Image shows microplastics (top right: white-colored polypropylene sheet, bottom right: transparent polyethylene sheet) found in Indonesian salt samples. A study called “Global Pattern of Microplastics (MPs) in Commercial Food-Grade Salts" found positive correlations between microplastics in seawater and microplastics in sea salts which people consume everyday. Greenpeace is urging corporations around the world to reduce and eventually phase out single-use plastics.
