Future Rememberance

A few million years from now they'll be an interesting fossil record for our android inheritors.



Sea of Trash

...A 55-year-old lawyer with a monkish haircut, glasses that look difficult to break, an allergy of the eyes that makes him squint and a private law practice in Anchorage, Pallister spends most of his time directing a nonprofit group called the Gulf of Alaska Keeper, or GoAK (pronounced GO-ay-kay). According to its mission statement, GoAK’s lofty purpose is to “protect, preserve, enhance and restore the ecological integrity, wilderness quality and productivity of Prince William Sound and the North Gulf Coast of Alaska.” In practice, the group has, since Pallister and a few like-minded buddies founded it in 2005, done little else besides clean trash from beaches. All along Alaska’s outer coast, Chris Pallister will tell you, there are shores strewn with marine debris, as man-made flotsam and jetsam is officially known. Most of that debris is plastic, and much of it crosses the Gulf of Alaska or even the Pacific Ocean to arrive there.

The tide of plastic isn’t rising only on Alaskan shores. In 2004 two oceanographers from the British Antarctic Survey completed a study of plastic dispersal in the Atlantic that spanned both hemispheres. “Remote oceanic islands,” the study showed, “may have similar levels of debris to those adjacent to heavily industrialized coasts.” Even on the shores of Spitsbergen Island in the Arctic, the survey found on average a plastic item every five meters.

Back in the 1980s, the specter of fouled beaches was a recurring collective nightmare. The Jersey Shore was awash in used syringes. New York’s garbage barge wandered the seas. On the approach to Kennedy Airport, the protagonist of “Paradise,” a late Donald Barthelme novel, looked out his airplane window and saw “a hundred miles of garbage in the water, from the air white floating scruff.” We tend to tire of new variations on the apocalypse, however, the same way we tire of celebrities and pop songs. Eventually all those syringes, no longer delivering a jolt of guilt or dread, receded from the national consciousness...


I'm sure a little corporate Mockingbird had something to do with that.

...Not even oceanographers can tell us exactly how much floating scruff is out there; oceanographic research is simply too expensive and the ocean too varied and vast. In 2002, Nature magazine reported that during the 1990s, debris in the waters near Britain doubled; in the Southern Ocean encircling Antarctica the increase was a hundredfold. And depending on where they sample, oceanographers have found that between 60 and 95 percent of today’s marine debris is made of plastic.

Plastic gets into the ocean when people throw it from ships or leave it in the path of an incoming tide, but also when rivers carry it there, or when sewage systems and storm drains overflow. Despite the Ocean Dumping Reform Act, the U.S. still releases more than 850 billion gallons of untreated sewage and storm runoff every year, according to a 2004 E.P.A. report. Comb the Manhattan waterfront and you will find, along with the usual windrows of cups, bottles and plastic bags, what the E.P.A. calls “floatables,” those “visible buoyant or semibuoyant solids” that people flush into the waste stream like cotton swabs, condoms, tampon applicators and dental floss.

The Encyclopedia of Coastal Processes, about as somniferously clinical a scientific source on the subject as one can find, predicts that plastic pollution “will incrementally increase through the 21st century,” because “the problems created are chronic and potentially global, rather than acute and local or regional as many would contemplate.” The problems are chronic because, unlike the marine debris of centuries past, commercial plastics do not biodegrade in seawater. Instead, they persist, accumulating over time, much as certain emissions accumulate in the atmosphere. The problems are global because the sources of plastic pollution are far-flung but also because, like emissions riding the winds, pollutants at sea can travel.

And so, year after year, equipped with garbage bags and good intentions, the volunteers in the International Coastal Cleanup fan out, and year after year, in many places the tonnage of debris is greater than before. Seba Sheavly, a marine-debris researcher who ran the I.C.C. until 2005, says the Ocean Conservancy’s cleanup “has never been about curing the problem of marine debris.” It has always been, she told me, “a public awareness campaign.” Now a private consultant to the plastics industry and the United Nations Environment Program, among other clients, Sheavly says she believes that the primary value of coastal cleanups lies in the lesson they teach volunteers — “that what they’re picking up comes from them.” On Alaska’s outer coast, however, only a fraction of the debris washing in comes from local litterbugs. On much of Alaska’s 33,000-mile shoreline, in fact, there are no local litterbugs. On much of Alaska’s shoreline there are no people at all.

