Oceans can recover by 2050 if supported, study shows

This article originally featured in The Skylark’s newsletter and was written as a condensed news in brief.

It is clear that the world’s oceans are incredibly resilient, especially when it comes to human activity. From oil spills to over fishing, from hunting to plastic pollution, the seas are now also experiencing acidification and rising temperatures. A new study published in Nature has further highlighted the resilience of the oceans and states that, with a significant increase in effort, they could bounce back in thirty years.

Efforts include conservation, protecting specific species, more sustainable fishing and restoring habitats. Such activity needs to take place in nine key components of the ocean ecosystem; salt marshes, mangroves, seagrasses, coral reefs, kelp, oyster reefs, fisheries, megafauna and the deep ocean.

Co-author of the report, Prof Callum Roberts from the University of York, highlights the small window of opportunity and increased investment needed. It is estimated that is will cost between £10-20 billion per year to rebuild marine life by 2050, although a return on investment could be ten times that spent.
