Governments waste a lot of money trying to prove their global warming baloney and I totally agree that finding data these days isn't easy. This is what a Google search pulls up:

"Beef and dairy cattle, along with pigs and other farm animals, contribute roughly 27% of methane emissions in the U.S., according to the EPA. Most of that comes from their belching; livestock manure accounts for an additional 10% of methane emissions."

This just isn't true, but it serves to bolster their progressive narrative and agenda. Any accurate information is censored now because they want to push their fake food on everyone.
