New study plots out large global network of potential MPAs; would protected 30% of oceans by 2030

They released a report outlining the network on April 4, a day before the conclusion of the second round of negotiations at the United Nations toward a landmark treaty to address the ongoing decline of marine biodiversity on the high seas.
