There are now 46000 pieces of plastic per square kilometre of the world's oceans killing a million seabirds and 100000 marine mammals each year. Worse still there seems to be nothing we can do to clean it up. So how do we turn the tide? Way out in the Pacific Ocean, in an area once known as the doldrums, an enormous, accidental monument to modern society has formed. Invisible to satellites, poorly understood by scientists and perhaps twice the size of France, the Great Pacific Garbage Patch is not a solid mass, as is sometimes imagined, but a kind of marine soup whose main ingredient is floating plastic debris. ...
'There's no such thing as a pristine sandy beach any more,' Charles Moore says. 'The ones that look pristine are usually groomed, and if you look closely you can always find plastic particles. On Kamilo Beach in Hawaii there are now more plastic particles than sand particles until you dig a foot down. On Pagan Island
they have what they call the "shopping beach". If the islanders need a cigarette lighter, or some flip-flops, or a toy, or a ball for their kids, they go down to the shopping beach and pick it out of all the plastic trash that's washed up there from thousands of miles away.'
