Preface. There have been thousands of articles since I published this back in 2003.
Today I read a surprising study that claims glass is more harmful than plastic because it is mined from rare materials and requires more fossil fuels to produce and ship (Brock 2020). Yet far more plastic is produced a year, 380 million tonnes, versus 209 million tonnes of glass.
Plastic in the news:
2021 ‘Biodegradable’ plastic will soon be banned in Australia—that’s a big win for the environment. Biodegradable plastic implies it is made plant materials, and will break down into natural components after it is discarded. But many are made from fossil fuels with chemical additives that break the plastic fragment into micro-plastics, still polluting land and water. And they often don’t break down faster than traditional plastics. And don’t throw “compostable plastic” into your home compost (or recycling bin for that matter), they’re meant only for industrial composting where very high temperatures are reached.

Friedemann A. 15 Feb 2003. The largest oil spill on Earth: Plastic in the Oceans. EnergyResources.
I had a disturbing experience at Cape Canaveral National Sea Shore last month. I drove to the north end of the park, and walked south along the beach towards the enormous towers of the Kennedy Space Center, 11 miles away. On the left, the sparkling blue water was punctuated with the tall white plumes of pelicans dive-bombing the waves.
On the right was Mosquito lagoon, one of the most beautiful places in Florida.
I’d come to find Sea Beans. These are beautiful exotic seeds of tropical plants from all over the world, with names like Hog-plum, Hamburger Bean, and Moonflower (http://www.seabean.com/guide/index.htm).
But what I found was plastic trash. Miles and miles of soda bottles, plastic bags, milk jugs, plastic spoons, and the like. At the Ponce Inlet Marine Science Center, the docent was sure most of it came from party boats and cruises offshore. Case solved-– cruise ships have been caught dumping their shit, literally, into the pristine waters of Alaska. Not surprising to find out they’re throwing trash overboard as well.
My career as trash detective would have ended then if I hadn’t seen an ad in the paper for a lecture on “How plastic trash finds its way into the ocean” at the Berkeley Public Library on February 11, 2003, where I heard Charles Moore speak.
The problem is huge — what I would call largest oil spill in the world since most plastic is made out of oil, not natural gas or coal.
Much of this is out of date in 2021, but for historical purposes, back then:
Between California and Asia there’s ten million square miles of plastic swirling in the slow rotation of the north pacific gyre, an area larger than Africa. A huge mountain of air, heated over the equator, creates the currents as it moves north. The garbage on this marine merry-go-round spends 12 years completing one circle. About half of the plastic made is close to the specific gravity of water, and the half that sinks easily rises again when storms mix the water up.
There’s so much plastic in the Pacific gyre, that six times as much plastic as zooplankton by weight was found there (Marine Pollution Bulletin). Outside the gyres, the concentration is almost half that amount – still awfully high.
Like diamonds, plastics are forever. Plastic doesn’t biodegrade. It takes even longer for the sun to break apart a piece of plastic in the ocean than on land, because the water cools the plastic down. Although it gets broken into smaller and smaller pieces, it reaches a point where the molecular weight and tight chemical bonds prevent any organism from breaking it down further.
Plastic facts
- One hundred billion pounds of pre-production plastic resin pellets are produced every year in the US to create consumer plastics.
- These pellets, also known as nurdles, look just like fish eggs, and are the most common plastic object found in the ocean. Clearly many of them are escaping the production process.
- Only 3.3% of plastic is recycled, because reheating plastic reduces its flexibility. Sixty-three pounds of plastic per person ends up in landfills in the United States.
- Because plastic is lighter than sand, it may be eroding beaches
- Plastic concentrates chemicals and pollutants up to one million times their concentration in the surrounding sea water. Many of these chemicals are endocrine disruptors.

Trashing the Oceans by Thomas Hayden
An armada of plastic rides the waves, and sea creatures are suffering
http://www.mindfully.org/Plastic/Ocean/Trashing-Oceans-Plastic4nov02.htm
At Taco Bell on Main Street in Ventura, Calif., you can take out the chalupa of your choice–Baja, Nacho Cheese, or Supreme, with ground beef, chicken, or steak. But it will always come in a small plastic shopping bag. The bags arrive preprinted from a factory in Asia–usually. One brilliant summer morning in 2000, the small private research vessel Alguita discovered a 10-mile-wide flotilla of the disposable sacks, an estimated 6 million of them destined for Taco Bells around the country, bobbing more than 1,000 miles west of the Ventura store. “We were out in the middle of the Pacific, where you would think the ocean would be pristine,” recalls the Alguita’s captain, Charles Moore. “And instead, we get the Exxon Valdez of plastic-bag spills.”
