Pacific Trash Gyre

Like the falcons turning and turning in a widening gyre in William Butler Yeats poem “The Second Coming,” common plastic, perhaps as much as three million tons, swirls in a Pacific Ocean gyre.

Dubbed the Pacific Trash Vortex, plastic, floats, bobs and semi-sinks in this stagnant part of the sea that is wind-starved and hard to escape. Currents propel the colorful flotsam until it reaches this part of the sea known as the doldrums, a place sailors avoid. Once in it, the North Pacific Sub-Tropical Gyre goes round and round in an area twice the size of Texas, the southern tip perhaps five hundred miles north of Honolulu. The gyre, like gravity, does not release easily.

Run-off from the Ganges River in India, the San Gabriel River in Los Angeles and a thousand other rivers and beaches in North America and Asia feed the trash vortex with a steady diet of billions and billions of pounds of plastic each year that it devours but cannot digest.

Petroleum based plastics do not bio-degrade, they photo-degrade into smaller and smaller pieces. Every piece of this type of plastic still exists. Approximately 95 per cent of the world’s annual 300 billion pound pre-production plastic is petroleum based.

Plastic from as far back as the 1940’s, when this miracle material’s modern epoch began, tricks birds and fish, luring them in with a myriad of color, replicating something like their favorite meal, choking many and poisoning most, leaving a wake of death behind.

In 2003, Charles Moore, founder of the Algalita Marine Research Foundation of Los Angeles sailed through the gyre and wrote, “I was confronted as far as the eye could see with the sight of plastic.”

Moore recently sampled seawater inside the vortex and found that for every six pounds of plastic, only one pound of naturally growing plankton occurred.

Moore has been studying the Northern Fulmars, a bird like the albatross that spends most of its life at sea.. They are washing ashore in the Pacific Islands dead and full of plastic at an alarming rate. Petroleum based plastics are high in PCB’s, a toxin that enters the food chain and effects the hormonal structure of all that consume it.

“The actual ability to wipe out the entire vertebrate kingdom in the ocean is with the plastic particles,” Moore said.

Curt Ebbesmeyer, an oceanographer, who specializes in ocean flotsam, recently sorted through the stomach of a dead albatross on the island of Guam. Cigarette lighters, bottle caps and hundreds of other plastics were found in its belly including a war relic; a Bakelite tag from a WWII US Navy patrol that’s been floating for sixty years.

Ebbesmeyer said, “If you could fast forward 10,000 years and do an archeological dig, a core sample down through the beach, you'd find a little line of plastic," he says. "What happened to those people? Well, they ate their own plastic and disrupted their genetic structure and weren't able to reproduce. They didn't last very long because they killed themselves.”

And Yeats, who predicted a calamity in his poem that would spawn the “second coming” probably never thought it would be an every day material.

Getting the Ocean's mass in perspective

As scientist Jim Lovelock observed, "Although the weight of the Oceans is 250 times that of the atmosphere, it is only one part in 4,000 of the weight of the Earth."

1/4000 = 0.00025

Therefore, only 0.025% of Earth's mass is Water. Yet we tend to think of our Oceans as a vast and endless resource, free to everyone.

Scientists also point out, "If the Earth were a globe 12 inches in diameter, the average depth of the ocean would be no more than the thickness of a piece of paper, and even the Deepest Ocean Trench would only be a tiny dent, one third of a millimeter deep. (0.3 mm = 0.01 in)

Since the Ocean's mass is 0.025% that of Earth's mass, our Oceans can more accurately be appreciated as the priceless public reservoirs they are, the only living Oceans in the entire universe. Mars might have some frozen mud.

Knowing the Earth's "surface" is 70.8% water, often leads a popular conclusion... there might be more Ocean than Earth.

Unfortunately, this popular "solution" is legal and leads to a global assumption... that pollution might be absorbed and simply rendered harmless... within the Ocean's vastness.

Millions of Tons of toxic chemicals are discarded into rivers worldwide, while the industry leaders "cross their fingers" in a futile false hope that the chemicals will quietly be absorbed by the living Oceans.

To compound the problem, millions of tons of plastic, also dumped 24/7, by the barge load, into our Oceans, does not "break down" for almost 1000 years, but it does break into tiny bits of plastic "dust" or "snow. Then the PCB's, that are now major contaminants in the Ocean, are attracted to the plastic bits like a magnetic sponge. Marine animals can't differentiate the plastic snow from plankton, so they eat the plastic bits, and become toxic with PCB's, causing immune system failure.

As the toxins slowly distribute worldwide by the Ocean's conveyer belt currents, the entire food chain is affected, from the tiny coral polyps that make world's largest reefs, to whales feeding on plankton and other particles suspended in the water column, including PCB laden plastic "snow".

An impairment to the immune systems of living creatures is being observed globally, from the tiny coral polyps, to the giant killer whales, and finally the humans themselves, seated at the top of the food chain, consuming industrial leftovers that will not bio-degrade in nature for thousands of years.

ATSDR points out that every child born from a mother who consumed Great Lakes fish during their pregnancies were three times (3X) more likely to have lower IQs and twice (2X) as likely to be TWO grade levels in reading comprehension behind their peers. Other studies have shown children who's mothers consumed PCB-contaminated fish had lower birth rates, reduced motor reflexes and neuromuscular function, poor short-term and long-term memory, weakened immune systems and greater susceptibility to infections, among other problems.

Now tons of the sludge from water treatment plants, containing PCB's, are being dumped onto agricultural land. Scientists are scrambling just to name the new diseases as they discover them and counting the countless number of species that just became extinct, and the oil emperors fiddle in the stock market while making world record profits.

I know this is hard to believe, it was for me also, so Google it.

As a free nation... we the people... have spent more of our own tax dollars for exploring remote space and the mud on Mars than protecting the only "Living Oceans" in the entire universe while the planet become less inhabitable for humans. Who is really steering this over-heating planet, big business persons? Is bowing to the $tock market index given a higher priority than the World's Ocean Health index in Washington?

As we awaken to the collapse of our Oceans, we begin to see the consequences of giving the "green light" to industry for dumping millions of tons of "known toxins" into the only known living Oceans in the entire universe.

At age thirteen, Jacques-Yves Cousteau's book, "The Silent World" was presented to me by my scuba instructor, when I was first certified as a scuba diver. I was thrilled with swimming and breathing underwater, enjoying a view of nature referred to as the "Silent World."

Today, Jacques-Yves Cousteau must be looking down on the Oceans, and the dying coral reefs, with salty tears in his eyes.

Captain Larry,

Thanks ur comments. Dig ur website too. Gore's got that comment ride on.

Took my children to the Corpus Christi coast right after the hurricane blew through B'ville, about ninety miles south, this week. There was so much churned up at the beach... Red-brown froth - toxic I'm sure being down river from one of the biggest petro-chemical complexes in the world. What does that say about our society - allowing this coast to stink in a brown industrial half-light. And me dumb enough to let my kids wade in the crap for an instant, thinking that there's no way, its a beach, its a state park - but its Texas and its run by oil and lets get the hell out of this filth.

Rant -

Of course adaption is part of the evolutionary process... Did you say that most Americans contain at least 150 different industrial chemicals in their bodies? Or was that in the essay on the Pacific Trash Vortex?

If we really knew how toxic our world was, I think, though I'm not sure, there would be a little more pressure on politicians to regulate and punish those that make profit
from trashing everybody's world...
