The other point (after intensive monoculture => extensive rotation) is that organic meat production is of necessity extensive. Intensive animal production with nice organic feed pellets doesn't cut it, since intensive rearing causes ill-health and needs antibiotics etc to prop it up. This means intensive animal rearing => extensive a.r. => we all eat less meat. It means more extensive production on land that is less suited to crop production (hills, mountains, moorlands), that the current productivist model has gradually abandoned to become scrub.
