Kangaroo gut microbes make eco-friendly farts

Studying marsupials’ low-methane gas could help researchers lower livestock emissions

When kangaroos let one rip, the gas may be offensive to the nose but easy on the planet.

Marsupial toots and burps contain little or no methane, a potent greenhouse gas.
