Argentine scientists are taking a novel approach to studying global warming - strapping plastic tanks to the backs of cows to collect their burps and farts.
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.
Scientists around the world are studying the amount of methane in gas expelled by cows and Argentine researchers have come up with a unique way to collect and analyse it.
They attached red plastic tanks to the cows’ backs and connected them through a tube to their stomachs, which trapped the gas.
‘When we got the first results, we were surprised. Thirty per cent of Argentina’s (total greenhouse) emissions could be generated by cows,’ said Guillermo Berra, a researcher at the National Institute of Agricultural Technology.
