1. CHANGE YOUR LIGHT
If every household in the United State replaced one regular lightbulb with one of those new compact fluorescent bulbs, the pollution reduction would be equivalent to removing one million cars from the road.

2. TURN OFF COMPUTERS AT NIGHT
By turning off your computer instead of leaving it in sleep mode, you can save 40 watt-hours per day. That adds up to 4 cents a day, or $14 per year.

3. DON'T RINSE
Skip rinsing dishes before using your dishwasher and save up to 20 gallons of water each load.

4. DO NOT PRE-HEAT THE OVEN
Unless you are making bread or pastries of some sort, don't pre-heat the oven. Just turn it on when you put the dish in. Also, when checking on your food, look through the oven window instead of opening the door.

5. RECYCLE GLASS
Recycled glass reduces related air pollution by 20 percent and related water pollution by 50 percent. If it isn't recycled it can take a million years to decompose.

6. HANG DRY
Get a clothesline or rack to dry your clothes by the air. Your wardrobe will maintain color and fit, and you'll save money.

7. GO VEGGIE ONCE A WEEK
One less meat-based meal a week helps the planet and your diet. For example: It requires 2,500 gallons of water to produce one pound of beef. You will also also save some trees. For each hamburger that originated from animals raised on rainforest land, approximately 55 square feet of forest have been destroyed.

8. WASH IN COLD OR WARM
If all the households in the U.S. switched from hot-hot cycle to warm-cold, we could save the energy comparable to 100,000 barrels of oil a day.Only launder when you have a full load.

9. USE BOTH SIDES OF PAPER
American businesses throw away 21 million tons of paper every year, equal to 175 pounds per office worker. For a quick and easy way to halve this, set your printer's default option to print double-sided (duplex printing). And when you're finished with your documents, don't forget to take them to the recycling bin.

10. RECYCLE NEWSPAPER
There are 63 million newspapers printed each day in the U.S. Of these, 44 million, or about 69%, of them will be thrown away. Recycling just the Sunday papers would save more than half a million trees every week.

11. BRUSH WITHOUT RUNNING
You've heard this one before, but maybe you still do it. You'll conserve up to five gallons per day if you stop. Daily savings in the U.S. alone could add up to 1.5 billion gallons.

12. SHOWER WITH YOUR PARTNER
Sneak in a shower with your loved one to start the day with some zest that doesn't come in a bar. Not only have you made a wise choice for the environment, but you may notice some other added...um...benefits.

13. ADJUST YOUR THERMOSTAT
Adjust your thermostat one degree higher in the summer and one degree cooler in the winter. Each degree celsius less will save about 10% on your energy use! In addition, invest in a programmable thermostat which allows you to regulate temperature based on the times you are at home or away.

14. RECYCLE OLD CELL PHONES
The average cell phone lasts around 18 months, which means 130 million phones will be retired each year. If they go into landfills, the phones and their batteries introduce toxic substances into our environment. There are plenty of reputable programs where you can recycle your phone, many which benefit noble causes.

15. RECYCLE ALUMINUM AND GLASS
Twenty recycled aluminium cans can be made with the energy it takes to manufacture one brand new one.Every ton of glass recycled saves the equivalent of nine gallons of fuel oil needed to make glass from virgin materials.

16. CHOOSE MATCHES OVER LIGHTERS
Most lighters are made out of plastic and filled with butane fuel, both petroleum products. Since most lighters are considered "disposable," over 1.5 billion end up in landfills each year. When choosing matches, pick cardboard over wood. Wood matches come from trees, whereas most cardboard matches are made from recycled paper.

17. SAY NO TO PLASTIC BAGS
Each year the U.S. uses 84 billion plastic bags, a significant portion of the 500 billion used worldwide. They are not biodegradable, and are making their way into our oceans, and subsequently, the food chain. Stronger, reusable bags are an inexpensive and readily available option.

18. PAY BILLS ONLINE
By some estimates, if all households in the U.S. paid their bills online and received electronic statements instead of paper, we'd save 18.5 million trees every year, 2.2 billion tons of carbon dioxide and other greenhouse gases, and 1.7 billion pounds of solid waste.

19. STOP PAPER BANK STATEMENTS
Some banks will pay you a dollar or donate money on your behalf when you cancel the monthly paper statements you get in the mail. If every household took advantage of online bank statements, the money saved could send more than seventeen thousand recent high school graduates to a public university for a year.

20. SHARE!
Take what you've learned, and pass the knowledge on to others. If every person you know could take one small step toward being greener, the collective effort could be phenomenal.