When Pallister took me there last July, a GoAK crew had been at work for two weeks cleaning up Gore Point (population: 0), part of a 400,000-acre maritime wilderness at the heart of the Kenai Fjords. Despite the pretty scenery, few nature lovers bother to visit. You can travel to Gore Point only by helicopter, seaplane or boat, and then only when weather permits, which it often does not. In the lower 48, beach cleanups tend to involve schoolchildren gleaning food wrappers and cigarette butts left by recreational beachgoers. GoAK’s cleanups, by contrast, are costly expeditions into the wild. The group’s volunteers must be 18 or older, and all must sign a frightening waiver in which they agree not to hold the organization liable for perils like “dangerous storms; hypothermia; sun or heat exposure; drowning; vehicle transportation and transfer; rocky, slippery and dangerous shorelines; tool and trash related injuries; bears; and” — in case that list left anything out — “other unforeseen events.”

The windward shore of Gore Point is what’s known among beachcombers and oceanographers as “a collector beach.” In 1989, according to The Anchorage Daily News, more of Exxon’s spilled oil ended up there than on any other beach on Alaska’s outer coast, but unlike the oil, the incoming debris never ended. Every tide brings more. Over the course of several decades, ever since the dawn of the plastics era, a kind of postmodern midden heap accumulated behind the driftwood berm. To beachcombers in the know, Gore Point was a happy hunting ground, one of the best places in Alaska to find exotic oddities. To Pallister, it was a paradise lost. Now, subsidized by a $115,000 matching grant from the National Oceanic and Atmospheric Administration (N.O.A.A.), he had embarked upon a possibly quixotic mission to regain it...

In its first summer in action, GoAK managed to clean 350 miles of rugged shoreline, picking up enough trash to fill 46 trash-hauling bins. Pallister wasn’t satisfied. It wasn’t enough to clean beaches near coastal communities. And so, last summer, Gore Point became a front line in the federal government’s campaign against debris. What would it take, Pallister hoped to learn, to clean up one wild beach?

To me, Gore Point seemed like the scene of an unsolved environmental mystery — unsolved and possibly unsolvable. Who, if anyone, can be held accountable for all that plastic trash? What, if anything, does it forebode for us and for the sea?

...Pallister has a theory about where all this trash comes from. “There’s a weather phenomenon we have here,” he told me in Anchorage. “A winter low sets this prevailing wind pattern that will just funnel this way for days on end if not weeks on end. That wind is blowing right across that bunch of plastic out there.” The “bunch of plastic” he was talking about is the flotilla of trash, purportedly at least as big as Texas, that has accumulated at the becalmed heart of the North Pacific Subtropical Gyre, a giant clockwise circuit of currents that revolves between East Asia and North America.

High-pressure systems like the one that predominates over the North Pacific Subtropical Gyre force currents to spiral inward. Oceanographers call these spirals “convergence zones.” Low atmospheric pressure systems like the one that predominates over the Gulf of Alaska have the opposite effect, creating “divergence zones” where the surface currents move outward toward shore. Divergence zones tend to expel debris. Convergence zones collect it.



In 2001 a peer-reviewed scientific journal called The Marine Pollution Bulletin published a study, whose undramatic title, “A Comparison of Plastic and Plankton in the North Pacific Central Gyre,” belied its dramatic findings. The lead author — a sailor, environmentalist, organic farmer, self-trained oceanographer and onetime furniture repairman named Charles Moore — went trawling in the North Pacific convergence zone about 800 miles west of San Francisco and found seven times as much plastic per square kilometer as any previous study.