Most plastic bags end up in landfills, part of the millions of tons of plastic garbage Americans dump each year. But whether jettisoned illegally by ships at sea, washed out from land during storms, or, as in the case of the chalupa bags, accidentally lost overboard from containerships, countless tons of plastic refuse end up drifting on the high seas.
Lethal litter.
Many Americans know about the hazard posed by six-pack rings, the plastic yokes that can grasp a seagull or otter’s neck as tightly as they do a soda can. But researchers are finding that plastic litter doesn’t just strangle wildlife or spoil the view. “Plastic is not just an aesthetic problem,” says marine biologist David Barnes of the British Antarctic Survey. “It can actually change entire ecosystems.
The largest pieces of plastic–miles long discarded fishing nets and lines– take an obvious toll. These “ghost nets” snare and drown thousands of seals, sea lions, and dolphins a year. Researchers have also watched in horror as hungry turtles wolf down jellyfish-like plastic bags and seabirds mistake old lighters and toothbrushes for fish, choking when they try to regurgitate the trash for their starving chicks. As Barnes is documenting, tiny marine animals riding rafts of plastic trash are invading polar seas, while Japanese researchers are finding high concentrations of deadly chemicals clinging to floating, tapioca-size plastic pellets called “nurdles.” And Moore, back from a three-month North Pacific voyage last week, is tracking it all and discovering that tiny fragments of plastic are entering the food web right near its bottom.
A member of the prominent Los Angeles-area Hancock Oil family, Moore is anything but a typical researcher. He grew up as an avid surfer and sailor in a comfortable waterfront home in Long Beach and ran a furniture restoration business. But in 1995, at the age of 48, Moore sold his business, set up the Algalita Marine Research Foundation, and designed a unique double-hulled sailing research vessel, the Alguita. Both ship and captain found their true calling after a 1997 yacht race to Hawaii.
On his return voyage, Moore veered from the usual sea route and saw an ocean he had never known. Every time he stepped out on deck, “there were shampoo caps and soap bottles and plastic bags and fishing floats as far as I could see. Here I was in the middle of the ocean, and there was nowhere I could go to avoid the plastic.” Ever since, Moore has dedicated his time, and a small personal fortune, to seeking it out. “It’s an overlooked problem, and this guy is making a really important contribution,” says oceanographer Dale Kiefer of the University of Southern California.
With little scientific training, Moore formed alliances with professional scientists, including chemists, biologists, and a private oceanographer, Curtis Ebbesmeyer, himself a well-known flotsam hunter. Ebbesmeyer’s most famous case involved a 1990 containership spill that dumped 80,000 Nike running shoes into the North Pacific. The errant runners washed up on beaches from British Columbia to California, helping him trace the currents that carried them.
The Alguita’s mission started in earnest in 1999. Moore and his all-volunteer crew–attracted by the chance for meaningful adventure and Moore’s reputation as an excellent chef–returned to the garbage-strewn region he had happened on two years earlier and skimmed the surface with fine collecting nets. Across hundreds of miles of ocean, they counted roughly a million pieces of plastic per square mile, almost all of it less than a few millimeters across.
Trash heap.
The Alguita was sampling water beneath a climate feature called the North Pacific subtropical high–the big “H” on weather maps–that protects Southern California’s enviable weather by pushing storms north or south. The H is the eye of a circle of currents thousands of miles wide called the North Pacific gyre. The high’s weak winds and sluggish currents naturally collect flotsam, earning it the unfortunate nickname of the “Eastern Garbage Patch.” Similar wind and current patterns exist in all the major oceans, and all presumably suffer from similar contamination.
