Barry Estabrook asks a great question:
There is a strong likelihood that someone in this generation will be the last human to eat a bluefin tuna. By most scientific accounts, the species hovers on the brink of extinction, if it hasn’t already crossed that line.
As they say, read the whole thing.
Probably it will be a Japanese person...the Bluefin Tuna is loved to death there.
