Nearly all animals burp and fart. Kangaroos, however, are special. The gas they pass is easy on the planet. Some might even call it “green” because it contains less methane than emissions from other grass grazers, such as cows and goats. Scientists now credit the ‘roos low-methane toots to the bacteria living inside their digestive tracts.

 

These researchers hope their new finding could lead to tips for cutting methane emissions from farm animals.
