Reducing Plastic Pollution Key to Stabilizing Ocean Microplastics Levels

The study, a collaboration between researchers at Imperial College London and GNS Science, suggests that reducing plastic pollution by 5% per year would stabilize the level of microplastics – plastics less than 5 mm in length – in the surface oceans.
