This is a very interesting discussion, and I feel like I'm learning a lot.
One thing I figured was worth checking was how many bison there were pre-industrialization, and how many cows there are now.
Some quick googling seems to say:
~60,000,000 Bison in North America in 1600
~1,000,967,000 Livestock Cattle worldwide in 2021
