Plastic In Oceans Statistics

Plastic is still pouring into the ocean at an estimated 32% of global plastic waste being mismanaged in 2016, feeding land based leakage that reaches from the Mediterranean surface to the Arctic and beyond, where tens of trillions of particles float. The page connects those particle counts with real impacts on wildlife and money, weighing ecosystem costs of $8 to $13 billion per year against cleaner waste management that can cut leakage and save over $125 million annually in some scenarios.

About 40 trillion plastic particles are estimated to be floating at the ocean surface right now, a figure that helps explain why beaches, fisheries, and even remote currents keep finding new contaminants. Yet the sources of that plastic often start far inland, where 32% of global plastic waste was mismanaged in 2016 and roughly 87% of marine debris is traced back to land. In this post, we piece together where the leakage comes from, how much reaches different regions, and what it is doing to marine life.
