Well ignoring your dumbass comment I responded to, simple a lot of livestock is less intensive to maintain than farmland and can even be better than not doing it. The city and county in my area rent cattle to keep brush down. The problem most vegans have with livestock raising or even fishing is endemic to all forms of agricultural practices. You know that almpnd milk ya drink, yeah its probably helping make water more scarce here in California. Meanwhile I can get milk from a dairy a bit away from my house where the cows eat brush and drink water from the ranches water collection system.
The name of the game is harm reduction, while industrial farming generally sucks for the animals it is improving over time (at least here in California, fuck if I know what Utahs foing). Lots of Vegan shit is worse for the environment cause of water usage alone let alone shipping.
Oh and also, lots of farms exploit labor and guess what it takes a lot more labor to raise fucking beans than it does cows, goats, or swine.
Mind you I dont go out my way to eat needlessy wasteful animal products (lookin at you veel) because im not a complete asshole. I follow my ancestors philosophy, give it a long life good then slaughter it gets ya more and better quality meat.
