"There are 1.4 billion cows worldwide, each producing 500 litres of methane a day and accounting for 14% of all emissions of the gas."

A cow lets out Methane when it farts.
Cows that consume grass produce more methane than cows on a high-concentrate or high-grain diet. This is because more acetate is produced than proprionate, which gets converted by the methanogens in the rumen to methane gas, which must be expelled through eructation or belching.
Cow emissions, such as methane, can contribute to ozone depletion indirectly by influencing the levels of ozone-depleting substances like chlorine in the atmosphere. However, the impact of cow emissions on ozone depletion is relatively small compared to other human activities like industrial and transportation emissions.
The two main greenhouse gases in cow manure are methane and nitrous oxide. Methane is produced during the digestion process in cows, while nitrous oxide is released during the decomposition of manure. Both gases are potent contributors to global warming and climate change.
The gas emitted from both ends of a cow is methane, which is a dangerous greenhouse gas, twenty-one times more powerful than carbon dioxide. Methane is causing additional global warming. And it's dangerous to stand too close with a cigarette or a naked flame!A cows fart is dangerous as it produces methane gas. Which is contributing to global warming
A cow releases between 70 and 120 kilograms of methane a year.

Methane is separated from cow dung by subjecting the cow dung to a heat source. From there, methane can be used as an energy source for generating electricity on a farm.

Farm animals, such as cows and sheep, expel methane gas during the process of digestion. Methane is a greenhouse gas that contributes to climate change.
They use this cow dung that contains methane in it to make energy.
Cattle and other ruminants produce much more methane in their intestinal gases than humans as the intestinal bacteria digest cellulose. (Most of the gas comes out of the cow's mouth!) Methane is a greenhouse gas and bad for the environment.
