19 Aug 2019 --- Microscopic plastic fibers identified in rainwater samples from the rural Rocky Mountain National Park, further highlighting the ubiquitous nature of plastic fibers and particles - commonly referred to as microplastics. Gregory Wetherbee, the study author, notes that the findings show that the pollution of plastic fibers is not just an urban condition and that they are everywhere – in our air, water and soil. Moving forward, the author calls for better methods for sampling, identification, and quantification of plastic deposition along with the assessment of potential ecological effects. Wetherbee’s concluding note: “It is raining plastic.”
