The World's Rubbish Dump: A Garbage Tip that Stretches from Hawaii to Japan

Kathy Marks

A "plastic soup" of waste floating in the Pacific
Ocean is growing at an alarming rate and now covers an area twice the
size of the continental United States, scientists have said.

vast expanse of debris - in effect the world's largest rubbish dump -
is held in place by swirling underwater currents. This drifting "soup"
stretches from about 500 nautical miles off the Californian coast,
across the northern Pacific, past Hawaii and almost as far as Japan.

Moore, an American oceanographer who discovered the "Great Pacific
Garbage Patch" or "trash vortex", believes that about 100 million tons
of flotsam are circulating in the region. Marcus Eriksen, a research
director of the US-based Algalita Marine Research Foundation, which Mr
Moore founded, said yesterday: "The original idea that people had was
that it was an island of plastic garbage that you could almost walk on.
It is not quite like that. It is almost like a plastic soup. It is
endless for an area that is maybe twice the size as continental United

Curtis Ebbesmeyer, an oceanographer and leading
authority on flotsam, has tracked the build-up of plastics in the seas
for more than 15 years and compares the trash vortex to a living
entity: "It moves around like a big animal without a leash." When that
animal comes close to land, as it does at the Hawaiian archipelago, the
results are dramatic. "The garbage patch barfs, and you get a beach
covered with this confetti of plastic," he added.

"soup" is actually two linked areas, either side of the islands of
Hawaii, known as the Western and Eastern Pacific Garbage Patches. About
one-fifth of the junk - which includes everything from footballs and
kayaks to Lego blocks and carrier bags - is thrown off ships or oil
platforms. The rest comes from land.

Mr Moore,
a former sailor, came across the sea of waste by chance in 1997, while
taking a short cut home from a Los Angeles to Hawaii yacht race. He had
steered his craft into the "North Pacific gyre" - a vortex where the
ocean circulates slowly because of little wind and extreme high
pressure systems. Usually sailors avoid it.

was astonished to find himself surrounded by rubbish, day after day,
thousands of miles from land. "Every time I came on deck, there was
trash floating by," he said in an interview. "How could we have fouled
such a huge area? How could this go on for a week?"

Moore, the heir to a family fortune from the oil industry, subsequently
sold his business interests and became an environmental activist. He
warned yesterday that unless consumers cut back on their use of
disposable plastics, the plastic stew would double in size over the
next decade.

Professor David Karl, an
oceanographer at the University of Hawaii, said more research was
needed to establish the size and nature of the plastic soup but that
there was "no reason to doubt" Algalita's findings.

all, the plastic trash is going somewhere and it is about time we get a
full accounting of the distribution of plastic in the marine ecosystem
and especially its fate and impact on marine ecosystems."

Karl is co-ordinating an expedition with Algalita in search of the
garbage patch later this year and believes the expanse of junk actually
represents a new habitat. Historically, rubbish that ends up in oceanic
gyres has biodegraded. But modern plastics are so durable that objects
half-a-century old have been found in the north Pacific dump. "Every
little piece of plastic manufactured in the past 50 years that made it
into the ocean is still out there somewhere," said Tony Andrady, a
chemist with the US-based Research Triangle Institute.

Moore said that because the sea of rubbish is translucent and lies just
below the water's surface, it is not detectable in satellite
photographs. "You only see it from the bows of ships," he said.

to the UN Environment Programme, plastic debris causes the deaths of
more than a million seabirds every year, as well as more than 100,000
marine mammals. Syringes, cigarette lighters and toothbrushes have been
found inside the stomachs of dead seabirds, which mistake them for food.

is believed to constitute 90 per cent of all rubbish floating in the
oceans. The UN Environment Programme estimated in 2006 that every
square mile of ocean contains 46,000 pieces of floating plastic,

Eriksen said the slowly rotating mass of rubbish-laden water poses a
risk to human health, too. Hundreds of millions of tiny plastic
pellets, or nurdles - the raw materials for the plastic industry - are
lost or spilled every year, working their way into the sea. These
pollutants act as chemical sponges attracting man-made chemicals such
as hydrocarbons and the pesticide DDT. They then enter the food chain.
"What goes into the ocean goes into these animals and onto your dinner
plate. It's that simple," said Dr Eriksen.
