Trillions of Plastic Bits, Swept Up by Current, Littering Arctic Waters

"The world’s oceans are littered with trillions of pieces of plastic — bottles, bags, toys, fishing nets and more, mostly in tiny particles — and now this seaborne junk is making its way into the Arctic.

In a study published Wednesday in Science Advances, a group of researchers from the University of Cádiz in Spain and several other institutions show that a major ocean current is carrying bits of plastic, mainly from the North Atlantic, to the Greenland and Barents seas, and leaving them there — in surface waters, in sea ice and possibly on the ocean floor.

Because climate change is already shrinking the Arctic sea ice cover, more human activity in this still-isolated part of the world is increasingly likely as navigation becomes easier. As a result, plastic pollution, which has grown significantly around the world since 1980, could spread more widely in the Arctic in decades to come, the researchers say."
