Maps of floating plastic

The National Geographic has created new maps showing the extent of floating plastic in the ocean:
Tens of thousands of tons of plastic garbage float on the surface waters in the world’s oceans, according to researchers who mapped giant accumulation zones of trash in all five subtropical ocean gyres. Ocean currents act as “conveyor belts,” researchers say, carrying debris into massive convergence zones that are estimated to contain millions of plastic items per square kilometer in their inner cores.
