This National Geographic article asks why does the Arctic have more plastic than most places on Earth? Plastics travel on ocean currents and through the air to the far north and accumulate—sometimes inside the animals that live there.
Here in the Arctic, hundreds of miles from the nearest big city, are some of the greatest loads of plastics on the planet. Studies find higher concentrations of microplastics in sea ice in these remote, high-latitude hotspots than in the five infamous ocean garbage patches. And a recent report finds airborne microplastics are falling on the far north mixed with snow.
