Oceans can be restored to former glory within 30 years, say scientists

Major review reports recovery of marine life but a redoubling of efforts is still needed

The glory of the world's oceans could be restored within a generation, according to a major new scientific review. It reports rebounding sea life, from humpback whales off Australia to elephant seals in the US and green turtles in Japan.

Through rampant overfishing, pollution and coastal destruction, humanity has inflicted severe damage on the oceans and its inhabitants for centuries. But conservation successes, while still isolated, demonstrate the remarkable resilience of the seas.
