British students create cow muzzles to keep the air clean

British researchers have created a special device that can partially solve the problem of greenhouse gas emissions.

According to experts, cows account for 14.5% of all gas emissions. Researchers have developed a mask that neutralizes the methane released by cows when they burp. The gas is then converted to water vapor.

Scientists hope that their device will be in demand. Cattle living on Earth release a colossal amount of greenhouse gases into the atmosphere every year. One cow emits 400-500 liters of methane per year. At the same time, the number of such animals on the planet is approximately 1.5 billion. The cow mask was designed by students from the Royal College of Art in England.
