'Invisible' microplastics spread in skies as global pollutant

Airborne microplastics, too small to be seen, are spreading globally, even reaching human bodies, prompting concern among researchers. Studies reveal their presence in skies, rain, snow, and human bodies, potentially influencing extreme weather. Researchers, like Hiroshi Okochi from Waseda University, are investigating the origins and impacts of these pollutants. Microplastics in the air could induce cloud formation and emit greenhouse gases when degraded by UV rays. Efforts to mitigate exposure include forest absorption, with hopes pinned on fast-growing trees like paulownia to combat airborne microplastics.
