Ocean phytoplankton may be tiny, but their impact on the planet is enormous.

These microscopic organisms form the foundation of marine food chains and play a vital role in carbon sequestration and climate regulation.

At the UN Ocean Conference taking place on the French Riviera, UN News’s Fabrice Robinet spoke to Alexandra Worden, a Boston native and plankton specialist at the world-renowned Marine Biological Laboratory in Woods Hole, Massachusetts, who is working at the intersection of science, technology, and policy to better understand how nature-based solutions can support climate action.
