LOS ANGELES (The New York Times) – The world is awash in plastic. It’s in our cars and our carpets, we wrap it around the food we eat and virtually every other product we consume; it has become a key lubricant of globalization — but it’s choking our future in ways that most of us are barely aware.

I have just returned with a team of scientists from six weeks at sea conducting research in the Great Pacific Garbage Patch — one of five major garbage patches drifting in the oceans north and south of the Equator at the latitude of our great terrestrial deserts. Although it was my 10th voyage to the area, I was utterly shocked to see the enormous increase in the quantity of plastic waste since my last trip in 2009. Plastics of every description, from toothbrushes to tires to unidentifiable fragments too numerous to count floated past our marine research vessel Alguita for hundreds of miles without end. We even came upon a floating island bolstered by dozens of plastic buoys used in oyster aquaculture that had solid areas you could walk on.

Plastics are now one of the most common pollutants of ocean waters worldwide. Pushed by winds, tides and currents, plastic particles form with other debris into large swirling glutinous accumulation zones, known to oceanographers as gyres, which comprise as much as 40 percent of the planet’s ocean surface — roughly 25 percent of the entire earth.

No scientist, environmentalist, entrepreneur, national or international government agency has yet been able to establish a comprehensive way of recycling the plastic trash that covers our land and inevitably blows and washes down to the sea. In a 2010 study of the Los Angeles and San Gabriel Rivers, my colleagues and I estimated that some 2.3 billion pieces of plastic — from polystyrene foam to tiny fragments and pellets — had flowed from Southern California’s urban centers into its coastal waters in just three days of sampling.

The deleterious consequences of humanity’s “plastic footprint” are many, some known and some yet to be discovered. We know that plastics biodegrade exceptionally slowly, breaking into tiny fragments in a centuries-long process. We know that plastic debris entangles and slowly kills millions of sea creatures; that hundreds of species mistake plastics for their natural food, ingesting toxicants that cause liver and stomach abnormalities in fish and birds, often choking them to death. We know that one of the main bait fish in the ocean, the lantern fish, eats copious quantities of plastic fragments, threatening their future as a nutritious food source to the tuna, salmon, and other pelagic fish we consume, adding to the increasing amount of synthetic chemicals unknown before 1950 that we now carry in our bodies.

We suspect that more animals are killed by vagrant plastic waste than by even climate change — a hypothesis that needs to be seriously tested. During our most recent voyage, we studied the effects of pollution, taking blood and liver samples from fish as we searched for invasive species and plastic-linked pollutants that cause protein and hormone abnormalities. While we hope our studies will yield important contributions to scientific knowledge, they address but a small part of a broader issue.

The reality is that only by preventing synthetic debris  — most of which is disposable plastic — from getting into the ocean in the first place will a measurable reduction in the ocean’s plastic load be accomplished. Clean-up schemes are legion, but have never been put into practice in the garbage patches. [more]

Choking the Oceans With Plastic

    Hi Des,

    I know you do not get a lot of comments on here, but many of us are reading you every day. The news you are posting is extremely urgent. I hope you keep doing this.

    There are 400 - 500 "dead zones" now in the world's oceans. The plastic debris undoubtedly contributes to these regions, as plastics flow from rivers to oceans.

    Humanity is destroying itself. Humanity doesn't care enough to stop. I suspect Nature will respond with increasing levels of violence (death and destruction) against us. Life (including microbiological life such as viruses) have a way of doing that.

    Earth balance will be restored. We will be gone. It will take several hundred thousand years to restore the balance (at least), but only about 50 years to wipe out mankind.

    We're going to see this destruction on mankind - in our lifetimes.

    I totally agree with the previous comment.
    Des, thank you for your hard work. Especially, since I believe it must be regularly breaking your heart.
