This article talks about how kangaroos were once thought to have unique stomach bacteria that don’t produce much methane gas when they break down the plants they eat. Updated research however shows that is not the case. Kangaroos produce about as much methane as horses and other animals of their size. Although it is still less than cows. It is important to note that while it is less abundant that carbon dioxide, it has about a 25 times stronger potential to trap heat energy. Cows produce about 200 liters of methane a day, and there are around 1.4 billion cows worldwide. I’ll let Hayden come up with a way to lower those emissions.
