Hm, this seems to be missing the point that plant monocrops destroy the soil and are not nearly as efficient a source of food for the human body as fresh animal meat. Regenerative agriculture, which ideally requires both animal and plant cultivation, would be a better path forward if it could scale. If I remember correctly the papers that originally thought cattle were a big contributor to global warming turned out to be pretty incorrect when they were re-examined as well
