Paul Krugman points us to the success story of the rebound of US fish stocks. He then makes an amazing leap to climate change saying, “Fighting climate change isn’t really all that different from saving fisheries; if we ever get around to doing the obvious, it will be easier and more successful than anyone now expects.”
I actually agree with the first part, and the Vox article that Krugman links to makes the point pretty well, just not in the way Paul wants it to be made.
Now the big caveat: Yes, US fisheries seem to be recovering. But that’s not true for much of the rest of the world. And, given that the United States imports around 91 percent of its seafood, this is a pretty crucial caveat.
All told, the best-managed fisheries around the world — the United States, Canada, Australia, New Zealand, Norway, Iceland — only make up about 16 percent of the global catch, according to a recent paper in Marine Pollution Bulletin by Tony Pitcher and William Cheung of the University of British Columbia.
By contrast, more than 80 percent of the world’s fish are caught in the rest of the world, in places like Asia and Africa — where rules are often less strict. The data here is fairly patchy, but the paper notes that many of these nations are less likely to follow the UN’s Code of Conduct for Responsible Fisheries, and there’s evidence that “serious depletions” may be occurring there:
“It all depends where you look,” Pitcher told me in an interview last year. “There are a few places where fisheries are doing better: The US, Australia, Canada, Norway. But those are relatively rare. In most places, the evidence suggests that things are getting worse.”
