Microplastics—tiny plastic fragments less than five millimeters in size—are ubiquitous in the global ocean. In fact, an estimated eight million tons of plastics enter our oceans each year, yet only one percent can be seen floating at the surface. Where the rest ends up is not well understood.
What are the health risks?
Marine animals like scallops and oysters ingest microplastics, and are later consumed by humans. As microplastics make their way through the food chain, do they pose a health risk to animals and humans?
