Kangaroos don't expel methane in their farts in the same way that most other animals do. While most land animals expell methane from their bodies, Kangaroos have found a way to reuse it.
Instead of expelling the gas into the atmosphere, the body of a Kangaroo will reuse the methane and convert it into energy!
Scientists are hoping to find a way to translate this ability from kangaroos into cows. Cows are one of the biggest sources of the methane that goes in the atmosphere. If their emissions were curbed, it would help fight against climate change!
Now you know. Methane has a very distinct smell. If you're ever in a room with a buddy and a kangaroo and someone cuts the cheese, you'll know who it was right away.
