Agriculture is responsible for an estimated 14 percent of the world's greenhouse gases. A significant portion of these emissions come from methane, which, in terms of its contribution to global warming, is 23 times more powerful than carbon dioxide. The U.S. Food and Agriculture Organization says that agricultural methane output could increase by 60 percent by 2030. The world's 1.5 billion cows and billions of other grazing animals emit dozens of polluting gases, including lots of methane. Two-thirds of all ammonia comes from cows. Cows emit a massive amount of methane through belching, with a lesser amount through flatulence. Statistics vary regarding how much methane the average dairy cow expels. Some experts say 100 liters to 200 liters a day (or about 26 gallons to about 53 gallons), while others say it's up to 500 liters (about 132 gallons) a day. In any case, that's a lot of methane, an amount comparable to the pollution produced by a car in a day. Mad cows!

I am writing this instead of buying something
The refer is buzzing again. I can hear it through most of the walls of this rental house. This energy compliant model cycles the fans often. Energy compliance makes it good for capitalists to generate revenue. What is also needed is the double pane windows to keep in heat and to stop the earth from melting down and backing up the sewers. Just image the stench We must stop the flooding; hundreds of millions of lives are at stake.
