There are more than one billion cows in the world, and cow farming is a large source of methane emissions. This colourless and odourless gas is much more powerful than CO, at warming the earth. Farmers and companies are developing solutions for decreasing cows' methane emissions. In Canada and Brazil, farmers started adding a special ingredient to their animals' feed to reduce cows' methane production. In New Zealand, scientists are working on a vaccine that can cut methane emissions. Rather than stopping methane emissions, a UK company has designed face masks to catch the gas before it is released. The masks will allow cows to continue their normal diet, but will turn methane into CO, and water. They can fit comfortably on the cow's head and can be adjusted to different head sizes. Sensors on the masks can notice when methane comes out of the cow's mouth and provide the percentage of the gas. This information can also be useful for farmers who can use it to identify the early signs of disease. For example, if a cow eats less, but produces more methane than usual, it may have a health problem. It is predicted that the need for beef and dairy products will go up in the coming years. The company developing the methane-catching masks hopes that farmers will start using their invention, which will slow down global warming.
