What good is science?

There appears to be a classic standoff between science and the demands of the market regarding Atlantic bluefin tuna. "Stocks are dwindling", say the scientists; "fish on" say the countries with a big economic stake in the fishery.

For anyone who lived through the collapse of the Atlantic cod, the situation and the rhetoric seem familiar.

And remember, we stopped fishing the cod in 1992. They still haven't come back.
