A research group in Australia has determined that, unlike those of sheep and cattle, kangaroo farts don't contain methane, a major contributor to global warming. The kangaroo stomach is host to bacteria that aid digestion, and do so with great efficiency, but don't produce methane as a byproduct. Now, efforts are underway to isolate the bug or bugs responsible and then use them to innoculate the digestive systems of cows and sheep in a bid to reduce greenhouse gas emissions. Another group of Australian scientists have proposed a different solution: raise less beef and lamb and eat more kangaroo meat instead. And, no, it doesn't taste like chicken.
