what can we do to stop it
what we could to do to stop overfishing is join an organisation such as the sea shepherd which are trying to stop overfishing an other marine crimes. you could also protest grab lots of big signs and a whole bunch of people and protest to companies that overfishing telling them to STOP OVERFISHING. if you really want to stop overfishing you could stop eating fish altogether i know it will not stop overfishing but it might be something you want to try.
