    A cow stands in her pen at the National Institute of Agricultural Technology in Castelar, near Buenos Aires. Argentine scientists are taking a novel approach to studying global warming, strapping plastic tanks to the backs of cows to collect methane

    Experts said the slow digestive system of cows makes them a key producer of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide.

    In a bid to understand the impact of the wind produced by cows on global warming, scientists collected gas from their stomachs in plastic tanks attached to their backs.

    The Argentine researchers discovered methane from cows accounts for more than 30 per cent of the country's total greenhouse emissions.
