From Mount Everest to the Mariana Trench, in freshly fallen Antarctic snow and even in our blood –plastic is everywhere. Plastic waste makes up 80% of all marine pollution, and microplastics were found in every marine turtle, over half of all whales, and a third of seals examined in studies published in 2018-2019. Yet, despite this growing crisis, only 9% of all plastic ever produced has been recycled, with the vast majority ending up in landfills or the environment. To protect the ocean and human health, we must drastically reduce plastic pollution. As part of the #OceanDecade, scientists are developing solutions to prevent plastic from entering the ocean — a first step towards reducing the impact of plastic on marine ecosystems. Watch our video for three examples of pioneering initiatives stopping plastic pollution at the river level, and read more about these inspiring initiatives in the new story of our 'Ocean science in action' series: oceandecade.org/tag/ocean-science-i...
