How Gene Manipulation Could Reduce Cow Farts
Cow gassiness is responsible for approximately 25% of methane emissions in the U.S. Now, researchers have potentially found a way to reduce global gas emissions using microbes native to cows’ guts
With every cow fart or burp, methane gas is released into the atmosphere. Methane is a greenhouse gas that is more potent than carbon dioxide. While each individual excretion of cow gas may seem inconsequential, there are more than 1.4 billion cows in the world today according to the U.N., so each little burp adds up. The U.S. Environmental Protection Agency states that approximately 25% of methane emissions in the U.S. come from cows.
The study, published earlier this month examined more than 1,000 cows from Italy, the U.K., Finland, and Sweden.
