Blog EntryNo tech cure for oceans 'damned' by plasticMar 31, '08 8:46 AM
for everyone
March 4, 2008 5:45 PM PST

Plastic contamination in the world's oceans is worse than previously imagined and no amount of technology can clean it up, according to Charles Moore. The oceanographer returned February 23 from a five-week odyssey in the Pacific Ocean with samples showing 48 parts plastic for every part of plankton.

"We are damned to a future of pollution by plastic," said Moore, who has spent more than a decade investigating Pacific plastic pollution. "There's no evidence it will end in a millennium."

Moore and his crew continue to study samples of plastic 'soup' from deep in the Pacific Ocean.

A plastic "graveyard" double the size of Texas swirls in the Pacific Ocean between San Francisco and Hawaii. There, his crew had found in the water six parts of plastic for every part plankton, with a fivefold increase in the amount of plastic between 1997 and 2007.

But their latest voyage found the pollution even thicker in the "highway" of ocean leading to the great Garbage Patch, according to Moore, who founded the Algalita Marine Research Foundation in Long Beach, Calif. Moore said that area comprises 2.5 million square miles.

In the Pacific alone, heavily polluted plastic zones amount to the size of the continent of Africa, Moore estimated.

Bobbing in the waters, especially closer to shore, are leftovers of everyday consumer products: plastic bags, toothbrushes, cigarette lighters, bottles and their caps, toys, and fast food wrappers.

"We found a video camera case that was clean enough that you could put a video camera in it, but it was starting to get covered in barnacles," he said.

Eighty percent of garbage within waterways, most of it plastic, begins its journey on land rather than coming from boats, according to Algalita and the California Coastal Commission.

Toxic plastic kills wildlife, poisons seafood, and could even exacerbate global warming.

Stories abound of the bellies of birds and sea creatures stuffed with colorful plastic caps and wrappers mistaken for food.

On their latest trip, Moore's crew was shocked to find that plastic could be creating new habitats. Hungry gulls are traveling far from home into the ocean to feast upon barnacles and crabs attached to plastic debris.

Although there's no solid data about how much plastic birds and fish are eating, plastic in seafood is likely harmful for people to eat, as are better-understood toxic metals such as mercury. Plastic acts like a sponge for poisons such as PCBs, concentrating them at levels a million times higher than in seawater.

Plastic ingredients are linked with various cancers and reproductive problems. For instance, bisphenol A, found in water bottles, has shown in lab rats to disrupt hormones and is associated with obesity and diabetes.

Some scientists believe that those bobbing bits of polymer in the ocean could contribute to global warming by creating a shaded canopy that makes it harder for plankton to grow.

Pelagic crabs attached to plastic, like this laundry basket pulled from the ocean, attract hungry birds.

The deeper Moore's crew traveled into the Garbage Patch, the harder it became to tell what the plastics used to be. That's because the material breaks down into dusty bits. The plastic "soup" is visible up close but not from the air, making its scale difficult to measure with satellite or aerial imagery, he said.

"Day after day, sitting on the bow of that ship, seeing confetti on the surface of ocean, you really become appalled," Moore said.

He gets e-mails nearly every day from companies proposing plastic cleanup methods for the oceans, but none seem feasible by a long shot, he said.

"They want to have navies trawling the ocean, but the ocean's average depth is 2 miles. First you've got to prove you can sift the Sahara Desert."

And Moore is cautious about plans from start-ups such as Climos, which is seeking to seed the ocean with plankton, because there's no proof the algae they'd grow would be safe.

Because Moore sees no way to eliminate the plastic pollution, he urges consumers to change their habits to keep plastic out of waterways. And he wants plastics that can't be recycled not to be produced in the first place.

He and other activists hope for the government to accelerate research into alternatives, perhaps even subsidizing the makers of bioplastics, while building a better recycling infrastructure.

Only about 3 percent of plastics are recycled, according to the Environmental Protection Agency. And of those that are recycled, most appear to be sent abroad because there are relatively few plastics recycling centers in the United States.

