Living Blue Planet Report 2015: Species, Habitats and Human Well-Being

Between 1970 and 2012, populations of marine vertebrates fell by 49 percent, largely as a result of human actions, with potentially catastrophic consequences, a report from the warns. The report, (72 pages, PDF), found that the populations of some fish species were down nearly 75 percent, due in large part to human consumption. In addition, steep declines in, and global threats to, coral reefs, mangroves, and seagrasses, all of which support marine ecosystems, pose a grave risk not only to ocean health but also to the coastal communities that depend on them economically, socially, and culturally. The largest factors behind the declines are overfishing, habitat destruction, and climate change, the report notes, highlighting the need to protect critical marine habitats, manage fish stocks sustainably, improve fishing practices, and redirect funding to effective interventions.
