That is where you are WRONG! Before the white man came along, the buffalo only farted benign water vapor that smelled like fresh cut grass or, in the autumn, pumpkin spice.
Man, get with the sciencey stuff!!!
And there are lots and lots of cows now, unfortunately (although I do eat eggs) including dairy nearly 100 million in the US, approximately 5 x the population of bison in the 1800’s.
