Cow Belch Tie to Global Warming to Be Studied

<i> Reuters</i>

The Environmental Protection Agency will spend $210,000 on a three-year study to determine the effects of cow belches on global warming.

Three scientists at Washington State University said Friday they will study how much methane gas cows and other cud-chewing animals produce when they belch.

The scientists plan to outfit hundreds of cows with backpacks holding a gas monitor connected to a tube placed near their mouths.

One of the scientists said methane is a key factor in global warming. Livestock produce about 15% of all methane.
