Fifty Ways to Help Save the Planet (2/2)

(apparso in origine su www.vanityfair.com il 17/04/2006)

26. Buy recycled products

There has to be a market for products made with recycled goods. Support this movement by purchasing recycled goods, you will save virgin materials, conserve energy, and reduce landfill waste. Recycled paper products include toilet paper (which is no longer scratchy, like it used to be), copy paper, paper towels, and tissues. Look for garbage bags and bin liners labeled "recycled plastic", and buy recycled toner cartridges for your fax machines and printers.

27. Plane better

Air travel is currently responsible for 3.5 percent of the global-warming gases from all human activity and is growing fast. Cargo transport by air is increasing by about 7 percent annually and passenger air travel is up in the last few years by between 4 and 7 percent. The impact of air travel is enormous; a round-trip between New York and Los Angeles emits one ton of CO2 per passenger (to determine CO2 emissions for your next flight, go to www.co2.org). Try to limit the number of flights you take. If you're traveling within a country, why not take a train? (Air travel releases at least three times more carbon dioxide into the atmosphere than rail travel does). If you're planning a business trip, consider whether a video linkup or a conference call will suffice.

28. Carbon offsetting

Air traffic is the fastest-growing source of greenhouse-gas emissions, so when you do fly, consult a carbon-offsetting organization such as Climate Care to "carbon-offset" your journey. Climate Care determines your flight's emissions and the cost to offset the CO2. For example, to offset that round-trip flight between New York and Los Angeles, you would pay about $10 to Climate Care, which invests in forestry and energy-efficiency projects. For more information, visit www.climatecare.org.

29. Switch to green power

The leading cause of industrial air pollution is electricity production. According to the American Lung Association, more than 50,000 Americans die each year from air-pollution-related causes. If available, get your electricity from renewable energy sources such as wind, sun, water, and biomass, all of which generate electricity with fewer environmental impacts. With utility companies in 35 states offering green-power pricing plans, around half of all electricity consumers could buy green, yet only half a million do. Does green power cost more? Yes, but barely. For example, New York's Con Edison charges an additional one-half cent per kilowatt-hour for its green-power products. To see if your energy provider offers green-power options, visit www.eere.energy.gov/greenpower.

30. Standby no longer

Electricity "leaks" are no laughing matter. Televisions, video and DVD players, cable boxes, and other electronic equipment found in nearly every American home are wasting huge amounts of energy. When these devices are left on standby (the equivalent of "sleep" mode for computers) they use about 40 percent of their full running power. Every year, the energy wasted in this way is the equivalent of the annual output of 26 power plants. To avoid the drain of these "energy vampires", plug them into a power strip and turn it off when they are not in use.

31. Turn off your charges

Most cell-phone chargers continue to draw electricity even when the phone isn't plugged into it. If your cell-phone charger averages five watts per hour and is plugged in all the time, that means a total of more than 40 kilowatt-hours every year, or about 93 pounds of CO2. The same problem applies to your other electronic equipment, your laptop, iPod, digital camera, and BlackBerry. Unplug all your chargers when they are not in use.

32. Recycle your batteries

Although the number of electrical gadgets that use disposable batteries is on the decline, each person in the US discards eight batteries per year. Overall, Americans purchase nearly three billion batteries annually, and about 179,000 tons of those end up in the garbage. Batteries have a high concentration of metals, which if not disposed of properly can seep into the ground when the casing erodes. Avoid disposable batteries by using your outlets whenever possible. If you can't do without batteries, use rechargeable and recycled ones. You should also have your batteries collected and recycled. Go to www.rebat.com for a list of companies that participate in battery reclamation.

33. Turn off your computer when you leave at night

While computers do require a power surge when you first turn them on, they don't need enormous amounts of electricity to function for lengthy periods. Also, you can set your computer on "sleep" mode, which uses about three watts per hour, if you are going to be away from your desk for more than 15 minutes.

