The Five Most Important Things You Can Do for the Environment

If you feel you’re not doing enough for the environment by replacing your incandescent light bulbs with CFL or LED lights and composting your kitchen garbage, maybe you’re ready to make a deeper commitment to environmental stewardship.
Some of these strategies may seem a little radical, but they are among the most valuable actions you can take to protect and preserve Earth’s environment.
Have Fewer Children—or NoneOverpopulation is arguably the world’s most serious environmental problem, because it exacerbates all of the others. The global population grew from 3 billion in 1959 to 6 billion in 1999, an increase of 100 percent in just 40 years. According to current projections, the world population will expand to 9 billion by 2040, a slower growth rate than during the last half of the 20th century but one that will leave us with many more people to accommodate.
Planet Earth is a closed system with limited resources—only so much fresh water and clean air, only so many acres of land for growing food. As the world population grows, our resources must stretch to serve more and more people. At some point, that will no longer be possible. Some scientists believe we have already passed that point.
Ultimately, we need to reverse this growth trend by gradually bringing the human population of our planet back down to a more manageable size. This means more people must decide to have fewer children. This may sound pretty simple on the surface, but the drive to reproduce is fundamental in all species and the decision to limit or forgo the experience is an emotional, cultural or religious one for many people.
In many developing countries, large families can be a matter of survival. Parents often have as many children as possible to ensure that some will live to help with farming or other work, and to care for the parents when they are old. For people in cultures like these, lower birth rates will only come after other serious issues such as poverty, hunger, poor sanitation and freedom from disease have been adequately addressed.
In addition to keeping your own family small, consider supporting programs that fight hunger and poverty, improve sanitation and hygiene, or promote family planning and reproductive health in developing nations.
Use Less Water—and Keep It CleanFresh, clean water is essential to life—no one can live long without it—yet it is one of the scarcest and most endangered resources on our increasingly fragile planet.
Water covers more than 70 percent of the Earth’s surface, but most of that is salt water. Freshwater supplies are much more limited, and today a third of the world’s people lack access to clean drinking water. According to the United Nations, 95 percent of the cities worldwide still dump raw sewage into their water supplies. Not surprisingly, 80 percent of all illnesses in developing countries can be linked to unsanitary water.
Use only as much water as you need, don’t waste the water you do use, and avoid doing anything to taint or endanger water supplies.
Eat ResponsiblyEating locally grown food supports local farmers and merchants in your own community as well as reducing the amount of fuel, air pollution and greenhouse gas emissions required to move the food you eat from the farm to your table. Eating organic meat and produce keeps pesticides and chemical fertilizers off your plate and out of rivers and streams.
Eating responsibly also means eating less meat, and fewer animal products such as eggs and dairy products, or perhaps none at all. It’s a matter of good stewardship of our finite resources. Farm animals emit methane, a potent greenhouse gas that contributes to global warming, and raising animals for food requires many times more land and water than growing food crops.
Livestock now use 30 percent of the planet’s land surface, including 33 percent of farmland worldwide, which is used to produce animal feed. Every time you sit down to a plant-based meal instead of an animal-based meal, you save about 280 gallons of water and protect anywhere from 12 to 50 square feet of land from deforestation, overgrazing, and pesticide and fertilizer pollution.
Conserve Energy—and Switch to Renewable EnergyWalk, bike and use public transportation more. Drive less. Not only will you be healthier and help to preserve precious energy resources, you’ll also save money. According to a study by the American Public Transportation Association, families that use public transportation can reduce their household expenses by $6,200 annually, more than the average U.S. household spends on food every year.
There are dozens of other ways you can conserve energy—from turning off lights and unplugging appliances when they are not in use, to substituting cold water for hot whenever practical and weather stripping your doors and windows, to not overheating or overcooling your home and office. One way to start is to get a free energy audit from your local utility.
Whenever possible, choose renewable energy over fossil fuels. For example, many municipal utilities now offer green energy alternatives so that you can get some or all of your electricity from wind, solar or other renewable energy sources.
Reduce Your Carbon FootprintMany human activities—from using coal-fired power plants to generate electricity to driving gasoline-powered vehicles—cause greenhouse gas emissions that contribute to climate change.
Scientists are already seeing significant climate changes that point to the likelihood of serious consequences, from increasing drought that could further reduce food and water supplies to rising sea levels that will submerge islands and coastal regions and create millions of environmental refugees.
Online calculators can help you measure and reduce your personal carbon footprint, but climate change is a global problem that requires global solutions and, so far, the world’s nations have been slow to find common ground on this issue. In addition to lowering your own carbon footprint, let your government officials know that you expect them to take action on this issue—and keep the pressure on until they do.

