead of going "ooh, steak!", blazing away and then wondering what to do next with half a ton of dead creature.
