Environmentalists and the scientific community have long said that going on a plant-based or vegetarian diet is one of the best ways to significantly cut your carbon footprint on the planet. But if going all vegetarian is too tough, start by getting rid of just red meat. A recent research study by Bard College shows red meat requires "28 times more land to produce than pork or chicken," and it also needs "11 times more water." Red meat also adds "five times more climate-warming emissions." So instead of a hamburger, try a turkey burger. Then next time go for a veggie burger.