34. Get involved

Recycling at home doesn't get you off the hook at work. If your office doesn't recycle, or recycles only paper, find out why. If you work in a small office, call your local authority to discover what recycling equipment and services are available. These may include storage containers and compacters as well as collection. If you work in a larger office, ask your building-services coordinator why there are no recycling facilities and whom you would need to speak to about starting a recycling program for paper, glass, metal, and plastic. For more information, visit earth911.org.

35. Print double-sided

American businesses throw away 21 million tons of paper every year, 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). This has the added advantage of halving the paper pile on your desk. To further cut your paper wastage, make sure you always use "print preview" mode to check that there are no overhanging lines and that you print only the pages you need. Other ways to cut down on paper before you get to the printing stage include using single or 1.5 spacing instead of double spacing, and reducing your page margins.

36. Conserve water in your garden

Attach a barrel to your downspout that will collect rain from your roof's eaves. Your plants will thank you: rainwater is better for your garden, as the chlorine in tap water can inhibit plant growth. You can also save six gallons every minute of watering simply by attaching a trigger nozzle to your hose so that you use water only when it's needed. In addition, if you grow your grass a little longer, it will stay greener and require less water than a closely mowed lawn.

37. Create a living fence

When replacing yard fences, instead of building a wooden fence, opt for a living fence. A living fence is a hedge or row of trees, which can be groomed to maintain appearance. Not only is a living fence less expensive than a traditional fence, it also never needs to be painted. This saves you money and time and keeps harmful chemicals out of the environment. Try to use native flora and to avoid hedges comprised of only one species.

38. Recycle your newspaper

There are 63 million newspapers printed each day in the US; 44 million, or about 69 percent, of these will be thrown away. Recycling just the Sunday papers would save more than half a million trees every week.

39. Plant a tree

It's the simplest thing in the world to gather acorns, chestnuts, sweet chestnuts, and sycamore seeds in the autumn, plant them immediately, and forget them until the following spring. The success rate for acorns is not as high as for the other three, but in a good year about 40 percent germinate into oak trees. There's little that will stop the others from growing into healthy trees within the first year. Start saplings in styrofoam coffee cups, which can be split with a knife so that the roots aren't disturbed when you plant them outdoors. Keep the saplings for four or five years, then plant them in your own garden, offer them to friends, or return them to nature. It may seem like a very small contribution, but if 5 percent of the US population were to germinate one tree in one year, there would be almost 15 million extra trees absorbing carbon from the atmosphere.

40. Avoid pesticides

Use natural methods of pest control. Form a log pile, dead wood provides a habitat for many kinds of wildlife, such as snakes and ground beetles. Both are natural predators for snails and slugs. If you create a small pond to encourage frogs and toads, they will help mop up the rest of your slug life. In the short term you can get rid of slugs using beer traps (slugs are attracted to yeast). To get rid of whiteflies, buy Encarsia formosa, small parasitic wasps that eat whiteflies. Grow flowers such as marigolds to attract ladybugs, hoverflies, and lacewings, all of which protect against aphids.

41. Bat boxes

Want to reduce the number of mosquitoes in your backyard? Then invest in a bat box. One bat can eat up to 1,000 mosquitoes a night. You will also be making a contribution to our country's temperate biodiversity: bat populations in America and around the world are declining, especially in urban areas, where they have few roosting spaces. Ideally, group two or three boxes together, place them as high as possible, and face them so the sun directly heats them for six to seven hours each day. If you are making a bat box yourself, use untreated and unpainted wood. It is essential that bats not be disturbed, so make certain your bat boxes cannot be reached by any local cats. For more information, visit www.batconservation.org.

42. Walk or bike

Always consider alternatives to driving, especially for journeys under two miles. It's better for the environment to walk, cycle, or even take the bus than to hop in your car. Currently, only 2 percent of employed adults walk to work in the US. Walking adds to life expectancy, is safe, helps with mental and physical health, and, best of all, is completely free. Cycling is another way to get around and has recently become more popular, what with more bike paths and cool new gadgets like LED lights for riding in the dark. New kinds of folding bikes have been specially developed for the commuter. Surprisingly, recent studies have shown that bicyclists in cities are less exposed to air pollution than people in cars and taxis.

