Tiny pieces of plastic, known as microplastics, are filling the Earth's atmosphere and have been discovered raining down on US national parks like the Grand Canyon. The study focused on US national parks and protected wildness areas but it is expected this type of plastic pollution could be found around the world. Rocky Mountain National Park had the greatest amount microplastics among the national parks and wilderness areas in the study. For the study the team looked at the source and life history of wet and dry microplastic deposits found in these parks. The ongoing deposit of plastic in wilderness areas and national parks has the potential to influence these ecosystems, the team say.
