I should have replied "Sustainable ranching is harder than you'd think." I might remove my comments this afternoon, after you've and had a chance to see this apology.
I've worked with ranchers to conserve wildlife, especially apex predators. Indeed, I predict ranching will become a niche source of protein as vat-grown meat comes online (20 years) and taxpayers decide to stop subsidizing it (10 years?). The draughts, draining aquifers, and scourge of wildfires will also make ranching less viable. But I can't guess the timeline of climate change on ranching.
If you've met any (independent) ranchers, you'd see they know their world is coming apart.
