Reminder that farmers can spend something like a dollar per cow per year to allow their cattle to roam through public lands to cause erosion, shit in streams, spread giardia, and give farmers reasons to kill coyotes and wolves.
They surpsingly release most methane through burping, not farting. Even more surprising is that they burp so much methane that it is

The solution to bovine methane emissions is to install a cowalitic converter inside their mufflers. Just like we do with quad udder milk exhaust collectors.
On a serious note i read a while back that they are looking into a type of gut bacteria to give to cows which will significantly reduce the methane produced by the cows digestive system.
This is mostly done in the western U.S. It also takes around 40 acres of land/cow. In drier areas it takes 200 acres per cow.
In an irrigated field, with annual crops, and rotational grazing, we can feed 2-4 cows/acre depending on the location.
We do not need to use 95% of the land we use for pasture.
A 1,200 lb lactating beef animal needs around 3% of it’s body mass every day. So around 35lbs of dry matter forage per day. Works out to around 6.4 tons DM/year.
Under irrigation, In areas without freezing temps, 25tons DM/acre is possible (not easy) or 4 cows. In areas with freezing temps 12-15 tons DM/acre can be accomplished or 2 cows (1 cow if the growing season is short)
10-15" rainfall zone produces around 600lbs DM/acre of which around 50% is available (timing issue) this is around 0.15 tons DM/acre. 6.4 tons DM for one cow is around 43 acres.
In a 5-10" rainfall zone it reduces to under 200lbs DM/acre total. Or 0.05 tons DM/acre or around 128 acres per cow. With that much walking their energy needs increase by as much as 50%. Or around 200 acres/cow.
Guess who grew up on a ranch with BLM grazing ground :-) My grandfather decided going bankrupt was a better than listening to a younger more hotheaded me.
Large heards grazing is necessary for grasslands to thrive.
They till the ground, knock down tall dead plants, graze (but not “browse” the grass), fertilize, and water the grass.
Deer and other fauna do not knock down the grass the way bovine do. We used to have millions of Buffalo. Now we use cattle as a substitute.
If we don’t do that, we have to burn the grassland. Or it dies.
That’s what we used to do in Kansas. It was quite fun. And the government paid us to do it.
Anyways. Here’s some evidence to back up what I’m saying: TED TALK
