Isn't that everything tho?
The Tragedy of the Commons.
Once upon a time, in the days of wooden boats without fish-finders, and Loran you had to be dedicated. Maintaining a wood boat, keeping tabs on the schools, knowing how to plot a course and navigate your way back, all required a significant amount of time and effort. Today, anybody can trailer a Grady to Montauk, get a report from wherever to start, drop it in, plug the waypoint into the GPS, buzz out there, catch stuff, and buzz back, and the next day be out on a jet-ski or racing dirtbikes.
Industrialization and scientific advances have brought us many great things. It has made a lifestyle accessible to the common man that was once the purview of the wealthy, or the focused, passionate and dedicated. Unfortunately it has also brought the masses to the things that used to require a lot more investment.
Since there's no way to manufacture fish to keep up with demand, it creates a supply issue. And as long as business interests have more influence over regulators than science, I have to agree, there will be very little left.
BUT! The bright spot on the horizon is, that same technology is robbing the future generations of the will to go outdoors and brave the wilderness to catch a fish. They'd rather play iFish. Witness Bombardier divesting itself of their powersports brands. Changing world.
So eventually things may stabilize again. It will be interesting to see if I live long enough for it all to play out.
