Scientists in Mexico say they may have found a way to cut the production of methane, a gas linked to rising temperatures on the Earth’s surface. The scient ists say their method may help reduce the methane released by cows, one of the main producers of the gas.

When talking about global warming, many people think of carbon dioxide, another heat-trapping gas. Methane is an even more powerful heat-trapping gas. Cows are known to produce high levels of methane when they eat and process food.

Researchers at the Autonomous University of the State of Mexico are studying how a cow’s diet affects the production of methane. The researchers are using a specially designed machine to measure the effect. The scientists use the machine to try to capture the animal’s breathing to examine the methane released.
