Greenpeace experts and volunteers carry out plastic waste pollution monitoring at the Russian coasts and coastal waters of the Baltic Sea. They assessed the level of contamination of the water surface, as well as the coast in two areas: the Curonian spit (Kurshskaya kosa) — a UNESCO world heritage site, and in the Gulf of Finland— where the resort area with five million St. Petersburg inhabitants is located. Found artifacts were weighed, sorted into categories and counted.
