The Arctic is generally considered to be of the most pristine environment left on Earth, free from the touch of human hands but this isn’t really the case as even there they’ve found plastic and rubber particles in the snow so guess that leaves nothing at all we haven’t touched.
Scientists collected snow in jars and just looked at them. Some of the particles were really, really small making them impossible to identify as to where they came from. To be fair, all sorts of things were found in the snow, varnish and synthetic fibers as well. But the amount of microplastics was truly startling.
They believe that the particles came on the wind through the atmosphere and rained back down as snow. All of this just goes to show how large the problem is and how important it is that we are aware of it and make changes so that overtime, it can lessen.
