(Newser) – Cow belches have been called a bigger environmental threat than cars and trucks—and now dairy groups are taking steps to keep dangerous burps to a minimum, the New York Times reports. One Vermont farmer has seen his cows’ methane emissions drop 18% after boosting the alfalfa and flaxseed in their feed, while methane has plummeted some 30% in France, where industrial farms are using alternative feed.

The Vermont farmer—one of 15 taking part in a pilot program being run by the Stonyfield Farms yogurt company—says the feed change hasn’t hurt milk production, and his cows are “healthier and happier.” They have better breath, too. A French firm is working with Stonyfield to expand the pilot program in the US.
