Based on a recent study, human activity has resulted in a global plastic cycle, which is similar to natural cycles like the carbon cycle, in which plastic moves through the atmosphere, seas, and soil. According to one physicist, the result is the planet's "plastification."

"People should be worried about airborne microplastics," Stohl said. For one, they will inhale it, which will almost certainly have health consequences. Second, since the environment is an excellent dealer. It transports plastic particles to places we don't want them, including farm areas, national parks, lakes, the Arctic, and even Antarctica. We would eventually have incredibly high concentrations of plastics all over the place."

From the summit of Mount Everest to the deepest seas, microplastic waste has been discovered. Scientists characterized the discovery of tiny plastic particles in human placentas in December as "a matter of great concern."