Because most plastics are lighter than seawater, they float on the surface for years, slowly breaking down into smaller and smaller fragments–which often end up in the ocean’s drifting, filter-feeding animals, like jellyfish. Early in his voyages, Moore collected baseball-size gelatinous animals called salps and found their translucent tissues clogged with bits of monofilament fishing line and nurdles (more romantically referred to as “mermaid tears” by beachcombers). A hundred billion pounds of these pellets are produced each year, to be formed into everything from cd cases to plastic pipe. But each one is a perfect plankton’s-eye-view replica of a fish egg. “You rarely find any particles smaller than a millimeter in the water,” says Moore. “They’re all in the jellies.”
That’s not likely to be good for the filter feeders or the things that eat them, notes Moore, and not just because a meal of plastic doesn’t yield much nutrition. A 2001 paper by Japanese researchers reported that plastic debris can act like a sponge for toxic chemicals, soaking up a millionfold greater concentration of such deadly compounds as pcbs and dde, a breakdown product of the notorious insecticide ddt, than the surrounding seawater. That could turn a bellyful of plastic from a mere stomachache to a toxic gut bomb that can work its way through the food web.
Unhappy hunting.
In Moore’s latest voyage to the garbage patch, he got a close-up view of what happens when life meets floating garbage. The Alguita’s crew found plastic trash bobbing in a thick line from horizon to horizon–everything from tiny particles to 5-inch-thick towing lines, Japanese traffic cones, and yellow quart bottles of American crankcase oil. “We followed the debris for more than a mile, and we never found the end of it,” Moore told U.S. News by satellite phone. The research team had stumbled across what oceanographers call a Langmuir cell, a wind-driven circulation pattern where two masses of water are pushed together, forcing some of the water to sink where they meet; anything that floats stays on the surface.
Normally that means living things. These convergences are favorite hunting grounds of seabirds and other predators, which pick zooplankton, fish eggs, jellyfish, and other delicacies out of the long, frothy windrows. Alien-seeming gelatinous creatures usually float just below, spinning fantastic webs of mucus to sieve out every last particle. Not this time, says Moore. “We found all the refuse of civilization, but there were no zooplankton at all.” He’s at a loss to explain why.
The Alguita team did see albatrosses and tropic birds circling above the line of trash. With little else to choose, they were apparently eating plastic. The birds seemed to be picking and choosing “the reds and pinks and browns. Anything that looks like shrimp,” Moore says. Earlier in the trip, the Alguita had visited the French Frigate Shoals, off Hawaii, home to endangered monk seals and seabird rookeries. In the birds’ gullets, researchers found red plastic particles.
Lines of trash like this one may also help explain the woes of the monk seals, which are usually killed by large masses of nets, more than any one fishing vessel is likely to lose or cut loose at a time. The Alguita’s crew plucked several of these net balls from the Langmuir windrow. The converging currents evidently brought nets together and tangled them into makeshift deathtraps as they rolled in the sinking water.
Expect the trashing of the oceans to continue. An international convention called MARPOL bans the dumping of plastics at sea, but enforcement on the open ocean is nonexistent. Accidental losses are forgiven, notes Moore, and shippers don’t even have to report them. “That means dogooders like me don’t even get a chance to clean up after the polluters,” says Moore.
Rob Krebs of the American Plastics Council notes that people value plastics for exactly what creates problems at sea: their durability. Manufacturers are not to blame for the trash, he says. “The responsibility is with the people who control the material, not those who produce it.” Moore agrees that greater efforts to prevent spills will help. But, he adds, “there’s no reason why a six-pack ring or a peanut butter jar should have to last for 400 years.” Manufacturers have tried for years to perfect biodegradable packaging, and at least one company, EarthShell, may finally be making some headway. Government agencies like the National Park Service are already using EarthShell’s biodegradable plates and packaging, and hundreds of McDonald’s restaurants have experimented with its clamshell boxes.
Moore, meantime, says he’ll keep hunting marine plastic as long as his money holds out. After all, there is a link between his own advantages and the plastic flotsam he has been tracking. Oil made his grandfather’s fortune–and oil is the raw material for most plastics manufacturing. “In a way, part of all this is remediation for the consequences of my grandfather’s life,” he says. “I guess maybe I need to make amends.”
Preface. The article below makes the case for the hazards of one of these enormous ships running aground or sinking, blocking a major shipping line, leaking oil, and possibly impossible to salvage.
