Do your part for the planet, one day at a time. With hundreds of simple ways to make a big difference, Living Green proves it's easy to lessen your impact on the environment—at home, at the office, and on the go. Unplug that appliance: The average family burns 1,000 kilowatt-hours of electricity on things that are plugged in but turned off. Think before you bite: It takes 600 gallons of water to grow the corn that feeds the cow that produces one 1⁄3-pound hamburger. "Air fresheners" do nothing but pollute your indoor air: Scent your house safely by boiling herbs or citrus slices in a small amount of water. Improve your toilet's efficiency by placing a soda bottle in the tank. It's a great calendar for the eco-minded family.