43. Buy a hybrid

Hybrid cars, which run on a combination of a gasoline engine and an electric motor, are all the rage these days. They get up to 50 miles per gallon, while a typical SUV might travel around 15 m.p.g. Hybrids can offer substantial savings, and you may qualify for a one-time tax credit of up to $3,400. For information on US hybrid-car incentives, go to www.hybridcars.com.

44. Biofuels 101, part 1

Have you heard of biofuels? Biodiesel and bioethanol are alternative fuels derived from crops such as sugarcane, oilseed rape, and used cooking oil, which are generally blended with diesel fuel or gasoline. Biofuels are available in a range of different blends, for example, 30 percent biofuel and 70 percent gas or diesel. Biodiesel is generally appropriate for any diesel vehicle designed to run on low-sulphur diesel. Biodiesel blends are becoming more widely available in the US. Check www.biodiesel.org to find out about local availability.

45. Biofuels 101, part 2

Bioethanol is an alcohol-based fuel. A 5 percent blend of bioethanol can be included in ordinary gas and used by any car in the US that runs on unleaded gas. You may already be using bioethanol-blended gas, as the 5 percent version is now being sold in the US through unmarked unleaded-gas pumps. Saab and Ford both have a flex-fuel model available, which can run on bioethanol-based fuel or on straight gasoline. If you drive an older model, you can still use biofuel if you are willing to have your car converted to flex-fuel.

46. Discover your carbon footprint

If you think you're already pretty green, determine your carbon footprint: a measurement of how your lifestyle choices affect carbon emissions. Your footprint will take into account your habits, the food you eat, your gas and electricity usage, your car and air mileage. Your score will be compared to the average figures for your county. These online tests aim to help you estimate your own carbon emissions and calculate how much of the planet's resources are required to sustain your lifestyle. They may motivate you to make changes, helping you set simple goals to reduce your negative impact on the planet. To learn about your carbon footprint, go to www.carbonfootprint.com/calculator.html.

47. Get an electric lawn mower

Surrender your gas lawn mower. Gasoline lawn mowers are among the dirtiest of modern machines. A study funded by the Swedish EPA found that using a four-horsepower lawn mower for an hour causes the same amount of pollution as driving a car 93 miles. The trouble with gas lawn mowers is that they not only emit a disproportionate amount of CO2, they are also responsible for releasing carcinogens such as polycyclic aromatic hydrocarbons into the air. Retire the noisy monster and buy an electric or manual model. Better still, reduce the number of times you mow per season and let some of your lawn grow wild, which has added benefits for bugs, butterflies, and birds. For more information, visit www.greengrasscutters.com.

48. Green grilling

If you have a charcoal barbecue grill, make sure your charcoal comes from a sustainable source. Enormous areas of tropical rainforest are destroyed every year to produce the 900,000 tons of charcoal burned annually in the US. Chimney starters are the most environmentally friendly solution to lighting charcoal. They use only a couple of pieces of newspaper, meaning you can avoid the gas-flavored meat that accompanies barbecues started with lighter fluid or fire starters. If you are replacing your grill, remember that using a gas, rather than charcoal, grill is the most environmentally friendly way to barbecue. It avoids forest destruction and doesn't add to local air pollution.

49. Re-gift gift wrap

Help cut down on the consumption of paper and plastic by re-using wrapping paper, ribbons, bows, and gift bags. These items should be good for at least one more wrapping. If you are feeling creative, use old calendars, pages from magazines, or even newspaper to wrap gifts.

50. A green ending

Green funerals don't just mean a woodland burial. Very few people actually know about the green alternatives to steel or hardwood coffins. Many private funeral homes present green alternatives to traditional coffins, including wicker caskets and shrouds. Currently, 89 percent of coffins sold are made of chipboard that is manufactured using formaldehyde. When chipboard coffins are cremated, they can release toxic gases. If buried, they disrupt local ecosystems; as the chipboard decays, the formaldehyde and glue leach into the soil and groundwater. Finally, most people opting for a green good-bye will choose a meadow or woodland burial, with only a memorial tree marking the grave.
