I’m open to any answer in this; but I think he misses the point here that every animal in itself would need a field of grass in food volume to survive.
No matter how you put it, it seems to me that adding an extra animal to the equation requires more food/water/space, not less.
When you’re adding a cow to an existing wild field, the field and its inhabitants don’t disappear. When you start planting crops in that field, you destroy the whole associated ecosystem.
