Ocean ecosystems can be restored to health by 2050, researchers say; combo of MPAs & restoration key
The future for the world’s oceans often looks grim. Fisheries are set to collapse by 2048, according to one study, and 8 million tons of plastic pollute the ocean every year, causing considerable damage to delicate marine ecosystems. Yet a new study in Nature offers an alternative, and more optimistic view on the ocean’s future: it asserts that the entire marine environment could be substantially rebuilt by 2050, if humanity is able to step up to the challenge.
The key to success, the authors say, is lessening the impact and stresses on the ocean, while restoring damaged ecosystems, and trying to reduce carbon emissions that drive climate change.
