The fillet of flounder sitting on your plate comes with a severe environmental cost. To catch it, a ship running on fossil fuels spewed greenhouse gases as it dragged a trawl net across the seafloor, devastating the ecosystems in its path. Obvious enough. But new research shows that the consequences extend even further: Trawl nets are hauling up both food and a huge amount of carbon that’s supposed to be sequestered in the murky depths.
In a paper publishing in the journal Frontiers in Marine Science, researchers have tallied up an estimate of how much seafloor carbon the bottom-trawling industry stirs into the water and how much of that is
