Since the mass production of plastics began in the 1940s, the versatile polymers have spread rapidly across the globe. Although plastics have made life easier in many ways, disposing of the materials is a growing problem. Now, researchers in the ACS journal Environmental Science & Technology estimate that the average American consumes more than 70,000 particles of microplastics per year, though the health effects of that consumption are unclear.
