I'm not sure I'd bet the farm quite yet.
"It means that the probability of extinction is 100% and the only question is how long it is going to take," he told BBC News.
That's one hell of a bold statement with absolutely no numbers to back it up. That's not to say that there hasn't been research to draw conclusions, but, it's a statement that can never be validated, so why make it. It's a foregone conclusion that SOMETHING will be done within 10 years. Not to mention, there's one hell of a chance that the species themselves may adapt to survive.
Another note to mention is the amount of fishing that still occurs on the westcoast of canada/usa. I have friends that either are involved in salmon sport fishing lodges, or commercial fishing. And although numbers have declined in some years, they have also seen increases in others.
I truly believe that many of the fresh seafood stocks are in decline, I won't dispute that, but, not buying that I won't be able to eat wild salmon within 10 years. I see thousands of them making it upstream to spawn within minutes from my house every fall. When it comes to protecting our resources, i am down for the cause, but the amount of unsubstantiated claims to scare the general public about the environment is becoming a little much. IMO.
