There are now 46,000 pieces of plastic per square kilometre of the world's oceans, killing a million seabirds and 100,000 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.
Floating beneath the surface of the water, to a depth of 10 metres, was a multitude of small plastic flecks and particles, in many colours, swirling like snowflakes or fish food The world's navies and commercial shipping fleets make a significant contribution throwing some 639,000 plastic containers overboard every day, along with their other litter |
I know this is an old story, but like the plastic and trash we keep throwing away, it just won’t go away.
Measurements show there is six times more plastic than plankton in this area.
Plastic does not biodegrade; no microbe has yet evolved that can feed on it.
Prolonged exposure to sunlight causes polymer chains to break down into smaller and smaller pieces, a process accelerated by physical friction, such as being blown across a beach or rolled by waves.
Worldwide, according to the United Nations Environment Programme, plastic is killing a million seabirds a year, and 100,000 marine mammals and turtles.
Bottle caps, pocket combs, cigarette lighters, tampon applicators, cottonbud shafts, toothbrushes, toys, syringes and plastic shopping bags are routinely found in the stomachs of dead seabirds and turtles.
Every single molecule of plastic that has ever been manufactured is still somewhere in the environment, and some 100 million tons of it are floating in the oceans.
