Among the scientific community, there is a serious debate about a seemingly funny topic: Cow farts…
As it turns out, studies have shown that cows (of course farmed by man so it’s not thier fault) release massive amounts of methane gas into the atmosphere. One California study showed that dairy cows in the area were producing almost 20 pounds (in weight, that’s almost 10 kg) of gas every year, each. That’s a huge, huge amount.
SO where is the science backing this outrageous sounding claim?
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.
Argentine researchers discovered methane from cows accounts for more than 30 per cent of the country’s total greenhouse emissions.
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 studying ways of changing cows’ diets as well as researching medications that might neutralize the conversion of substances to methane gas in the stomach.
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”.
