If I'm arguing for anything is that the global food production is probably not sustainable. That doesn't exclude farming, fishing or high-density food-farming (salmon, shrimps etc.). I mean, the number of issues with providing a couple of billion of humans with enough energy and variety in their diet is not insignificant.. A sheep roaming the hills is probably one of the better ways of producing protein..
