Microplastics, defined as plastic particles smaller than 5mm, are a well-known marine pollutant. An estimated 93,000 to 236,000 metric tons of microplastics litter the world's oceans, according to a 2015 study. Recent evidence suggests that they also contaminate freshwater environments, the food we eat, and even the air we breathe. Yet the consequences for human health are largely unknown.
