We don't need to use that land though. If we're not feeding livestock then we don't need near as many crops to support ourselves so let the unusable land return to the wild. Also if you want to use scrub land to feed your livestock you're going to need a lot of it like in Australia. >For millennia, humans raised livestock on pasturing lands, seemingly without harming the environment too badly. For millennia most people wouldn't be getting access to 200lbs of meat a year. There was also a lot fewer of us to feed that much meat to.
