The counterfactual to fishing isn't nothing though. People need to eat. Any calorie not coming from seafood has a footprint on land. Some seafood like whitefish, small pelagics and farmed bivalves, when sustainably managed are about the most low carbon and environmentally low footprint foods you can eat, and they are also very micronutrient dense at a time 'silent hunger' is affecting at least a billion people on earth.
