In human daily life is responsible for an estimate 14percent of the world’s greenhouse gases. The emissions come from methane, which contribution to global warming, and it’s more powerful then carbon dioxide. On the other hand, the world’s 1.5 billion cows and billion of other animals emit dozen of polluting gases, it’s includes lots of methane. 2/3 is come from ammonia of cows. Cows emit a massive amount of methane from their belching with the lesser amount through flatulence. Some scientist had say that cows produce 100lt to 200lt a day (or about 26 gallons to about 53 gallons), while other says 500lt per day. Moreover, cows, goats, sheep and several other animals that belong to cause pollute to the atmosphere are called ruminants. Ruminants have 4 stomachs and restore their food in their stomachs instead of intestines, as human do. Ruminants eat food, and belch it as cud and eat again. This effect on atmosphere that stay nearby and it will send to the hold atmosphere that causes pollute of environment. For instance, Britain, cows contribute 3% of overall greenhouse gas emissions and 25 to 30% are come from gases in livestock.
