Sorry to be annoying, but if you eat beef you may as well take credit for killing the world. And while beef is the worst factory food offender on the hoof, a vegetarian is estimated to save the world one thousand times more than someone who elects not to drive a car. So if you cannot grow all your own food, at least try a garden. If you must go to a restaurant, and you must be in a sorry city, try one like Quintessence in NYC.
