Number One Air Polluter

What's the number one air polluter in the United States today? Well, according to the Epalog, the official publication of the Environmental Protection Agency, the leading air polluters are burping cows.

According to Epalog, studies have found that "Ten cows burp enough gas in a year to provide for all the space heating, water heating and cooking requirements for a small house."

The study estimated that American cows burp about 50 million tons of hydrocarbons into the atmosphere each year.

Epalog adds: "There presently exists no available technology for controlling these hydro-carbon emissions."
