This isn't entirely unrelated to how many marginal ecosystems are currently being destroyed by domesticated grazing animals, which are typically invasive species that will overpopulate the area either because of lack of predators or because humans are protecting them from predators. This maybe wasn't such a big deal centuries ago when natural forces also placed stronger limits on the size of the human populations in those areas. Nowadays, though, I think we very much have to think about the possibility that, regardless of any romantic notions about traditional ways of life, using livestock to live in places we otherwise couldn't is not something we do to respect nature, it's something we do that's destroying it.
