Memes aside raising livestock is fucking terrible for the environment and is roughly 10% as efficient as growing crops due to the base 10 rule of the ecology pyramid. Methane from farts and decomposing shit is a much more potent greenhouse gas than CO2. Cattle spread disease, specifically antibiotic resistant disease, like a motherfucker due to the fact that antibiotics are literally chopped into the feed and from how tightly packed they are in factory farms. Not to mention the fact that we feed them corn which is unnatural and just asking for some awful infections.
There is literally nothing about factory raising livestock that is okay, but because we have so many goddamn people it isn't economically feasible to raise only free range, grass fed beef. Meat prices would skyrocket.
