I R SERIUS COW. THIS R SERIUS EXPERIMENT.
Argentine scientists are taking a novel approach to studying global warming - strapping plastic tanks to the backs of cows to collect their burps. Researchers say the slow digestive system of cows makes them a producer of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide in efforts to fight global warming. Attaching a red plastic tank to a cow's back and connecting it through a tube to the animal's stomach, scientists say they can trap bovine burps and analyze them.
