Kangaroos & methane gas

“Scientists are trying to find out why kangaroos don’t burp much, in the hope they might be able to lower greenhouse gas emissions.”

So, basically they are trying to figure out how they can use what goes on in a kangaroo’s stomach to reduce the methane causing sheep and cattle farts and belches.

Interesting because this is the first I’ve heard about the non gaseous quality of kangaroos.
