This indicates a serious contamination of nature with this material.
Scientists from the University of Canterbury in Great Britain collected samples of snow fallen near the Ross Glacier in Antarctica. It turned out to be contaminated with microplastics, indicating a serious problem.
Even remote areas of Antarctica have been found to be contaminated. Scientists think it got to the South Pole by air.
Plastic is a harmful material. It affects human health by getting into the body, and it also absorbs solar energy, reducing the reflectivity of snow and thus contributing to global warming.