Moore is suspicious, however, of new, 'green' plastics that haven't been studied in-depth and whose labels don't show how long they would take to break down in water as opposed to a compost heap.

Promoting the green design, construction, renovation and operation of buildings could cut North American greenhouse gas emissions that are fuelling climate change more deeply, quickly and cheaply than any other available measure, according to a new report issued by the trinational Commission for Environmental Cooperation (CEC).

North America’s buildings cause the annual release of more than 2,200 megatons of CO2 into the atmosphere, about 35 percent of the continent’s total. The report says rapid market uptake of currently available and emerging advanced energy-saving technologies could result in over 1,700 fewer megatons of CO2 emissions in 2030, compared to projected emissions that year following a business-as-usual approach. A cut of that size would nearly equal the CO2 emitted by the entire US transportation sector in 2000.

It is common now for more advanced green buildings to routinely reduce energy usage by 30, 40, or even 50 percent over conventional buildings, with the most efficient buildings now performing more than 70 percent better than conventional properties, according to the report.

Despite proven environmental, economic and health benefits, however, green building today accounts for a only small fraction of new home and commercial building construction—just two percent of the new non-residential building market, less than half of one percent of the residential market in the United States and Canada, and less than that in Mexico.

The report, Green Building in North America: Opportunities and Challenges, is the result of a two-year study by the CEC Secretariat. It was prepared with advice from an international advisory group of prominent developers and architects, sustainability and energy experts, real estate appraisers and brokers, together with local and national government representatives.

“Improving our built environment is probably the single greatest opportunity to protect and enhance the natural environment. This report is a blueprint for dramatic environmental progress throughout North America—mostly using the tools and technology we have on hand today,” says CEC Executive Director Adrián Vázquez. “Green building represents some of the ripest ‘low-hanging fruit’ for achieving significant reductions in climate change emissions.”

Even with rapid growth projected in the green building market across all three countries, the report says public and private sectors must embrace substantial changes to the planning, development and financing of commercial and residential buildings to overcome what it says are significant barriers to the widespread adoption of high-performance buildings throughout North America.

Jonathan Westeinde, managing partner of The Windmill Development Group in Ottawa and the CEC’s advisory group chair, states “As a developer, I rely on the fact that green building is a proven concept—with construction costs and market benefits that are rapidly improving. This report shows what is needed to scale up and put green building at the heart of a healthy, energy-secure North America.”

The report highlights the importance of green building in urban development. Seattle Mayor Greg Nickels, whose city hosted a CEC symposium on green building in May 2007, states, “Green building is a cornerstone for creating strong, sustainable communities. In Seattle, we are convinced that cities that make the commitment and investment in green development now will have a significant advantage in the long run.”

Report authors describe a number of disincentives to green building to be overcome. For example, how to encourage developers to incur the marginal cost of green building features when the long-term energy-saving benefits will be passed on to the new owners or tenants.

They recommend ways to accelerate the market uptake of green building and make it the standard practice for all new construction and renovation of existing buildings in North America. Among its recommendations, the report calls upon North American government, industry and nongovernmental leaders to:

Create national, multi-stakeholder task forces charged with achieving a vision for green building in North America;

Support the creation of a North American set of principles and planning tools for green building;

Set clear targets to achieve the most rapid possible adoption of green building in North America, including aggressive targets for carbon-neutral or net zero-energy buildings, together with performance monitoring to track progress towards these targets;

Enhance ongoing or new support for green building, including efforts to promote private sector investment and proper valuation methods; and

Increase knowledge of green building through research and development, capacity building, and the use of labels and disclosures on green building performance. The recommendations complement ongoing efforts by federal, state/provincial and local governments as well as industry and trade associations and nongovernmental organizations.

The CEC study notes several government and industry initiatives that promote aggressive energy performance improvements in the building sector. One study completed for the report signals the potential of green building to yield tremendous energy improvements and greenhouse gas emissions reductions in the building sector by 2030, and suggests a path toward zero net-energy and carbon-neutral buildings.

Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, according to new research published in a special issue of Waste Management & Research (Special issue published today by SAGE).

Carbon sequestration in soil has been recognized by the Intergovernmental Panel on Climate Change and the European Commission as one of the possible measures through which greenhouse gas emissions can be mitigated.

One estimate of the potential value of this approach – which assumed that 20% of the surface of agricultural land in the EU could be used as a sink for carbon – suggested it could constitute about 8.6% of the total EU emission-reduction objective.

“An increase of just 0.15% in organic carbon in arable soils in a country like Italy would effectively imply the sequestration of the same amount of carbon within soil that is currently released into the atmosphere in a period of one year through the use of fossil fuels,” write Enzo Favoino and Dominic Hogg, authors of the paper.

“Furthermore, increasing organic matter in soils may cause other greenhouse gas-saving effects, such as improved workability of soils, better water retention, less production and use of mineral fertilizers and pesticides, and reduced release of nitrous oxide.”

However, capitalizing on this potential climate-change mitigation measure is not a simple task. The issue is complicated by the fact that industrial farming techniques mean agriculture is actually depleting carbon from soil, thus reducing its capacity to act as a carbon sink.

According to Hogg and Favoino, this loss of carbon sink capacity is not permanent. Composting can contribute in a positive way to the twin objectives of restoring soil quality and sequestering carbon in soils. Applications of organic matter (in the form of organic fertilizers) can lead either to a build-up of soil organic carbon over time, or a reduction in the rate at which organic matter is depleted from soils. In either case, the overall quantity of organic matter in soils will be higher than using no organic fertilizer.

“What organic fertilizers can do is reverse the decline in soil organic matter that has occurred in relatively recent decades by contributing to the build-up in the stable organic fraction in soils, and having the effect, in any given year, of ensuring that more carbon is held within the soil,” they explain.

But calculating the value of this technique to climate change policies is complicated. To refine previous calculations and to take account of the positive and negative dynamics of carbon storage in soil, Favoino and Hogg modelled the dynamics of compost application and build-up balancing this with mineralization and loss through tillage.

Their results suggest that soils where manure was added have soil organic carbon levels 1.34% higher than un-amended soils, and 1.13% higher than soils amended with chemical fertilizers, over a 50-year period. “This is clearly significant given the evaluations reported above regarding carbon being lost from soils, and the increasing amount of carbon dioxide in the atmosphere,” they say.

The Rich Stand Accused

If you want to be an ecologist, you have to stop being half-witted.” writes Hervé Kempf, author of the acclaimed Comment les riches détruisent la planète (How the Rich Destroy the Planet, Seuil, 2007). “We cannot understand the simultaneity of the ecological and social crises if we do not analyze them as two facets of the same disaster.”

A journalist who specializes in the environment for France’s respected newspaper Le Monde, Kempf has taken his work to the four corners of the planet and frequented – as is the privilege of an environmental chronicler – the cream of the scientific community. Yet, from these contacts and the issues patiently compiled for the newspaper where he works, he retains two observations:

First, he explains that the planet’s ecological situation is worsening at a rate that neutralizes all the efforts of millions of citizens and ecological militants, to the point that the planet is in danger of crossing a threshold of irreversibility “within the next 10 years,” he believes, on the basis of the speed at which negative outcomes are piling up.

The second observation of this attempt to provide a veritably comprehensive explanation of the environmental crisis is that “the social system that presently governs human society – capitalism – blindly, doggedly rejects the changes necessary if we want to preserve the dignity and promise of human existence.”

In the same way that the different aspects of the global environmental crisis react with more and more synergy – warming accelerates the rate of species extinction, as use of fossil fuel gives rise to pollution and consumption to the exhaustion of resources – the planetary ecological and social crises are two mutually bound-up facets of the same problem.

