4. Plastic Showers in the Pyrenees
In a pattern echoing discoveries in the Rockies, scientists have found microplastics in the Pyrenees, a remote mountainous border between France and Spain.
Rain and wind carried these synthetic particles from far-off urban centers, with prevailing winds acting as the main delivery system.
This evidence reinforces the idea that microplastic pollution is a truly global phenomenon, transcending regional boundaries and industrial zones.
