Microplastics are very small pieces of plastic that pollute the environment.[54] Microplastics are not a specific kind of plastic, but rather any type of plastic fragment that is less than 5 mm in length according to the U.S. National Oceanic and Atmospheric Administration (NOAA) [55][56] and the European Chemicals Agency.[57] They enter natural ecosystems from a variety of sources, including cosmetics, clothing, and industrial processes.
