> societies relying a lot on animals, so having a lot of fertilizer as a byproduct
Animals also eat. There was never an abundance of fertilizer before industrial processes.

I'm curious: what do you think they were eating?
Livestock was and is used to convert plants humans can't eat into milk and meat that we can. Even modern grass-finished beef is raised mostly eating grasses. Grains are really expensive compared to some grass growing in a field. I don't understand why people think it would be even close to economical for a rancher to raise an animal over 1000 pounds on grain alone. That beef would be more expensive than any wagyu.
