In addition to being toxic for humans, tuna, swordfish, and many other fish are caught in ways that are devastating ocean habitats and fisheries. Longline fishing, the destructive fishing method often used to catch tuna and swordfish, kills thousands of endangered sea turtles per year. Our organization supports responsible and sustainable fishing.

Many of the fish species listed in the calculator are overfished, endangered, or being caught using unsustainable fishing methods. If you would like more information about sustainable seafood, please check out:
