The high seas support our planet in countless ways, from regulating the climate, to feeding millions of people, to supporting industries that contribute billions of dollars to the global economy (3). Even so, less than 1% of the high seas are fully protected (4), and the current patchwork of management and lack of oversight leaves them vulnerable to abuse. In 2017, the United Nations resolved to develop an international treaty for the conservation and sustainable use of the high seas. Negotiations are set to end this year. We must ensure that the forthcoming framework conserves high-seas biodiversity and promotes sustainable and equitable use.enHigh seasEarth’s surfaceClimateGlobal economyHigh-seas biodiversityArticle
