eat. That styrofoam under the chicken breasts you just bought; those green plastic chairs out on your deck; the clear plastic bottle of Coke in your hand—or, even more so, its red plastic cap. Sooner or later, much of these plastics are going to find their way into one of the five major
oceanic gyres: be it the north Pacific, the south Pacific, the north Atlantic, the south Atlantic, or the Indian Ocean.
If you live in the western United States, the
Great Pacific Garbage Patch (aka the Pacific Trash Vortex) is where your trash is likely to end up (though much of the garbage is also made up of debris jettisoned from ships). Estimates of the size of this gyre vary greatly—ranging from the size of Texas to twice the size of the Continental United States—since any estimate will depend on the degree of plastic concentration used to define the affected area.
Whatever the size of the Great Pacific Garbage Patch, however, we can all agree that it is scary. Really scary. Especially for creatures living in and around the Hawai‘ian Islands, since most debris that manages to escape from the gyre eventually makes its way down here. The coast along the Ka‘ū desert near the southern tip of the Big Island (the southern-most point in the United States), in particular, seems to be a magnet for this marine litter.
Our marine biologist friend Bill Gilmartin is the co-founder of the
Hawai‘i Wildlife Fund, a non-profit organization “dedicated to the conservation of Hawaii’s native wildlife through research and education,” comprised of “educators, conservationists, researchers, naturalists, communities, volunteers and donors devoted to the conservation of Hawaii’s fragile marine ecosystem and its inhabitants.” The HWF conducts beach clean-ups every few months along the Ka‘ū coastline, and when Bill invited me to participate in one such clean-up last week, I gladly accepted.
I spent the night before the event at Bill’s home in Volcano (he cooked some delicious spicy meatballs and angel-hair pasta for our dinner, washed down by several bourbons and ginger ale), and at six-thirty the next morning we drove down the mountain to the sea. There had been a tremendous rain storm during the night, and we were greeted by the sight of a snow-covered Mauna Loa lit up by a bright pink sunrise:

Thirty-seven volunteers met at a parking lot near Naʻālehu, and our fearless leader Megan Lamson filled us in on where we’d be picking up debris, and the logistics of the day’s activities:

Next, everyone piled into the various four-wheel-drive vehicles that folks had brought with them, and we bumped and bounced our way down a dirt track through cattle-grazing country to the coastline.
Out came the garbage bags, and we set to work. My group started at Ka‘alela and headed south, and another group started at Pa‘akea and worked their way north. The plan was to meet in the middle at Kamilo Point for lunch, and to discuss cleanup finds and load the pickups with the debris we had collected.
There wasn’t a whole lot of trash to begin with. My very first find was rather odd: a collection of some half-dozen different-colored pencil erasers, their hues greatly diminished by the salt water. Here we are picking our way over the lava rocks, filling our black bags with trash:

After about a half an hour, however, we came across a stretch of beach absolutely covered with debris:

There were gigantic shards of broken and unidentifiable plastic items (mostly blue and white, I noted); hundreds of small, black, conical, plastic fish-traps; and enormous hunks of fish net and rope:
yours truly, with the debris in the backgroundThis stretch of litter-infested beach went on for about a quarter of a mile, and we all quickly filled our bags to over-flowing. The problem was that the road—where we were to leave the full bags for later pick-up—was a good walk from the beach, so we had to schlepp our finds over the rocks and ankle-catching shrubs. Not an easy task.

Finally it was lunch time. We convened at the mid-way point, where the other group had collected together a varied assortment of interesting items, including some Japanese boundary stakes; a small glass float; several computer circuit boards; a few brown speckled (bird?) eggs; a scuba cylinder; a motorcycle helmet; a cigarette lighter from Hong Kong; some liquor bottles made in Japan and Scotland; a very old tube television set; and various car tires.

adding the day’s catch of rope and net
to the previously-collected pile at the landfill(that’s Bill in the cap)In all, we collected in the three hours we worked on the beach 1,500 pounds of derelict fish net and rope, and 2,410 pounds of non-net/rope marine debris (including 66 XL full trash bags). Tired but content, we sat around eating our lunches, and discussed the morning’s work:

As I sat munching my cheese and
homemade kimchee sandwich, I noticed that the sand at my feet was not the usual color. As I focused my eyes on it more clearly, I realized that the reason for this was that it was not just sand. It was, in fact, mostly tiny pieces of broken plastic, mixed with the sand and black lava rock:

Bill explained to me that the plastic in the ocean continually breaks up into smaller and smaller pieces, but it never disintegrates entirely. It just turns into this “plastic sand,” which continues to float in the water, and is ingested by sea birds and other aquatic creatures.
Here’s a photo of the half pound of plastic that was found in the dead body of a fledgling Laysan albatross:
And here’s another close-up view of the tropical Hawai‘ian beach where we had our lunch:

And then it hit me. This wasn’t just about picking up litter along the coastline. We would never be able to completely clean it up, no matter how many people we were and how often we went, since tons of new debris were continually washing ashore.
No. My horror at the tiny bits of plastic scattered everywhere about my feet made me realize: This was about education. People like me need to actually see it to really get it. Only then will we have a chance of stopping the plastic madness that has become our modern world.
