Cattle have bad breath and commonly suffer from severe, chronic flatus generating large amounts of methane, which is a greenhouse gas and a driver of anthropogenic global warming. The greenhouse gas (GHG) emissions from the agricultural sector account for about 25.5% of total global anthropogenic emission. Methane is one of the most important GHGs and it has 21 times more global warming potential than carbon dioxide. Ruminant livestock contributes the major proportion of total agricultural emission of methane. There is an obvious answer to this problem, stop breeding cattle.
