Trawling of the ocean floor by fishing fleets releases roughly the same amount of carbon emissions into the water as aviation puts into the atmosphere each year, researchers said on Wednesday, calling for greater protection of the planet’s seas.
In a study published in the journal Nature, a team of 26 scientists and conservationists said marine protected areas (MPAs) are an effective tool for restoring biodiversity, expanding seafood supplies and storing climate-heating carbon.
But at present, only 7% of the ocean has been designated or proposed as an MPA, with less than 3% under full or high protection from fishing, mining and other habitat destruction.