Op-Ed: Fighting new flu strain will take collective vigilance

Every fall, we deal with new strains of seasonal flu. But this year, we'll also confront a potentially serious flu virus that first appeared last spring. While scientists won’t know exactly how strong the 2009 H1N1 flu will be until the middle of the flu season, they’re warning it could cause more illness as our kids return to school.We don’t need to wait to act. In the fight against flu, preparation is more than half the battle — and we need everyone to chip in.We in the federal government have been aggressively responding to the new H1N1 since April. We’re building on what we learned from the early spring season and from health officials in the southern hemisphere where flu seasons are already underway. In addition to preparing the seasonal flu vaccine as usual, government scientists and vaccine manufacturers are working around the clock to produce a vaccine to protect people from the new H1N1 flu virus. And we’re making good progress on both fronts — the seasonal flu vaccine is ready for distribution and we’re on track to have an H1N1 vaccine by mid-October. We’re also working closely with cities, states and across government agencies to make sure we have a rapid, coordinated response this fall. In the last few months, we’ve sent more than $350 million in federal grants to states, tribes, territories and hospitals to help them strengthen their flu response. In early July, the Departments of Health and Human Services, Homeland Security, and Education held a flu summit for governors and public health officials. Just this week, we hosted another summit for mayors and county officials and webcast it on flu.gov — which has become the best place to find up-to-date information about flu. Our agencies are working with the Department of Agriculture to make sure children will have access to healthy meals if their schools close, and with Departments of Commerce and Labor to reach people at work. The Obama Administration has briefed members of Congress at a special bi-cameral, bi-partisan session. And HHS has worked with Members — Republicans and Democrats — on “prevent the flu” public service announcements to air in August when they’re home. But federal government efforts won’t be enough. The lines of defense against the flu need to reach into every living room and kitchen.This new H1N1 is not the flu we’re used to. It was just getting started when our flu season should have been ending. While anyone can get sick, the pattern of infection is unusual. It hasn’t yet affected many seniors, but it spreads rapidly among otherwise healthy kids up to college age. Scientists at the Centers for Disease Control and Prevention continue to observe higher levels of flu-like illness than normal for this time of year. But there’s one way in which the 2009 H1N1 flu isn’t different: it can still send you to the hospital with fever, cough, sore throat, headache, chills and fatigue, and sometimes, diarrhea and vomiting. For the worst cases, it’s still deadly. And it’s especially dangerous for people with chronic illnesses such as asthma, heart disease, or diabetes, and women who are pregnant. Until a vaccine arrives in October, prevention is our best defense. That means we all need to make sure we wash our hands frequently with soap and water, cough or sneeze into a tissue, and stay home from work or school if we’re sick. It also means planning ahead. Parents should talk to their employers and make child care arrangements in case their kids get sick. And if a school closes, learning shouldn’t stop. Schools need to create opportunities to learn online and work with parents to find ways for students to bring textbooks and other resources home. If you’re an employer, you should plan to get by with a reduced staff. You don’t want an employee who’s ill to spread flu in the workplace. If you’re a medical provider, you should plan to handle more calls and patient visits. An outbreak will bring people who have flu and people who have flu-related symptoms or concerns into your office. To help people get ready for flu season, we’ve created a “one-stop” website — www.flu.gov. You’ll find tips to prevent, and respond to an outbreak and checklists and fact sheets that will help families, businesses and others get prepared. We got a head start on the flu season by beginning our preparations this spring. But the next few months will have the biggest impact on how the upcoming flu season plays out. Widespread, determined, and sustained efforts are needed to prevent the spread of flu and reduce the harm it causes. Let’s get to work.

