You must not literally mean nothing, but I still don't understand where the nutrients are supposed to come from if the land is so poor that food crops won't grow, yet there is supposed to be enough nutritious grass for grazing?
- hcarvalhoalves 4y agoOf course I mean figuratively. Humans don’t have a rumen, so our capability of extracting energy from vegetables is much more limited, basically we need starch (grains or tubers). These animals can feed on grass where these nitrogen-intensive crops won’t grow without fertilizers.
