Amount of methane emitted is linked to how fast food moves through the grazers’ guts, researchers suspect
Kangaroos do blow farts spiked with methane.
More methane is escaping the behinds of kangaroos than previously thought, an international group of researchers reports online November 4 in the Journal of Experimental Biology. It’s still less than many other grazing animals, though, the researchers say. They think that microbe populations haven’t reached a stage of their life cycle during which they produce a lot of methane, helping to keep the animal’s gassy emissions down.
Knowledge about how methane — a greenhouse gas contributing to global warming — is produced in kangaroos could have implications for curbing the significant amount of methane emitted each year by farm animals like cattle.
Kangaroo toots have been considered easy on the environment because they’ve been thought to contain little to no methane. But Adam Munn, a wildlife biologist at the University