2nd lead poisoning case hits China, 1,300 sick

China detained two factory officials after 1,300 children were poisoned by pollution from a manganese processing plant, state media said Thursday, days after emissions from a lead smelter in another province sickened hundreds.
Both cases have sparked unrest and come amid growing anger in China over public safety scandals in which children have been the main victims. Tainted infant formula milk and the mass collapse of schools in a huge earthquake last year have also provoked widespread dissent.
The latest incident involves the Wugang Manganese Smelting Plant in Wenping township, central Hunan province. It opened in May 2008 without the approval of the local environmental protection bureau, within 500 yards (meters) of a primary school, a middle school and a kindergarten.
Fears of poisoning began to spread among villagers in early July when many children became susceptible to colds and suffered fevers and other ailments, the official Xinhua News Agency said.
Some 1,354 children who live near the plant — or nearly 70 percent of those tested — were found to have excessive lead in their blood, Xinhua said. Lead poisoning can damage the nervous and reproductive systems and cause high blood pressure and memory loss.
Local authorities shut down the smelter last week and detained two of its executives on suspicion of "causing severe environmental pollution," Xinhua said. General manager Liu Zhongwu was still at large, it said.
Li Liangmei, a 36-year-old mother of two affected children, said hundreds of villagers rioted Aug. 8 after news broke about the lead poisoning. She said a crowd of about 600 to 700 people overturned four police cars and smashed a local government sign.
"People were angry about the test results," Li said. Her 13-year-old daughter and 8-year-old son were among the hundreds found to have lead in their blood above safe levels.
Earlier this week, villagers in Shaanxi, another rural province in central China, clashed with police as they protested the operations of the Dongling Lead and Zinc Smelting Co. in the town of Changqing. They also stoned trucks trying to deliver coal to the plant.
That unrest came after at least 615 out of 731 children in two villages near that smelter tested positive for lead poisoning. Children from six other villages there are now being tested.
Children's health can be a particularly volatile issue in China, where most families are restricted to having just one child.
A string of recent safety scandals has put parents on high alert, including a national problem with tainted infant formula that killed at least six babies, and the mass collapse of schools in last year's Sichuan earthquake that left thousands of students dead. Critics blamed poor government oversight for the milk, and local corruption and profit-skimming for the allegedly shoddy school buildings.
Seeking to restore public trust, the Communist Party leadership has vowed in each case to deal harshly with those responsible for endangering children. But heavy-handed efforts to silence angry parents, including threats and house arrest, have further damaged the party's image and undermined its pledge to "put people first."
Zhao Lianhai, the father of a child who was sickened by tainted milk, blamed local government greed for the new lead poisoning cases and expressed sympathy for the families affected.
"It is said that children are the flower of the motherland and I am sad to see these flowers devastated," he said in a telephone interview. "The government should value the children more than this, care for them and do more to protect their food and living conditions."
Since his son became ill, Zhao has turned to activism, seeking punishment for those implicated in the milk scandal and free medical care for victims. Some 294,000 infants suffered urinary problems from drinking the infant formula contaminated with the industrial chemical melamine.
On the case of the manganese smelter in Hunan, a Wenping township government official who declined to give his name said the numbers of children with lead poisoning are expected to rise as more children are tested.
Xinhua said preliminary tests found that children from four villages near the plant were affected but that many are being tested again in the provincial capital, Changsha, to see how serious their cases are.
Li, the mother of two affected children, said villagers are also angry over discrepancies in test results, with levels reported in their home county allegedly lower than those conducted in Changsha.
"People suspect that the factory owner and the government bribed the hospital to forge the results," she said

Australian Parliament sets renewable energy target

Australia's Parliament passed a law Thursday to require that 20 percent of the country's electricity come from renewable sources such as the sun and wind by 2020, matching European standards and up from about 8 percent now.
The law would quadruple the renewable energy target set by the previous government in 2001 and provide enough clean electricity to power the households of all 21 million Australians.
The target matches one set in 2007 by the European Union, which leads the world in green power technology.
But some officials warn that more aggressive cuts in carbon gas emissions are needed as well.
The bill was passed by the Senate and House of representatives on Thursday after the government reached a deal with the main opposition party to increase government assistance to industries that are heavy users of electricity and create safeguards for existing investment in the coal mining industry.
Sen. Bob Brown, leader of the Australian Greens minor opposition party, said the target should be 30 percent and that big polluters were offered too much government assistance.
Sen. Bob Fielding, an independent, said the bill will make power too expensive.
"It's moms and dads that will be subsidizing wind-powered electricity, solar — these are very expensive," he said.
Currently, 8 percent of Australia's electricity comes from renewable sources, including hydroelectric generators built late last century, according to the private Clean Energy Council.
Critics argue the target will make electricity more expensive in coal-rich Australia without curbing the amount of climate-warming carbon gases that the nation emits, as overall electricity consumption rises.
Climate Change Minister Penny Wong told the Senate on Wednesday that even with one-fifth of Australia's electricity coming from renewable sources by 2020, the nation's carbon gas emissions are projected to be 20 percent higher than 2000 levels.
"The only way we're going to be able to turn around the growth in our carbon pollution ... is to put a firm legislated limit on the amount of carbon that we produce and make those who create the pollution pay for it," Wong said.
Last week the Senate rejected a government-proposed bill that would have taxed industries' carbon emissions starting in 2011 and slashed the country's emissions by up to 25 percent below 2000 levels by 2020

