greenhouse gas

Cow guts are quite the factory. Grass goes in, microbes help break it down and make hydrogen, then other microbes start converting it to another gas. In the end, you get methane, manure and meat.

One of those things is not like the other. Methane emissions are considered the second-worst greenhouse gas after carbon dioxide, according to Stanford University professor Rob Jackson.
