A group of leading global scientists has suggested, in a new review published in Nature magazine, that there is a chance that the world’s oceans could be restored by 2050, but only if we take drastic action immediately.
One of the report’s authors, Professor Carlos Duarte of the King Abdullah University of Science and Technology in Saudi Arabia, says that, 'we know what we ought to do to rebuild marine life, and we have evidence that this goal can be achieved within three decades [...] Indeed, this requires that we accelerate our efforts, and spread them to areas where efforts are currently modest'. The report has concluded that the oceans are more resilient than we might expect, but they cannot withstand the abuse humanity is subjecting them to for much longer. Currently, at least one-third of fish stocks are over-fished, one third to half of vulnerable marine habitats have been lost, and a substantial proportion of all coastal oceans suffer from pollution, eutrophication, oxygen depletion, and ocean warming. In 2015, it was predicted that the amount of rubbish in the oceans could double by 2025. All of these factors must be rectified if the oceans are to return to their former glory.
