Microplastics, loosely defined as plastic pieces smaller than 5 millimeters across, or roughly the size of a small grain of rice, have made their mark on both the global ecosystem and the popular consciousness, famously killing seabirds and raining down on wilderness areas.

And while the impacts of ocean microplastics have been the subject of significant media and scientific attention, researchers say that most microplastics are actually accumulating on land, including agricultural areas.

One estimate suggested that 107,000 to 730,000 tons of microplastics could be dumped onto agricultural soils in the U.S. and Europe every year, compared to the 93,000 to 236,000 tons that enter the oceans.
