Top Three
- Consider having a small family or not reproducing at all.
- Every 20 minutes, the
world adds another 3,500 human lives but loses one or more entire species of animal or plant life—at least 27,000 species per year.
- An average American's
environmental impact is 30 to 50 times that of the average citizen of a developing country such
as India.
- The richest fifth of the
world's population consumes 86 percent of all goods and services and produces 53 percent of all
carbon dioxide emissions, while the poorest fifth consumes 1.3 percent of goods and services and
accounts for three percent of carbon dioxide output.
- The world's forests have
shrunk from 11.4 to 7.3 square kilometers per 1,000 people since 1970. The loss is concentrated
in developing countries, mostly to meet the demand for wood and paper by the industrialized
world. Population
Connection: Population and the Environment
- Consider reducing or even eliminating meat from your diet.
- Meat is extremely
inefficient to produce compared to non-meat alternatives. In fact, the Union of Concerned
Scientists says that not eating beef is one of the most important things people can do to help
the environment, second only to driving a fuel-efficient automobile (not an SUV or a truck) and
living close to work.
- Ten people could be fed
with the grain required to feed a cow that would be turned into food for one person.
- You'd save more water by
giving up one pound of beef per year than you would by not showering for six months. Earth Save: How Our Food
Choices Can Help Save the Environment
- Drive a smaller car and drive less.
General
- Get out and enjoy your local natural wonders. Hike. Spend some time in a park. To
know your local resources is to love them; to love them is to want to protect them. NRDC: The Green Gate
Consume Less
- Stop unwanted mail. Every 1,000 people who succeed in halving their personal bulk
mail will save 170 trees, nearly 46,000 pounds of carbon dioxide, and 70,000 gallons of water
each year. Turn the Tide:
Nine Actions for the Environment
- Buy recycled products. Look on the label for the products or packaging with the
greatest percentage of post-consumer recycled content, which ensures that the materials have been
used before. NRDC: Guide to Greener
Living
- Buy products with less packaging. A large percentage of the paper, cardboard, and
plastic we use goes into packaging, much of it wasteful and unnecessary. NRDC: Guide to Greener Living
- Leave grass clippings on the lawn. Grass clippings make good fertilizer when they
decompose, and leaving them on your lawn keeps them from occupying limited space in the local
landfill. NRDC: Guide to Greener
Living
- Re-use products before recycling them—paper and plastic bags at the grocery
store, for example. Better yet, carry a cloth bag. NRDC: The Green Gate
Conserve Water
- Install an ultra-low-flush toilet or a toilet displacement device. About 40 percent
of the water you use in your home gets flushed down the toilet, at a rate of more than 4 billion
gallons of water in the US each day. NRDC: Guide to Greener Living
- Inexpensive and simple to install, low-flow shower heads and faucet aerators can
reduce your home water consumption and reduce the cost of heating the water by as much as 50
percent. Earth Easy:
Low-Flow Aerators
- Install a low-flow showerhead. Showers account for 32 percent of home water use. A
family of four using low-flow showerheads can save about 20,000 gallons of water per year. NRDC: Guide to Greener Living
- If you're landscaping, use plants that are native to your area. Growing native
plants can save more than half the water normally used to care for outdoor plants. NRDC: Guide to Greener Living
- Avoid over-watering lawns and gardens—which can increase the leaching of
fertilizers into groundwater—by using slow-watering techniques. Trickle or 'drip' irrigation
systems and soaker hoses are 20 percent more efficient than sprinklers. NRDC: How to Clean Up Our Water
- To improve drainage around your home and in your yard, decrease impervious surfaces
such as concrete and asphalt. As alternatives, do your landscaping with vegetation, gravel or other
porous materials; install wood decking; and use interlocking bricks and paver stones for
walkways. NRDC: How to Clean Up
Our Water
- Check your pipes and faucets for leaks or drips. Even a small drip can waste
thousands of gallons of water each year. NRDC: The Green Gate
- Don't put hazardous materials, pesticides, oil, prescription drugs, or personal
care products down the drain or toilet—they'll wind up in local waterways.
