A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a study published March 8, 2023 in the open-access journal PLOS ONE by Marcus Eriksen from The 5 Gyres Institute, USA, and colleagues. Understanding plastic accumulation in the oceans to date could provide a critical baseline to help address this form of pollution. Previous studies have focused primarily on northern-hemisphere oceans near the world’s most industrialized nations, while other studies have found increases in ocean plastic over shorter time periods. In this study, Eriksen and colleagues looked at data on ocean-surface-level plastic pollution collected between 1979-2019 from 11,777 stations across six marine regions (...
