Junk journey highlights plastic soup of Pacific

swanksalot0 comment

One of these days we’ll have to do something about the sea of plastic polluting the ocean.

Sailing 4,000 miles on the Pacific Ocean made Marcus Eriksen and Joel Paschal sick. It wasn’t waves that turned their stomachs, but the amount of plastic garbage they encountered on a voyage with the Algalita Marine Research Foundation earlier this year.

The activists wanted more people to share their disgust about plastic litter that swirls, relatively unexplored, in continent-size patches of ocean.

To that end, they have built a motor-less craft from 15,000 recycled beverage bottles, fishing nets, and the cockpit of a Cessna, and are sailing it more than 2,000 miles from southern California to Hawaii. They left Long Beach, Calif., on Sunday.

We are all affected by global pollution, whether we realize it or not.

 

On the last Pacific voyage that ended in February, Eriksen and Paschal helped marine researcher Charles Moore assess the extent of pollution in the waters leading up to the Great Pacific Garbage Patch, a swirling mass of plastic debris some estimate to be as large as the United States.

In early tests, a sample showed 48 parts of plastic to each part of plankton.

“They haven’t finished processing the samples, but there was an exponential increase in the plastic,” said Anna Cummins, who was also aboard and serves as Algalita’s education adviser. “What looked on the surface like clean water, when you pulled it up, it looked like plastic soup. It was disgusting.”

Algalita researchers said the floating, soupy landfill isn’t well understood because satellites can’t spot the translucent particles. And although efforts by scientists to explore plastic in five gyres around the world have been lacking, interest is expanding as the public learns more.

“No one really knows what’s out in the other gyres,” Cummins said. “In the north Pacific alone there’s Capt. Moore with his research boat. We are a small organization with five or six paid staff members.”

Eighty percent of the plastic comes not from ships but from land, where tossed consumer goods eventually travel from beaches and rivers into the ocean, according to Algalita.

Plastic concentrates poisons such as PCBs at levels a million times higher than found in the water, according to Japanese researchers.

I had only heard of one gyre, five is even worse. Maybe we should test putting Daniel Burd’s decomposition microorganism in one of the gyres.

Clean Coal is not cheap

Failure of leadership means money for desert wars, not for reducing carbon emissions.

For years, scientists have had a straightforward idea for taming global warming. They want to take the carbon dioxide that spews from coal-burning power plants and pump it back into the ground.

President Bush is for it, and indeed has spent years talking up the virtues of “clean coal.” All three candidates to succeed him favor the approach. So do many other members of Congress. Coal companies are for it. Many environmentalists favor it. Utility executives are practically begging for the technology.

But it has become clear in recent months that the nation’s effort to develop the technique is lagging badly.

In January, the government canceled its support for what was supposed to be a showcase project, a plant at a carefully chosen site in Illinois where there was coal, access to the power grid, and soil underfoot that backers said could hold the carbon dioxide for eons.

Perhaps worse, in the last few months, utility projects in Florida, West Virginia, Ohio, Minnesota and Washington State that would have made it easier to capture carbon dioxide have all been canceled or thrown into regulatory limbo.

Coal is abundant and cheap, assuring that it will continue to be used. But the failure to start building, testing, tweaking and perfecting carbon capture and storage means that developing the technology may come too late to make coal compatible with limiting global warming.

“It’s a total mess,” said Daniel M. Kammen, director of the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley.

Lets hope Obama’s friendship with energy companies like Exelon won’t impede research funds into cleaner coal when he wins in 2009.

But only a handful of small projects survive, and the recent cancellations mean that most of this work has come to a halt, raising doubts that the technique can be ready any time in the next few decades. And without it, “we’re not going to have much of a chance for stabilizing the climate,” said John Thompson, who oversees work on the issue for the Clean Air Task Force, an environmental group.

The fear is that utilities, lacking proven chemical techniques for capturing carbon dioxide and proven methods for storing it underground by the billions of tons per year, will build the next generation of coal plants using existing technology. That would ensure that vast amounts of global warming gases would be pumped into the atmosphere for decades.

The highest-profile failure involved a project known as FutureGen, which President Bush himself announced in 2003: a utility consortium, with subsidies from the government, was going to build a plant in Mattoon, Ill., testing the most advanced techniques for converting coal to a gas, capturing pollutants, and burning the gas for power.

Seems like besides a failure of political leadership, energy companies are milking taxpayer funds for their own purposes.

More Plastic Water Bottle Blues

Do Not Attempt This At Home

That’s it, I’m sticking with beer, wine and Jameson’s from now on…..

Alina Tugend writes:

The type of plastic bottle that typically holds water, soda and juice is made from polyethylene terephthalate, a petroleum-based material also known as PET that is labeled No. 1.

