Microplastics Are Literally Raining from the Sky—Even in Remote Mountains

3. Microplastics in the Rocky Mountains

Recent research in the Rocky Mountains has revealed significant amounts of microplastics in rainwater and snow samples from areas far removed from civilization.
The presence of these particles, despite the lack of local plastic sources, points directly to the long-distance transport of pollution via atmospheric processes.
Even protected and seemingly untouched wilderness is now affected by the global spread of microplastics.
