Fifty Ways to Help Save the Planet (part 3)

15. Buy Eggs in Cardboard Cartons

Cardboard egg cartons are normally made from recycled paper, which biodegrades relatively quickly, and are also again recyclable—Styrofoam or plastic cartons take a much longer time to biodegrade and their manufacture produces harmful by-products.

16. Drink Shade-Grown Coffee

Shade-grown coffee is for the birds, literally. According to coffeeresearch.org, about 150 species of birds live on shade-grown-coffee farms, while only 20 to 50 inhabit full-sun farms. With increased demand for cheap coffee, many Latin American growers have moved toward full-sun plantations, clearing the habitat of numerous native birds and increasing the use of pesticides and fertilizers. By drinking shade-grown coffee, you can help bird habitats and reduce the need for farming chemicals. Shade-grown coffee beans can be purchased at many grocery stores. Starbucks offers shade-grown coffee as well.

17. Save Water Indoors

A typical American household uses 350 gallons of water each day. About half that—175 gallons—is used indoors (toilets consume about 30 percent of the indoor total). Unnecessary water usage comes in the form of leaks. Fixing leaky faucets and toilets is a quick and easy way to conserve water. A steady faucet drip can waste 20 gallons of water a day. Leaky toilets are even worse, wasting upward of 100 gallons a day. Since toilet leaks are generally silent, check for them regularly by removing the tank cover and adding food coloring. If the toilet is leaking (and 20 percent of them usually are), color will appear in the bowl within 30 minutes.

18. Take Showers, Not Baths

The average American household consumes about 60 gallons of water a day from showers and baths. To reduce this number, take quick showers and install a low-flow showerhead that uses fewer than 2.5 gallons of water per minute, as compared to about 5 gallons with an older showerhead. Baths are relaxing, but it can take 50 gallons of water to fill a tub.

19. Stop the Water

By leaving the water running while you brush your teeth, you can waste 150 gallons of water per month—that's 1,800 gallons a year! Turning the water off while you brush can save several gallons of water per minute. Also pay attention to this water-saving principle while shaving or washing your face.

20. Insulate Your House

Good insulation is one of the best ways to reduce your heating bills and cut your CO2 emissions. Heating and cooling make up 50 to 70 percent of energy use in the average American home. Also, replace old windows and be sure to seal holes and cracks in your house with weather stripping or caulk. A well-insulated house can prevent hundreds of pounds of CO2 emissions per year and can cut your heating and cooling bills by up to 20 percent. For more information, visit eere.energy.gov.

21. Turn Your Thermostat Down One Degree

If you turn your thermostat down by one degree, your heating costs will decrease by about 3 percent. Turn it down five more degrees for four hours a day and reduce your heating bills by almost 6 percent. If you're going to be away for the weekend or out in the evening, turn your thermostat down. It's not true that reducing the temperature means it will take more heat to bring it back up to a warm level (unless you have a heat pump in your home). Also, turn the heat down if you are throwing a party—every guest will be the equivalent of a 100-watt heater.

22. Don't Be a Butt Tosser

About 4.5 trillion cigarette butts are littered worldwide each year—making them the most-littered item. The myth that cigarette filters are biodegradable is just that, a myth. Although the filters do eventually decompose, they release harmful chemicals that enter the earth's land and water during the decaying process. There is nothing earth-friendly about the breakdown. If you must smoke, carry a 35-mm. film canister to store your used butts in until you can properly discard them.

23. Don't Just Dump

Envelopes come in huge quantities for free every day. If you are careful when opening letters, you can use the envelopes again by simply putting a label over the original address. This saves money and trees, while reducing waste. Try to re-use jars and plastic containers—for example, when taking your lunch to work. (Doing so prevents waste, and making your food at home is less expensive than the alternative.) Ask your office manager to buy re-usable mesh coffee filters instead of bleached paper ones, which may contain dioxins. They are tree-free and should save your company money
