The oceans regulate the climate, absorb carbon, and serve as the cradle of the planet’s greatest biodiversity—but they face growing pressure from plastic pollution and climate change. This panel discusses public policies, legal frameworks, and preservation efforts focused on mangroves, coastal zones, and the high seas, highlighting the urgency of integrated ocean governance. Bringing together science, coastal communities, and global initiatives aligned with the UN Decade of Ocean Science, the discussion reflects on how to protect this “blue breath” that is essential to life and the planet’s future.
