Curbing Greenhouse Gases

An article in the Huffington Post points out that raising the more than 10 billion animals required to feed this carniverous country is a major contributor to global warming (source). According to the article, if we all go vegetarian, it would reduce emissions more than if we all started driving a hybrid car. Water pollution, land degradation, and grain overuse are other potent side-effects of the american diet. For those of us interested in sustainability, going at least mostly vegetarian seems to be an important "wedge" towards curbing greenhouse gas emissions.
