Where are you getting those numbers from? The EPA has agriculture at 10% of US green house gas emissions. A quarter of that (so close to your 2% number) is from methane emissions alone. If you stop farming animals you're also looking at reduced emissions from not using manure and growing less crops since you don't need to make feed.

And it's not just the greenhouse gas emissions. 1 oz of beef takes over 100 gallons of water to produce. In comparison broccoli takes about 2 gallons per oz. In terms of calories beef requires 7.25 times more water.

I don’t know anymore, sorry. It was some years ago in a study made by some German or Swiss scientists that was locked behind a paywall.
I’ll have a look at the sci-hub and drop the link if I’ll ever find it!

It was a very in-depth study also included mountainous regions where agriculture is not possible, the cows eat that grass and the waste of vegetables like husks and stems and stuff like that.
