but rarely the only option. Unless you do crazy things, there is more land suitable for grazing only, than not. And doing crazy things makes zero sense in the context of this conversation, which was about how cattle are all some land is good for. Your argument seems to boil down to "well, we could literally move mountains of dirt, or perform massive terraforming projects on useless soil!," well of course, and so what. It doesn't make you correct, because this sort of discussion is senseless in the context we were discussing. Take the soil example, yes it would be billions per 100 acres, because on that scale (the Canadian shield) you'd either have to desoil massive amounts of usable farmless, or start grinding rock and creating new topsoil from that... so current market prices are meaningless! And if you were going to do that, why not just proclaim that the sahara is perfect farmland too, but of course you'd have to dig irrigation ditches, setup trillion dollar desalination plants, but hey I'm sure you'd chime in too, when someone says desert sand isn't good cropland too?!?!? No buddy, desert isn't good for growing corn. (I can hear you... But! But, you only have to...)

Nobody is grazing cattle in the Sahara. They did graze it next to their which is one of the reasons it’s expanded so far. That said, farmers are actually reclaiming land at the borders from the desert which isn’t possible with herding, in other words much of this land is only viable for farming. Your 50% benchmark in terms of land is really not a function of each individual acre of land on it’s own. The southwest as a whole needs vastly more irrigation than is available, but which specific bit of land becomes farmland and which but is used to graze cattle is very arbitrary. The parts that do grow crops generally have more to do with water rights and which bits are federal land than the actual land it’s self. Conversely a lot of US farmland is more sustainable for grazing, but the giant aquifer is a temporary solution.

PS: Just to add. Take the soil example, yes it would be billions per 100 acres, because on that scale (the Canadian shield) you'd either have to desoil massive amounts of usable farmless, or start grinding rock and creating new topsoil from that... so current market prices are meaningless! Individual large river delta’s contain hundreds of cubic miles of soil. It’s not a limitless supply, but there is plenty of soil though not topsoil to cover 3 million square miles of the Canadian Shield.
