Microplastics have been discovered in a remote area of the French Pyrenees mountains. The particles travelled through the atmosphere and were blown into the once pristine region by the wind, according to a new study published in Nature Geoscience.
This is just the latest example of the “hidden risks” posed by plastics that humans cannot see with the naked eye. For now, governments and activists are focused on avoiding plastic litter in the environment, driven mainly by concern for wildlife and worries over unsightly drinks bottles or abandoned fishing nets on beaches. Plastic bag usage has been cut in many parts of the world, and various projects are exploring how to gather up the floating plastic waste in oceans. But little has yet been done to deal with polluting plastic particles that are usually invisible.
