The scientists say there is now the knowledge to create an ocean renaissance for wildlife by 2050 and with it bolster the services that the world’s people rely on, from food to coastal protection to climate stability. The measures needed, including protecting large swathes of ocean, sustainable fishing and pollution controls, would cost billions of dollars a year, the scientists say, but would bring benefits 10 times as high.
