So, even if we’re in a future form of humanity and all of our present farming methods failed, sowing seeds and harvesting crops would be the first kind of farming to be “restored” or “rediscovered” or whatever, because it’s vastly more efficient, and assuming you’re recovering from some sort of disaster scenario, feeding as many people as quickly as possible would probably be the goal. They’d probably grow rice and soy or something.
Animal farming is really for luxury goods, except in very remote places where crops can’t be grown



The fact is that animals need to be fed, and they are inefficient. Most animals eat plants, so to create 1,000kcal of beef products, for example, it takes 25,000kcal of plant products. Most animal feeds are based on corn or soy, which otherwise could be turned into human food products directly with a 25x efficiency bonus.
I suppose you could make an argument that grass-fed livestock might work, but then I guess an explanation for why grass is growing but other crops aren’t.
My underlying point is that animal protein is inefficient compared to plant protein
