Twenty years ago, a team of U.K. scientists sounded the alarm on a then-underappreciated problem: the breakdown of plastic litter into small, even microscopic, fragments. While many previous reports had documented the buildup of plastic bottles and bags in the natural environment, much less attention had been paid to what the scientists dubbed “microplastics.”
Due to “the rapid increase in plastic production, the longevity of plastic, and the disposable nature of plastic items,” the researchers concluded that there was “considerable potential” for microplastic pollution to become a major problem for the environment and human health.
It turns out, they were right.
Over the past two decades, the rate of plastic production has roughly doubled, to more than 400 million metric tons per year, about the weight of 1,200 Empire State Buildings. In the same time period, microplastics — defined as particles with a diameter less than 5 micrometers, about the width of a human hair — have exploded into the public consciousnes... Read more