NRDC: The Green Gate
- Have your water supplier do a residential audit of your home—many will come for
free, and make specific recommendations to improve the water efficiency of your home. NRDC: The Green Gate
- Save water by redirecting runoff from your roof to strategic spots of your lawn or
garden. NRDC: The Green
Gate
- Avoid products from fisheries with excessive levels of 'bycatch', including shrimp
(wild and farm raised), scallops (wild), and oysters (wild). Bycatch of non-target species claims
as much as 29 million tons of fish, seabirds, turtles, and marine mammals every year. World Wildlife Fund: Conserving Oceans
Conserve Energy
- Use shading techniques—including landscaping, and working the drapes and blinds—as the simplest, the most effective way to reduce home energy consumption and save cooling costs by
up to 40 percent. Earth Easy:
Natural Cooling
- Close your curtains and shades at night to retain heat, and open them during the
day so that you can benefit from free solar heat. World Wildlife Fund: Make Your Home More Efficient
- To keep your house cool on hot days, finish its exterior in a light color paint and use a
high-reflectance roof covering. Sierra Club: Building a Greener House
- Install a door sweep—available at most hardware stores for $5 to $10—to
prevent the loss of inside heated air into the cooler air outside. Earth Easy: Cheaper Heat
- Install ceiling fans in major rooms. This will help cut both cooling costs in
summer and heating costs in winter. Sierra Club: Building a Greener House
- Install tight-fitting glass doors in front of your fireplace to both reduce
the likelihood that toxic gasses will leak into your house and reduce the amount of heated house
air that the fireplace exhausts up the chimney. Sierra Club: The Guilt-Reduced Fireplace
- To reduce heat loss from the chimney when your fireplace is not in use, keep the
damper closed. Having an open chimney in your house is about as energy efficient as drilling a
large hole in your refrigerator to make it easier to grab a soda. Sierra Club: The Guilt-Reduced Fireplace
- Don't burn newspaper, garbage, trash, cardboard, plastic, plywood, driftwood or
wood that is treated, painted or pressure-treated in a fireplace. All of these may contain toxic
chemicals that will be released into the atmosphere. Sierra Club: The Guilt-Reduced Fireplace
- Connect your PC, monitor, fax machine, and computer peripherals to a single power
strip that can be turned off when the equipment is not in use. This will end 'leakage' from
devices that drain power even when they aren't turned on. Sierra Club: Guide to Greener
Living
- Wrap your water heater in an insulating jacket to reduce carbon dioxide
emissions by up to 1,000 pounds per year. World Wildlife Fund: Stop Global Warming
- Insulate home walls and ceilings to save about 25 percent of home heating bills and
reduce carbon dioxide emissions by up to 2,000 pounds per year. World Wildlife Fund: Stop Global Warming
- Control heating with a digital thermostat that can be set for each zone of the home.
This can save 10 percent to 15 percent on heating and cooling costs. Sierra Club: Building a Greener House
- Save as much as 10 percent a year on your heating bills by simply turning your
thermostat back 10 to 15 percent for eight hours. You can do this automatically without
sacrificing comfort by installing a programmable thermostat. World Wildlife Fund: Make Your Home More Efficient
- During the winter, turn thermostats down to 68 degrees or below during the day and
55 degrees at night and when you're away from home. In warm weather, set thermostats to 78
degrees or above. NRDC: The Green
Gate
- If you have an air conditioner, change the filter once a year. An air conditioning
unit with dirty filters can use 5 to 10 percent more energy. Sierra Club: Energy Conservation
- Use compact fluorescent lightbulbs. Although are initially a lot more expensive
than the incandescent bulbs you're used to using, they last ten times as long and can save $30
per year in electricity costs. NRDC: The Green Gate
- If your refrigerator is more than nine years old, consider replacing it with a new
Energy Star model. New models use about 50 percent less energy than older refrigerators do. NRDC: The Green Gate
- Keep dryers in a warm area, where they'll work more efficiently. NRDC: The Green Gate
- Clean the lint filter of your dryer—doing so will not only make your dryer run
safely, it will reduce the amount of energy needed to dry your clothes. NRDC: The Green Gate
Reduce Toxins
- To deter an ant invasion, use crushed mint leaves, cloves, cinnamon, cayanne pepper,
lemon juice, coffee grounds, or garlic cloves instead of harmful chemicals. Earth Easy: Non-Toxic Home Cleaning
- For a natural moth deterrent, use cedar chips or oil; lavender, rosemary, or rose
petals; or dried lemon peels. The common mothball is made of paradichlorobenzene, which is
harmful to liver and kidneys. Earth Easy: Non-Toxic Home Cleaning
- If you really want outdoor windows to shine without using harmful chemicals, follow
cleaning with a rinse of water and white vinegar—about 1/2 cup of vinegar to a gallon of
water. This is a good all-around cleaning solution for other parts of your house, too, such as
floors and tubs. Sierra
Club: Washing Windows
- To clean your indoor windows without harmful chemicals, try club soda in a spray
bottle. The sodium citrate softens the water and increases the cleaning effectiveness. Sierra Club: Washing
Windows
- Don't apply pesticides unless you have an actual problem. Never use them to
'prevent' pests, since unnecessary prevention is a huge source of pollution. If you do have a
pest problem, try baits and traps instead of sprays—the more localized the poison is, the
better. NRDC: The
Green Gate
- If your pet has a flea problem, use pills from your veterinarian instead of flea
bombs, dips or collars. Consider regular bathing, flea combing, and vacuuming carpets. NRDC: The Green Gate
- Toilet bowl deodorizers, cleaning solutions with lye, and many spot removers
contain harmful chemical solvents. Use baking soda and diluted vinegar instead as all-purpose
cleaners. NRDC: The
Green Gate
- Use water-based paints instead of oil-based paints as they are less hazardous to
your health and to the environment. Also, never pour paint thinners and varnish down the sink or
toilet as they will end up in local waterways. NRDC: The Green Gate
- Consider trying 'wet cleaners' instead of dry cleaners that use harmful solvents.
If you do choose to dry-clean, air clothes outside before putting them in your closet. NRDC: The Green Gate
- Be careful with thermometers. Many contain mercury, and glass mercury thermometers
can break, contaminating the home. NRDC: The Green Gate
- Buy organic.
