From fishermen to fish to reefs, the theme of this year’s United Nations World Oceans Day, “Life and Livelihoods,” connects to just about every aspect of ocean health and coastal economies. After all, ocean health affects industries and flood resilience our ability to sequester carbon. But how do we secure ocean health? A global community of scientists agree that the foolproof way to support ecosystems and their services is to conserve them.
Research backs them up. A study published earlier this year in the journal Nature outlines three main benefits to protecting ocean areas: preserving biodiversity, increasing the yield of fisheries and storing marine carbon. Global coordination, as opposed to independent national action, authors say, has the potential to double the effectiveness of conservation efforts. The body of research backing up the economic benefits of marine protected areas (MPAs) is broad. One meta-analysis found a 670 percent increase in the biomass of whole fish assemblages in no-take marine reserves compared to unprotected areas outside their boundaries.
