'"We now have the skills and expertise to be able to restore vital marine habitats such as oyster reefs, mangrove swamps and salt marshes - which keep our seas clean, our coasts protected and provide food to support entire ecosystems," said co-author Prof Callum Roberts from the University of York, UK.
"Science gives us reason to be optimistic about the future of our oceans, but we are not currently doing enough in the UK or globally," he added.
A big challenge is climate change, which is raising sea levels and making the waters more acidic. The amount of warming that has already taken place will likely make rebuilding tropical reefs quite difficult.
"If we don't tackle climate change and raise the ambition and immediacy of these efforts, we risk wasting our efforts," said Prof Duarte.
"We also need to move closer toward reducing pressure on fish stocks, and tackle elements of pollution, such as plastic litter,"
Another big question is money. The new study estimates that it will costs $10-20bn a year to rebuild marine life by 2050. But the review also points out that for every dollar invested, the expected return would be $10.'
