Scientists have identified proven interventions that, if scaled up, could almost completely restore ocean ecosystems within a generation.
In the past 4 decades, populations of marine creatures have suffered catastrophic declines. Data from a 2018 report by the World Wildlife Fund (WWF) show an overall decline of 60% on average for mammals, birds, fish, reptiles, and amphibians, an average drop of well over half in less than 50 years.
But a new analysis, appearing in Nature, concludes that a concerted, international effort could rebuild depleted ocean ecosystems and restore their structures, functions, and resilience by 2050. Governments, industry, private companies, and societies would need to pull together and deploy vast resources, but
