Equitable ocean governance is critical, as the oceans are essential to the planetary system and global health.oceans cover 71% of Earth’s surface and are crucial to our planet’s life-support system. Coastal and marineecosystems extend up to 100 kilometres inland, encompass the continental shelf, and include ocean systemswith depths of up to 50 metres. the distinct marine ecosystems found in these environments include estu-arine and coastal wetlands, such as marshes and mangroves, as well as sand beaches and dunes, seagrassbeds and coral and oyster reefs. they are also a source of livelihood for a significant portion of the popu-lation (Barbier, 2017) and have hitherto unexplored public health implications.
