High Seas Alliance

Since its founding in 2011, the High Seas Alliance (HSA) with its 45+ non-governmental members and the International Union for Conservation of Nature, has been working to conserve marine biodiversity on the high seas. Covering nearly half of the world’s surface, the high seas—a true global commons—is only protected by a loose patchwork of poorly enforced rules that are ill-suited to address a growing onslaught of pressures to the water column and seabed below, including climate change, pollution, fishing, and emerging activities like deep-sea mining.
