Buffalo is an excellent example. (I tasted some for the first time this past summer, and loved it. Bison: The Other Red Meat!)
When buffalo freely roamed the plains, they were hunted almost to extinction. It was touch-and-go for awhile. We very nearly lost the species.
Nowadays, people are raising buffalo, and the population is on the rise. Someday, I expect that there will be more buffalo than there ever were before. The more we eat, the more there will be.
The entire difference is attributable to the fact that nobody owned the buffalo of the plains, while the buffalo of today are almost all private property. Until the fish of the sea can--somehow--become the private property of profit-driven individuals, they are at risk of severe depletion or extinction. The limitless rapacity of the human animal that now threatens them is exactly what will save them, but only if ownership can be established.
You may not like my suggested method of establishing ownership. That's fair. Perhaps it is unworkable. Perhaps there's a better method. But I still maintain that private ownership must be established somehow before capitalism can rescue the fisheries.
perhaps. I'm not sure of the "final solution", but I do know it must be industry led, not pushed by enviro-extremists, or junk science. Government subsidies probably should be gradually removed.
Perhaps there is a model in auctioning licences as we do for broadcast airwaves. Only that system now is also fraught with corruption.
Industry first...delay as long as possible so that industry may shake itself out. There is no real threat of extinction, at this point.
