An Ocean of Plastic Soup

Most of us have walked along a beach and seen the inevitable plastic flotsam. (I saw too much of it at our local community beach this past weekend during glorious spring weather.) This miracle of packaging and convenience endures for generations in our landfills and in festering view in our seas.

The largest area of this disgusting waste is a "plastic soup" floating in the Pacific Ocean twice the size of the continental United States.

"The 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."

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.

Another oceanographer 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."

'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.

He 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?"'
