Trillions of Plastic Pieces May Be Trapped In Arctic Ice
sciencehabit (1205606) writes "Humans produced nearly 300 million tons of plastic in 2012, but where does it end up? A new study has found plastic debris in a surprising location: trapped in Arctic sea ice. As the ice melts, it could release a flood of floating plastic onto the world. From the article: 'Scientists already knew that microplastics—polymer beads, fibers, or fragments less than 5 millimeters long—can wind up in the ocean, near coastlines, or in swirling eddies such as the Great Pacific Garbage Patch. But Rachel Obbard, a materials scientist at Dartmouth College, was shocked to find that currents had carried the stuff to the Arctic.'"
nearly 300 million tons of plastic in 2012 [...] reaching 288 million tonnes in 2012

Estimates of how much of that production has been trapped in Arctic ice provided in the article:
- "[some of] much of [the total amount of plastic produced]"
- "more than 1 trillion pieces of plastic"
- "abundances of hundreds of ['fragments less than 5 millimeters long' selected using a microscope] per cubic meter"
Would have really hurt to estimate the weight of those fragments? One plastic bag could easily end up as a million pieces of plastic. About one plastic bag or 10 grams of plastic per 10.000 cubic meters sounds a lot less dramatic, I guess.
Plastics that are still in visible pieces are nuisance, and all oceans have tons and tons and TONS of plastic based flotsam - I worked as a sailor before and even in the middle of a big ocean we saw plastic garbage floating
But the real danger are those teeny tiny plastic particles
Most plastic breaks down after prolonged exposure to sunlight, and they kept breaking apart as time goes by, until they became teeny tiny plastic (polymer) particles which inevitably end up in the food-chain (sea creatures - little fishes - bigger fishes - entrees in restaurants - people's stomach) and sooner and later all of us start eating food containing plastic particles
Yes, even those so-called bio-degradable plastics only degrade until they become teeny tiny polymer particles, and then stop degrading
What kind of problem will those plastic particles do to our health ? Anybody knows ?
