I laugh when EPA wanted to tax ranchers for the number of cattle they have. Reason is the methane they released in to the air. Last time i checked, there where over 80 million bison in North America. We dont have nearly 5 million cattle in North America.
Ironically I googled this. There was an estimated 60 to 80 million Bison at one time back int the 1800s or sometime arou0nd that period. Now there is around 350,000 bison on the open range. Which is up from the low 100s. Another site said there were 500,000 bison being raised for food.
The EPA is one of the most abusive agencies. Lot of scandals going on with them.