“This disaster derives from a system piloted by a dominant social stratum that today has no drive but greed, no ideal but conservatism, no dream but technology. This predatory oligarchy is the principal agent of the global crisis,” writes Kempf. “The present form of capitalism,” he adds in an interview, “has lost its former historic ends, that is to say the creation of wealth and innovation, because it has become a financial capitalism, disparaged even by capitalist economists. This capitalism, which destroys jobs by rationalizations, new technologies and globalizations, overall and everywhere increases the disparities between rich and poor within each country and between different countries.”

This oligarchy he targets is not satisfied with blindly consuming and wasting the planet’s material resources with its big cars, its airplane trips, its unbridled consumption of living products, its uselessly vast houses, its unrestrained energy wastage. It has also, adds Kempf, spawned a model of hyper-consumption that the lower and especially the middle classes now attempt to imitate, just as developing countries try to imitate western countries – even though, whether instinctively or rationally, everyone clearly knows that “this ideology of waste” and its drain on planetary resources will inevitably come to an abrupt end.

This course places before the human species the unprecedented fact that it has reached or soon will reach the planet’s limits, which could, through feedback effects, threaten the species’ own existence. But this course is all the more difficult to arrest, Hervé Kempf deems, because it depends on a semi-authoritarian regime ever more institutionalized at the planetary level. It even depends, he says, on crises like that of September 11 in order to appreciably reduce those human rights that had been acquired through elevated struggle and to neutralize, even cause to disappear, those democratic mechanisms that allow free public debate on the choice of plans, the social choices that the workings of the economy repeatedly raise.

Kempf rejects all accusations of attempting to take the planetary ecological debate from green to red.

“I am no Marxist,” he says, “and have never been, because that ideology does not respect human rights. But the Marxists do not have a monopoly over the social debate and we cannot, all the same, close our eyes to the documented, measured phenomena right in front of us. I note the existence of two crises, one ecological, the other social. And I observe that they act in synergy. I observe that a minority of people benefit from them. And I draw conclusions from these observations.”

But he also observes that a large part of the European left has not seen the depth of the links between the two problems, just as many ecologists – who restrict themselves to an environmental approach – miss half the problem, if not its first cause.

“We must,” he writes, “get past this hiatus. Understand that the ecological crisis and social crisis are two facets of the same disaster. And that this disaster is set in motion by a system of power that has no other end than the maintenance of the ruling classes’ privileges.”

Although he does not address the impact of unchecked demography on the decline of the planet’s “biological services” in his essay, Kempf immediately acknowledges that this factor certainly has an impact that is greater overall than any hyper-consumption by this oligarchy, composed of several hundred thousand millionaires and billionaires who control the bulk of income and financial capital. However, he explains, it’s this oligarchy that creates an unsustainable model for the planet, the indirect impact of which on other social groups exceeds its direct consumption. “And,” he says dryly, “not all humans have the same impact on the planet at birth: a Westerner carries more weight in the planet’s fate than a baby from Niger or from India.”

Kempf advocates to put an end to this ostentatious consumption. He proposes a radical control of wealth through “a ceiling on maximum salaries and on the accumulation of wealth,” a sort of matching piece for the minimum wage, but on the upper side.

“Everyone,” he comments, “knows that China will never be able to reach a level of consumption per inhabitant comparable to that of the Americans, with two cars per family, three televisions, four computers and cell phones, a house three times too big for its inhabitants, which generates energy consumption that would be sufficient to the needs of 10, even 20 people on other continents.” He proposes that a reduction of consumption be imposed on this oligarchy that has globalized poverty, so that it no longer feeds this unsustainable dream, which numbs the critical faculties of the entire planet to the point that it closes its eyes to the wall into which it is careening full speed ahead.

And the reporter, known for his rigor and level-headedness, nevertheless concludes: “It is still necessary for ecological concerns to be based on a radical political analysis of present relationships of domination. We will not be able to reduce global material consumption if the powerful are not brought down and if inequality is not combated. To the ecological principle so useful at the dawning of awareness – Think globally, act locally – we must add the principle that the present situation imposes: “Consume less, share better.”

