I’m the founder and chief executive of The Ocean Cleanup, a non-profit organization based in Rotterdam, the Netherlands, that aims to remove plastic pollution from the oceans. My team and I do this in two main ways: by dragging nets across areas where plastic accumulates, such as the Great Pacific Garbage Patch, a collection of debris in the North Pacific Ocean; and by intercepting waste in rivers before it reaches the sea. We want to reduce ocean plastic pollution by 90% by 2040.
