The scale of animal agriculture now is a result of not dealing with the issue then, since it was large landlord farms depopulating the countryside for sheep. Ranches and feedlots are the metabolic rift in its starkest form so I'd gladly return to night soil if it meant downscaling to sustainable farming levels. That's conserving as much energy as possible collectively in the most useful way.
