Pull my hoof

What's the difference between this from the UK:

Scientists are examining cow farts and burps in a novel bid to combat global warming.

Experts said the slow digestive system of cows makes them a key producer of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide.

and this from America:

BUENOS AIRES - Argentine scientists are taking a novel approach to studying global warming -- strapping plastic tanks to the backs of cows to collect their burps.

Researchers say the slow digestive system of cows makes them a producer of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide in efforts to fight global warming.

Obviously they are the same story, with a few edits*. But one edit is of such scientific importance that its exclusion - if that is indeed what happened - is nothing short of journalistic fraud: there are no farts in the American version. Not one. No one-cheek-sneaks. No SBDs. Not a single barking spider nor a slice of old cheese nor a gambled-and-lost.

American journalists never leave important facts out of a story**, and whether this methane that is destroying the planet comes out of the front end of the cow exclusively or out of both ends is an important fact. There are important scientists spending important money to attach inflatable toys to cows, and they need to know whether those toys require one tube or two. No way would they edit out such a critical piece of information.

Which all makes me wonder: Are the Brits making the fart part up? Did some editor think it would be really funny to sneak in the idea that animals fart? A lot? And it's destroying the earth?

If they did, maybe there is hope for England after all.
