The objection I've usually heard is less about farm land being used for pasture instead of growing crops, and more about the amount of crops that have to be grown to feed the cattle... Growing corn to feed cows to feed humans is massively less efficient than growing corn to feed humans, or at least that's how the story goes.
Is there not an efficiency problem there that we could improve on?
