The coming year will be a pivotal one for the ocean. United Nations delegates will begin negotiations to draft an international treaty to protect the biodiversity of the high seas – the 60 percent of the ocean beyond national jurisdiction Meanwhile, the International Maritime Organization is expected to issue greenhouse-gas reduction goals for shipping, a global industry not subject to the Paris climate agreement. And the movement toward sustainable aquaculture will accelerate as demand for seafood as a healthy source of protein to feed a growing world population rises, even as populations of wild fish decline. Jessica Leber, Ocean Deeply’s deputy managing editor, speaks with Peggy Kalas, director of the High Seas Alliance, Kathy Metcalf, president and chief executive of the Chamber of Shipping of America and Amy Novogratz, managing partner of the aquaculture-focused investment firm Aqua-Spark.
