What you can do to help

As we celebrate Earth Day's 37th year on April 22, WWF challenges everyone to try some of these small changes to make a big difference. You'll be amazed how easy it is.

1. Don't leave the water running. Turn off the water when brushing your teeth or washing the car. Fresh water is one of our most precious natural resources.

2. Flick off the light when you leave the room. Power plants burn fuels to create energy for your light bulb. Burning fuel makes smog that pollutes the atmosphere and adds to global warming. The less energy you use the less they need to make, and you'll save on your energy bill.

3. Print on both sides of the page at work. It's easy to change your printer settings - you'll use half the paper and save trees.

4. Wash your clothes in warm or cold water. It works just as well as hot in your washing machine and cuts back on energy use.

5. Ditch the paper cups. Bring in a glass to keep at work instead of using the paper ones by the water cooler.

6. Use the right settings on your appliances. Many appliances, like your dishwasher and refrigerator, come with energy-saving settings. Make sure they're turned on.

7. Turn off your computer at the end of the day. A monitor left on overnight uses enough energy to print 5,300 copies.

8. Give your loose change to an environmental charity. After checkout at the supermarket, instead of tossing the coins into your pocket drop them into a Coinstar Center® to donate to WWF. Just select the "donate" option from the menu and choose WWF as the charity. There's probably a machine right in the store so it's an easy stop on your way out.

9. Look at the labels. Take the paper items with the "recycled" emblem over the ones without or look for the Energy Star symbol when buying new appliances.

10. Sign up for an e-newsletter. Get updates on conservation issues and solutions emailed to you and glance through at your leisure.
