It's not exactly a recent development that cows fart. Any farmer could have told you that. And this story is two years old (although Instapundit just mentioned it, in another context). I direct your attention to it mostly to show you that anything can be made to look Important.

Well, that and the cow.

The spiffy graphic is so surreal, so professional yet so absurd, that I had to check to be sure I was reading the real BBC page, not the Onion or something.
