The Tragedy of the Fishy Commons

In the face of "a major scientific study" that finds

There will be virtually nothing left to fish from the seas by the middle of the century if current trends continue

we have statements like this from the National Federation of Fishermen's Organisations:

We have to be very careful about making grandiose, broad-brush predictions for 40 or 50 years and on a global scale also.

OK, let's not make any rigorous, scientifically-grounded, broad-brush predictions for 40 or 50 years and on a global scale, then: we'll just carry on depleting the stocks as if everything's fine until there's nothing left.

You see how easy it was to solve this fish stock problem thanks to the fine minds of the National Federation of Fishermen's Organisations?
