Landscapes grazed by human protected food animals are not much more "natural" than farmed landscapes. The grazing density of cattle, sheep, and goats is much higher than natural grazers and alters the ecosystems dramatically. This is mostly due to the lack of predators, which would cause the herds to move more often and have lower density. Wilderness landscapes can also have this problem when apex predators are removed and grazers eat and breed in peace. See Yellowstone and the reintroduction of the wolf.
