Op-Ed:

- Commercial fisheries are quickly losing consumer trust as seafood fraud, ecological damage from overfishing, and illegal fishing practices continue to come under the spotlight.

The best thing that can be done to mitigate ocean acidification, argues the author, is for states, lawmakers, and organizations to work together on this issue. National Geographic
