What’s outrageous is that the government charges ranchers a pittance to graze cattle on public lands, far less that the market rate for grazing on private land.
To be fair, for a lot of public land the alternative to being grazed would be being on fire.
In a wet year that kind of place looks pretty lush but in a dry year it is hard to believe cattle can survive. People can argue forever about what the carrying capacity is because the answer is "it depends".
