Tiny particles of plastic are seemingly everywhere: So-called microplastics have been found in the ocean, tap water, bottled water, soil and the air we breathe. Microplastics in the oceans are ingested by aquatic life and enter the food chain. Indeed, microplastics have been detected in seafood, including tuna, lobster and oysters. Humans are also likely exposed to microplastics as a result of plastic contamination from food packaging or processing.
