Scientists recently found tiny plastic fibers just below the summit of Mount Everest, one of Earth’s tallest and most-inaccessible mountains. The findings were published in the journal One Earth.
"These are the highest microplastics discovered so far," Imogene Napper, a scientist studying plastic accumulation at the University of Plymouth, said in a statement.
In a remote, high-altitude lake in the Pyrenees mountains in southern France, scientists found sand-grain-sized plastics and tiny plastic fibers.