The trouble with reusing those plastic bottles is that each time they are washed and refilled they become a little more scratched and crinkly, which can lead them to degrade. That can cause a trace metal called antimony to leach out, said Frederick S. vom Saal, a professor of biology at the University of Missouri who has studied plastics for years.

But perhaps a better alternative — in terms of health and the environment — is to use the hard plastic bottles made with polycarbonate plastic, often known by the brand Nalgene. It has the numeral 7 stamped at the bottom and is the same type of material used to make some baby bottles, the lining of tin cans and other products. I have some of those around the house. They are just too big to fit into our car cup holders so I retired them to the basement.

Time to dig them out?

Not quite. Environmental groups and some scientists have raised concern that such plastic can leach bisphenol A, an endocrine-disrupting chemical.

Which plastic bottle to use then? Can’t always count on having the


“Sigg Samurai Spirit Water Bottle” (Sigg)

“If I was to use plastic, I would stay with No. 2 and No. 5,” Professor vom Saal said. No. 2 is high-density polyethylene; No. 5 is polypropylene. Both are used in margarine tubs and yogurt containers for example.

But, he warned, do not heat anything in any type of plastic in the microwave.

If you do use these hard No. 7 plastic bottles, the Green Guide, published by the National Geographic Society, advises you to avoid washing them in a dishwasher or with harsh detergent to limit wear and tear.

China Bags

The Pope gets bagged

Interesting development, especially since most of the plastic bags issued by US retailers are manufactured in China.

The Chinese government says it is banning shops from handing out free plastic bags from June this year, in a bid to curb pollution.
Production of ultra-thin plastic bags will also be banned, the State Council said in a statement.

Instead, people will be encouraged to use baskets or reusable cloth bags for their shopping, the council said.

The council also called for greater recycling efforts from rubbish collectors, and suggested financial authorities should consider higher taxes on the production and sale of plastic bags. [From BBC NEWS | Asia-Pacific | China announces plastic bag ban]

If China does in fact start taxing the bag manufacturers, will this encourage more US retailers to consider other options, like cloth bags? Hemp bags?

Bush Censors Climate Reports

Seth Anderson0 comment

Speaking about Bush crony-corruption (aren’t we always?), climate change science also was a target of the heavy hand of the Assministration. Following the Bush playbook, oil industry hacks were placed in positions of authority, and manipulated every bit of data they could to obfuscate global warming reports.

Congressional hearing heats up over changes to climate reports – Los Angeles Times


Government scientists, armed with copies of heavily edited reports, charged Monday that the Bush administration and its political appointees had soft-pedaled their findings on climate change.The accusations led Democrats and Republicans at the congressional hearing to accuse each other of censorship, smear tactics and McCarthyism.

To underscore their charges of the administration’s oil-friendly stance, Democrats grilled an oil lobbyist who was hired by the White House to review government climate change documents and who made hundreds of edits that the lawmakers said minimized the impact of global warming.“You were a spin doctor,” Rep. John A. Yarmuth (D-Ky) told the lobbyist.

Henry Waxman is doing his job well:

The House Committee on Oversight and Government Reform hearing was marked by an open confrontation between Chairman Henry A. Waxman (D-Los Angeles) and the ranking Republican, Rep. Darrell Issa (R-Vista) — a rare display of direct debate in otherwise carefully choreographed hearings.

The hearing was the latest effort to challenge what the Democratic congressional majority sees as the Bush administration’s unchecked use of power. In the past few weeks, Democrats have held inquiries or announced plans to examine the unmonitored use of national security letters that allow the government to spy on Americans, the dismissal of U.S. attorneys and the identifying of former covert CIA operative Valerie Plame, among other issues.

Waxman has been particularly aggressive, pursuing inquiries about intelligence in the lead-up to the Iraq war and the politics of global warming.

To support their charges Monday, the Democrats produced hundreds of pages of legal depositions, exhibits and e-mail exchanges between administration officials. The paper trail illustrated how officials with no scientific training shaped the administration’s climate change message and edited global warming reports, inserting doubt in the place of definitive statements and diminishing the role people play in the planet’s rising temperatures.

Waxman’s committee received more than eight boxes of papers from the White House Council on Environmental Quality that he said provided disturbing indications of political interference.

“There may have been a concerted effort directed by the White House to mislead the public about the dangers of global climate change,” said Waxman, who also cited the administration practice of “controlling what federal scientists could say to the public and the media about their work.”

“It would be a serious abuse if senior White House officials deliberately tried to defuse calls for action by ensuring that the public heard a distorted message about the risks of climate change,” Waxman said.
