At any given point, after munching and regurgitating grass, tens of millions of Australian cattle, as well as sheep, are belching methane gases nonstop into the air. With methane considered 21 times more potent than carbon dioxide in warming the atmosphere, the burping has given ammunition to environmentalists, vegetarians and other critics of beef while initially putting the large meat industry on the defensive.
Now the industry is fighting back. Along with the government, it is financing a $24 million campaign to reduce burping. Researchers are looking at measures like adjusting diet, managing manure, recalibrating stomach organisms and selectively breeding animals that burp less."The Times goes on to explain:"In other animals known as hindgut fermenters, including humans — in which food is fermented after going through their stomachs — methane is sometimes released through flatulence, a fact that rumen microbiologist Athol Klieve said, has led to misunderstanding about his work.
'We’ve had to put up with that all the time,” Mr. Klieve said. “It comes from the front end! In the cow, it comes from the front end. But if you’re a hindgut fermenter, it goes the other way.'"Imagine that--cows don't fart, they burp. Which, in even simpler terms, they fart through their mouths.Next time you're at a delicatessen, think twice before you order that tongue sandwich.
