Faster digestion in kangaroos reduces methane emissions

Animals produce methane during the digestion process - some more than others. Currently, around 20 percent of the world's methane emissions stem from ruminants. If this gas is released into the atmosphere, it aggravates the greenhouse effect and aids global warming. Previous studies revealed that ruminants, which include cows and sheep, release more methane into the environment than kangaroos, for instance - even though the latter also possess a foregut, where bacteria break down the plant fiber
