Our oceans are not only home to large pieces of plastic, but also to minute plastic particles, called microplastics. Researchers now know that microplastic particles can be found in all sea regions, even in arctic sea ice.
Once in the ocean, all plastic trash eventually breaks down into tiny pieces. Many of these are lighter than water and float on the sea's surface. Over time, exposure to sunlight and wave movements create miniscule plastic pieces, which sometimes end up inside the stomachs of fish.
