A recent study reveals that the practice of trawling, a destructive fishing technique, the ocean floor for shrimp, cod, and other seafood results in the release of up to 370 million metric tons of CO2 into the atmosphere annually.
The study, published on Thursday in the journal Frontiers in Marine Science, scientists and environmentalists have vehemently opposed trawling for sea animals dragged out in nets.
The disturbance caused by bottom trawling to the CO2 stored in seabed sediments leads to the release of approximately 370 million metric tons of greenhouse gas into the atmosphere annually.
This amount surpasses more than double the CO2 emissions produced by the global fishing industry‘s use of fossil fuels.
Trisha Atwood, the study’s lead author and an associate professor of watershed sciences at Utah State University, “These are enclosed areas, particularly like the Mediterranean, where we can see that CO2 can create localized acidification that could be quite substantial.”
“It only takes about nine years for it to make it completely out of the ocean and into the atmosphere, and there’s enough CO2 that is being emitted by global trawling each year that people need to pay attention to it,” Atwood added.