Air Pollution May Reduce Rainfall and Cause Drought

As if there weren't already plenty of reasons to cut back on air pollution, now it looks as though cleaner air may reduce drought.
New research by the U.S. Department of Energy’s Pacific Northwest National Laboratory makes a strong case that air pollution is contributing to drought conditions and potential crop failure in northern China by reducing the type of light rainfall that is essential for agriculture.
According to the study, published in the Journal of Geophysical Research, air pollution reduced the number of days of light rainfall in China by 23 percent between 1956 and 2005. Light rainfall is defined as anything up to 0.4 inches (10 millimeters) in a day.
The way this works is that air pollution causes tiny air particles called aerosols—some aerosols also occur naturally—which affect how rain clouds form. Although the number of water droplets in clouds is higher when more aerosols are present, the water droplets in polluted skies are up to 50 percent smaller than in clean air. Many are so small that they are unable to fall as rain.
The research study shows that most of the aerosols in China are caused by human activity, such as the use of fossil fuels. China’s population and fossil fuel consumption increased dramatically between 1960 and 2000, and so did the number of aerosols in China’s skies. The result was the significant decrease in light rainfall noted in the study, and more drought in northern China. Heavy rainfall, which actually increased in some parts of southern China during the same period, can cause flooding and wash away crops before they have a chance to ripen and be harvested.
The conclusion of the researchers is that reducing air pollution in China could help to relieve drought, as well as decreasing acid rain and health problems associated with air pollution. About 2.5 million hectares of crops in northern China and Inner Mongolia are currently threatened by drought, raising concerns that the autumn grain harvest (which accounts for more than 70 percent of China’s total grain crop) could be ruined.

Do the Benefits of Recycling Outweigh the Costs?

Controversy over the benefits of recycling bubbled up in 1996 when columnist John Tierney posited in a New York Times Magazine article that “recycling is garbage.”
“Mandatory recycling programs,” he wrote, “…offer mainly short-term benefits to a few groups -- politicians, public relations consultants, environmental organizations and waste handling corporations -- while diverting money from genuine social and environmental problems. Recycling may be the most wasteful activity in modern America…”
Cost of Recycling vs. Trash CollectionEnvironmental groups were quick to dispute Tierney on the benefits of recycling, especially on assertions that recycling was doubling energy consumption and pollution while costing taxpayers more money than disposing of plain old garbage.
The Natural Resources Defense Council and Environmental Defense, two of the nation’s most influential environmental organizations, each issued reports detailing the benefits of recycling and showing how municipal recycling programs reduce pollution and the use of virgin resources while decreasing the sheer amount of garbage and the need for landfill space -- all for less, not more, than the cost of regular garbage pick-up and disposal.
Michael Shapiro, director of the U.S. Environmental Protection Agency’s Office of Solid Waste, also weighed in on the benefits of recycling:
“A well-run curbside recycling program can cost anywhere from $50 to more than $150 per ton…trash collection and disposal programs, on the other hand, cost anywhere from $70 to more than $200 per ton. This demonstrates that, while there’s still room for improvements, recycling can be cost-effective.”
But in 2002, New York City, an early municipal recycling pioneer, found that its much-lauded recycling program was losing money, so it eliminated glass and plastic recycling. According to Mayor Michael Bloomberg, the benefits of recycling plastic and glass were outweighed by the price -- recycling cost twice as much as disposal. Meanwhile, low demand for the materials meant that much of it was ending up in landfills anyway, despite best intentions.
Other major cities watched closely to see how New York was faring with its scaled back program (the city never discontinued paper recycling), ready to perhaps jump on the bandwagon.
But in the meantime, New York City closed its last landfill, and private out-of-state landfills raised prices due to the increased workload of hauling away and disposing of New York’s trash.
As a result, the benefits of recycling glass and plastic increased and glass and plastic recycling became economically viable for the city again. New York reinstated the recycling program accordingly, with a more efficient system and with more reputable service providers than it had used previously.
Benefits of Recycling Increase as Cities Gain ExperienceAccording to Chicago Reader columnist Cecil Adams, the lessons learned by New York are applicable everywhere.
“Some early curbside recycling programs…waste resources due to bureaucratic overhead and duplicate trash pickups (for garbage and then again for recyclables). But the situation has improved as cities have gained experience.”
Adams also says that, if managed correctly, recycling programs should cost cities (and taxpayers) less than garbage disposal for any given equivalent amount of material.
Even though the benefits of recycling over disposal are manifold, individuals should keep in mind that it better serves the environment to “reduce and reuse” before recycling even becomes an option.
