In this video:
There are currently approximately 1.3 to 1.5 billion cows grazing, sleeping, and chewing their cud at any given time on planet Earth. And these 1,300 pound (average weight for both a beef and dairy cow) animals eat a lot. Much like humans, when they eat, gas builds up inside of their guts and has to be expelled. (See Why Beans Make You Fart) Cows fart and burp… a lot. The result is a large amount of methane being introduced into the atmosphere.
