Four Ways to Combat Climate Change

• Change all your light bulbs to LED. They cut lighting energy use by more than 80 percent.
• Eat less beef. Beef production has a high ratio of greenhouse gas production to pound of food.
• Walk, bicycle or use mass transit. If you must drive, use an electric or hybrid car.
• Use refillable water bottles. Never buy brands of bottled water that have been shipped across an ocean, such as Fiji or Evian.
