One disconcerting consequence of our huge plastic pollution problem is that we really have no idea where the stuff can end up. The latest locale to surprise scientists looking into such matters is the Arctic, who say that snowfall there is bringing tiny fragments of plastic along for the ride.
The insidious spread of microplastics through our environment is something that we really don't know enough about. Researchers have now found unexpected quantities of the material lodged in Arctic sea ice, shedding new light on how they move through the ocean.
