Blazing Saddles Meets Global Warming

We've uncovered details from the top secret Kyoto II negotiations underway in Europe.

You cannot stop a sheep belching or farting, but you can make sure its eructations are less damaging to the environment.
Belches and, to a far lesser degree, farts from sheep, cows and other farm animals account for around 20% of global methane emissions. The gas is a potent source of global warming because, volume for volume, it traps 23 times as much heat as the more plentiful carbon dioxide.
To protect the planet from such ruminant effusions, a team led by Andre-Denis Wright of the Commonwealth Scientific and Industrial Research Organisation in Perth, Western Australia, has developed a vaccine against the archaean microbes that produce methane in sheep rumens

Too bad that vaccine wasn't available for this infamous campfire meeting.
