Things you can do

suggested by the World Wildlife Fund

You can help stop global warming by taking these 10 steps to cut your yearly emissions of carbon dioxiude by thousands of pounds.

1. Next time you buy a car, choose one that gets at least 30 miles per gallon (reduces carbon dioxide 2,500 pounds a year over a car that gets 10 mpg less).

2. Where you can, choose an electric utility company that does not produce power from polluting sources such as fossil fuels and nuclear fission. (Enormous potential reductions in carbon dioxide emissions.)

3. Replace standard light bulbs with energy-efficient fluorescents. (Reduces emissions by 500 pounds per year per light bulb.)

4. Replace worn-out home appliances with energy-efficient models. (Reduces emissions by up to 3,000 pounds per year.)

5. Choose the best energy-saving models when you replace windows. (Reduces emissions up to 10,000 pounds per year.)

6. Wrap your water heater in an insulating jacket. (Reduces emissions up to 1,000 pounds per year.)

7. Install low-flow showerheads that use less water. (Reduces emissions up to 300 pounds per year.)

8. Ask your utility company for a home energy audit to pinpoint the biggest energy-wasters. (Potential reduction of thousands of pounds per year.)

9. Whenever possible, walk, bike, carpool or use mass transit. (Reduces emissions by 20 pounds for every gallon of gasoline not used.)

10. Insulate walls and ceilings and save about 25 percent of home heating bills. (And reduce emissions by up to 2,000 pounds per year.)
