The missing ocean plastic sink: Gone with the rivers

(University of Barcelona) Plastics are a growing problem for natural ecosystems around the globe, and in particular for marine and freshwater environments. Rivers are the leading source of plastic pollution, as it has been estimated that they deliver several million metric tons of plastic annually to oceans from poor land-based waste management. The estimates made for plastics flowing from the rivers are tens to hundreds of times higher than the quantity of plastics floating on the ocean's surface.
