Microplastics found in cave system closed to humans for 30 years

[Still Waters]

Water and sediment in the Cliff Cave system, Missouri, are contaminated with microplastics, scientists studying student-collected samples have found. 

Reports of microplastic contamination are depressingly common these days, even in the most remote places. What makes this finding exceptional, however, is that no one has been able to enter the system for three decades prior to the research being conducted. Our least-wanted products are reaching places we cannot.
