Stat: 680 million—According to the United Nations, about 680 million people live in low-lying coastal zones around the world, a number expected to increase to 1 billion by 2050.  Story: In this episode, we explore how communities that rely on a healthy ocean are working to create marine protected areas (MPAs) to preserve biodiversity—and their livelihoods. In addition to hearing from Ludovic Burns Tuki, a community leader on Easter Island, home to the Rapa Nui MPA, we speak with Johnny Briggs from the Pew Bertarelli Ocean Legacy about the role of MPAs in restoring the ocean and safeguarding cultural traditions tied to the seas.
