10 cows in Argentina are wearing fashionable pink ‘balloon backpacks’ that collect methane directly from their stomachs. Researchers in Argentina are studying the effects of methane on the environment, and they’ve discovered that methane from cows accounts for more than 30 percent of Argentina’s total greenhouse gas emissions.
From The Telegraph:
As one of the world’s biggest beef producers, Argentina has more than 55 million cows grazing in its famed Pampas grasslands.
Guillermo Berra, a researcher at the National Institute of Agricultural Technology, said every cow produces between 8000 to 1,000 litres of emissions every day.Methane, which is also released from landfills, coal mines and leaking gas pipes, is 23 times more effective at trapping heat in the atmosphere than carbon dioxide.
Scientists are now carrying out trials of new diets designed to improve cows’s digestion and hopefully reduce global warming. Silvia Valtorta, of the National Council of Scientific and Technical Investigations, said that by feeding cows clover and alfalfa instead of grain “you can reduce methane emissions by 25 percent”.
So, these big balloon-like bags collect the methane that would otherwise come out of the cow at both ends and end up in the atmosphere, and when they’re full the scientists take them off and hang them up in the corral for analysis. Gross. Can you imagine accidentally getting a whiff of methane straight from a cow’s stomach? Though, I guess it may be milder than it would be after traveling through… okay, I’m thinking way too much about cow flatulence first thing in the morning.
