The University of New Hampshire has won a $700,000 to grant to study greenhouse gas emissions from organic dairies, which are cause by cow burps, among other things.
The report says that cows emit most of their methane through belching. Only a small fraction is from flatulence. That must be why the report says, Beano probably isn't an option.
So there ya have it -- the government is spending $700,000 to study cow burps.
