Cows are responsible for 25% of the methane produced on planet Earth. That’s so much greenhouse gas that even the United States has called for a reduction in cow emissions by 2020. Argentina’s National Institute for Agricultural Technology may have the answer: cow “fartpacks,” large plastic bags attached to the back of a cow like a backpack. They’re connected to a tube that you ram up the cow’s butt into its digestive tract. The fartpack can extract 300 liters of methane a day from a typical cow and then they plan to use that gas by turning it into energy.