“As I gazed from the deck at the surface of what ought to have been a pristine ocean,” Moore later wrote in an essay for Natural History, “I was confronted, as far as the eye could see, with the sight of plastic. It seemed unbelievable, but I never found a clear spot. In the week it took to cross the subtropical high, no matter what time of day I looked, plastic debris was floating everywhere: bottles, bottle caps, wrappers, fragments.” An oceanographic colleague of Moore’s dubbed this floating junk yard “the Great Pacific Garbage Patch,” and despite Moore’s efforts to suggest different metaphors — “a swirling sewer,” “a superhighway of trash” connecting two “trash cemeteries” — “Garbage Patch” appears to have stuck.

The Garbage Patch wasn’t merely a cosmetic problem, nor merely a symbolic one, Moore contended. For one thing, it was a threat to wildlife. Scientists estimate that every year at least a million seabirds and 100,000 marine mammals and sea turtles die when they entangle themselves in debris or ingest it. “Entanglement and ingestion, however, are not the worst problems caused by the ubiquitous plastic pollution,” Moore wrote. Plastic polymers, as has long been known, absorb hydrophobic chemicals, including persistent organic pollutants, or POPS, like dioxin, P.C.B.’s and D.D.T. Highly controlled in the U.S. but less so elsewhere, such substances are surprisingly abundant at the ocean’s surface. By concentrating these free-floating contaminants, Moore worried, particles of plastic could become “poison pills.” He also worried about toxins in the plastic itself — phthalates, organotins — that have been known to leach out over time. Once fish or plankton ingest these pills, Moore speculated, poisons both in and on the plastic would enter the food web. And since such toxins concentrate, or “bioaccumulate,” in fatty tissues as they move up the chain of predation — so that the “contaminant burden” of a swordfish is greater than a mackerel’s and a mackerel’s greater than a shrimp’s — this plastic could be poisoning people too.



...The hardest question to answer about the Garbage Patch, it turns out, isn’t whether plastic threatens animals and ecosystems, but what, if anything, can be done about it. “We haven’t been able to hatch up any good ideas,” Flint admitted. Albatross chicks don’t forage on land, she said. In fact they don’t forage at all. Their parents do, flying far and wide across the Pacific, swooping down to snatch morsels off the surface, which they bring back home and regurgitate into a hungry chick’s mouth. That’s where all the detritus in that Greenpeace ad came from. Even if we were to clean every beach in the world, it wouldn’t keep albatrosses from stuffing their offspring full of plastic. “You’d have to clean the entire ocean,” Flint said...

“That’s not unusual,” Charles Moore told me, when I described the midden at Gore Point. “Any windward side of an island’s going to have situations like that. The question is, how much can we take? We’re burying ourselves in this stuff.” Moore sympathized with Pallister’s motives, and said that GoAK’s efforts could help “raise awareness.” But if Pallister thought he was saving Gore Point from plastic pollution, he was fooling himself. “It’s just going to come back,” Moore said.

This, in Moore’s opinion, is why the 2006 Marine Debris, Research, Prevention and Reduction Act is likewise doomed to fail. “It’s all been focused on cleanups,” he says of federal policy. “They think if they take tonnage out of the water, the problem will go away.”

In the Northwestern Hawaiian Islands, whose shores are washed by the southern edge of the Garbage Patch, federal agencies are staging one of the biggest marine-debris projects in history. Since 1996, using computer models, satellite data and aerial surveys, they have located and removed more than 500 metric tons of derelict fishing gear in hopes of saving endangered Hawaiian monk seals from entanglement. The results have been mixed at best. Biologists are now finding fewer monk seals entangled in debris; but they are also finding fewer monk seals, period. Meanwhile, an estimated 52 tons of fresh debris inundates the Northwestern Hawaiian Islands every year.

Along with financing and volunteers, corporate sponsors of the International Coastal Cleanup contribute homilies about saving the planet. “Working together we help keep our coasts clean,” ran Coca-Cola’s contribution to the I.C.C.’s 2006 report. Marine debris, declared Dow Chemical, is a “people problem that we, the citizens of the world, have the power to stop.” Is it? Yes, says Moore, but “there is no magic bullet,” and the solutions may require sacrifices that the citizens, governments and corporations of the world are reluctant to make. Eventually we will have to abandon planned obsolescence, and instead manufacture products that are durable, easily recyclable or both, Moore said. And we will have to overcome our addiction to conspicuous consumption...


