Cows release significant amounts of methane daily, which contributes to global warming. A single cow produces approximately 214kg of methane per year, or 58g per day. Globally, the 1.3 billion cows release around 760 million kg of methane daily. Methane is a potent greenhouse gas that is 23 times more effective at trapping heat than carbon dioxide. While the methane from cows does not directly harm nearby animals, it does impact the environment by contributing to climate change. Some methods to reduce methane from cows include changing their diets or capturing methane from cow manure.