Ecologists, he adds, have not often conducted an inquiry into the “ecological misery” that parks the poor next to industrial neighborhoods, polluted and at risk, next to highways or noisy activities, in the most insalubrious houses and in sectors generally the least well-served by public services, including public transportation. It is wrong, he says, to act as though the economic system must grow to bring these people out of poverty or to allow more poor people to attain greater wealth. The economic system works in the other direction, Kempf maintains, by monopolizing wealth and power at the expense of those who have the least, and of the middle classes that dream – ever more vainly – of hoisting themselves into the cocoon of the present financial oligarchy, Kempf maintains.

That’s why, he says, we must “bring down the rich” rather than pull up the poor, in order to begin to respect the thresholds of irreversible deterioration of the planet’s resources.

He takes aim, finally, at the concept of sustainable development and the alibi it now constitutes for governments and companies that use it to justify other drains on resources in the name of this new rationale that is supposedly harmless for the planet. Sustainable development, he writes, has become “a semantic weapon to remove the dirty word, ‘ecology.’”Is there any need, moreover, to still develop France, Germany or the United States? The concept has meaning, he concluded, but only in poorer countries, because it can help them to avoid a development as brutal and lawless as the one we have effected in the West. In the West, the first of our environmental responsibilities “consists of reducing our consumption of material goods” to attain a level of well-being based on values and knowledge, in sum, on immaterial, but nonetheless very real, riches.

Metrolight has developed a new kind of ballast that not only extends the life of the lamp, but also makes industrial lighting more efficient.
A big green light for Israel's Metrolight
By Karin Kloosterman

January 24, 2008

Cities and companies in the US are concerned about energy usage. Not only does consuming excessive electricity to cover lighting costs for streetlights and stores, affect the bottom line, it also takes a toll on the environment.

Now Netanya-based company Metrolight has a "green" lighting solution that will be easier on the accounting books and also the earth. The company has engineered a lighting control system that prolongs the life of industrial high-intensity discharge (HID) lights, while making them more efficient at the same time.

HID lights are the most common type of lights used in city streetlights. They are also found in grocery stories and shopping malls. Brighter than fluorescent, HID lights suffer quickly from wear and tear, via an igniting and operating mechanism known as a ballast.



Through its flagship product, the Smart Electronic Ballast, Metrolight has developed a new kind of ballast that not only extends the life of the lamp, but which can make industrial lighting more efficient. Up to 65 percent more efficient, the company says.

Metrolight has been in the business since 1996, and after seeing the success of its product in the global marketplace, it now has a bold ambition of reducing America's (and the world's) total energy consumption by three percent. This equals the CO2 pollution emitted by 65 million cars, and millions - if not billions - of dollars in savings.

The company claims to have already saved its customers about $6.5 million.

"We are selling energy savings," says Metrolight's CTO Jonathan Hollander, who has helped develop the ballast. He explains that the traditional magnetic ballasts used in HID lights, quickly reduce the output of the light by about 50 percent. To compensate, as a rule, light designers install lights that are stronger than necessary.

This is wasteful, reasons Hollander. "Light designers know this and will overshoot," he tells ISRAEL21c.

To keep the HID light strong and long lasting, the core of Metrolight's solution is its ballast, which controls the light ignition process slowly, by not destroying the electrode, says Hollander. In technical-speak he says: "We operate the lamp with a high frequency regime."

According to a 2002 US Department of Energy report, lighting amounts to about 22 percent of all electricity used in America. Of that, HID lights account for 26 percent of lighting energy, or about six percent of the total energy used in lighting. If Metrolight can save up to 65 percent of six percent, the company estimates about three percent of America's total energy costs can be conserved.

Cities in the US are using the solution, so is the Tenafly Racquet Club in New Jersey and the Carlsberg beer factory in Israel. Metrolight reports that some 250 thousand ballasts have been installed in locations around the world.

"When we realized that what we do has the potential to save energy, this was something that we were excited about," says Hollander. "We want to save three percent of the world's energy. That is a huge amount of savings. We are concerned about the world we live in and try to minimize damage, and Metrolight is an effective way to do that."
