Venting off

"Burping cows and sheep are being targeted by UK scientists to help bring down Britain's soaring levels of greenhouse gas pollution. Experts at the Institute of Grassland and Environmental Research in Aberystwyth say the diet of farmed animals can be changed to make them produce less methane, a more potent global warming gas than carbon dioxide. Farmed ruminant animals are thought to be responsible for up to a quarter of "man-made" methane emissions worldwide though, contrary to common belief, most gas emerges from their front, not rear, ends."