Fat chance of that occurring...

...As nearly everyone I spoke to about marine debris agrees, the best way to get trash out of our waterways is, of course, to keep it from entering them in the first place. But experts disagree about what that will take. The argument, like so many in American politics, pits individual freedom against the common good. “Don’t you tell me I can’t have a plastic bag,” Seba Sheavly, the marine-debris researcher, says, alluding to plastic-bag bans like the one San Francisco enacted last year. “I know how to dispose of it responsibly.” But proponents of bag bans insist that there is no way to use a plastic bag responsibly. Lorena Rios, an environmental chemist at the University of the Pacific, says: “If you go to Subway, and they give you the plastic bag, how long do you use the plastic bag? One minute. And how long will the polymers in that bag last? Hundreds of years.”

“The time for voluntary measures has long since passed,” says Steve Fleischli, president of Waterkeeper Alliance, a network of environmental watchdogs to which, it should be noted, the Gulf of Alaska Keeper does not belong. (Waterkeeper officials have objected to GoAK’s use of their brand, but Pallister insists that their objections are without legal merit. “They’ve trademarked ‘Riverkeeeper,’ ‘Soundkeeper,’ ‘Baykeeper,’ ” he told me, “but not ‘Alaska keeper.’ ”) Fleischli would have us tax the most pervasive and noxious plastic pollutants — shopping bags, plastic-foam containers, cigarette butts, plastic utensils — and put the proceeds toward cleanup and prevention measures. “We already use a portion of the gasoline tax to pay for oil spills,” Fleischli says. Such levies shouldn’t be seen as criminalizing the makers and sellers of plastic disposables, he argues; they merely force those businesses to “internalize” previously hidden costs, what economists call “externalities.” This market-based approach to environmental regulation, known as extended producer responsibility, is increasingly popular with environmental groups. By sticking others with the ecological cleaning bill, the thinking goes, businesses have been able to keep the price of disposable plastics artificially low. And as Pallister learned at Gore Point, the cleaning bill may be greater than we can afford.

We still have limited tax dollars to spend and scarier nightmares to fear. No one — not Pallister, not Moore — will tell you that plastic pollution is the greatest man-made threat our oceans face. Depending whom you ask, that honor goes to global warming, agricultural runoff or overfishing. But unlike many pollutants, plastic has no natural source and therefore there is no doubt that we are to blame. Because we can see it, plastic is a powerful bellwether of our impact upon the earth. Where plastics travel, invisible pollutants — pesticides and fertilizers from lawns and farms, petrochemicals from roads, sewage tainted with pharmaceuticals — often follow. Last June, shortly before my voyage in the Opus began, Sylvia Earle, formerly N.O.A.A.’s chief scientist, delivered an impassioned speech on marine debris at the World Bank in Washington. “Trash is clogging the arteries of the planet,” Earle said. “We’re beginning to wake up to the fact that the planet is not infinitely resilient.” For ages humanity saw in the ocean a sublime grandeur suggestive of eternity. No longer. Surveying the debris on remote beaches like Gore Point, we see that the ocean is more finite than we’d thought. Now it is the sublime grandeur of our civilization but also of our waste that inspires awe...


"Sublime grandeur..."?

Upon grim reflection, I wonder if a limited nuclear war in the early 1950s (just enough to collapse the System) might in the long term have been better for the planet than what really (or in our timeline) happened.

Alas, like any War of the Ring where the object of power is not utterly destroyed, it would only have led to a time where the shadow grew anew in a different form.

What I fear is that somewhere some idiot like Doug Feith is talking to some other orcish fools about how a "limited" nuclear war now would "be better" for the world.

It's one solution to global warming and the blight on the face of the world. Not a proper solution, for the reasons Professor Tolkien outlined so well.
