Scientists to make cows fart like kangaroos

Cow farts contain methane, a greenhouse gas. Kangaroo farts do not. So scientists in Australia are going to transfer intestinal bacteria of kangaroos into cattle and see what happens.
According to the government of Queensland, almost 14% of all greenhouse gas emissions from Australia come from cow farts, so this seemingly silly idea could actually make a big difference.
