There is no need for an end to fish, or to fishing for that matter. But there is an urgent need for governments to free themselves from the fishing-industrial complex and its Ponzi scheme, to stop subsidizing the fishing-industrial complex and awarding it fishing rights, when it should in fact pay for the privilege to fish.
In the Java Sea in Indonesia, I have seen fishers going out in the morning, six of them going out and coming back with five pounds of fish. That is the end point, a pound of fish per person per day to sell for rice. That's where fisheries go if you let it happen. That's where it stabilizes. These people cannot feed their families.
