Just something to add.
Our beloved Congress has a lot to do with the over fishing aspect of the story. Back in the seventies, we had a Congressman named Studds, not a very nice guy, who along with a Senator from, I believe, the State of Washington, decided to get the government involved in the fishing industry.
Fishing up to that time, was a family affair. If your father was a fishermen, you were one. Most of the boats were wooden and old, but the families made a living.
Studds decided that there should be more newer boats, so the government got into the business of financing new boats. To the people of New Bedford, this looked good. Congressman Studds was bringing home the Bacon. The only problem was now every Lawyer in New Bedford got into the fishing industry, because the government would help them to buy the boats. Now everybody got into the fishing industry. Hence, over fishing.
During the eighties, the government decided that we had to many fishing boats, so the government bought back the boats at a profit for the lawyers. The only problem, it was to late.
End of story.
