Cows and global warming
It is no wonder that cows are one of the main contributors to the hole in the ozone layer with all its grazing and many stomachs. Apart from CFC, the biggest culprit is hydrocarbon emissions from cars and cows. Yes, cows! Cows release some 100 million tons of hydrocarbon annually – by releasing gas. To give you an idea of how much gas a cow emits: if the gas of 10 cows could be captured, it would provide heating for a small house for a year. But unlike what you think, cows release hydrocarbon mostly by burping.
