More evidence for overpopulation being the problem:
Is there more flatulence in a vegetarian diet?
Suffice it to say that flatulence is a common complaint among and about vegans, and for that matter vegetarians generally. (For those of you who don't know many vegetarians, they come in various flavors; vegans are the most hard-core, eschewing not only meat but animal products of any kind, including milk and eggs.) The problem is the body's inability to fully digest the complex carbohydrates so abundant in the vegetarian diet and the consequent excessive production of gases such as hydrogen, carbon dioxide, and methane.
So vegetarianism is really shifting methane and CO2 emissions from the cow's ass to a human's ass?
