Scientists have been warning for years that overfishing is degrading the health of the oceans and destroying the fish species on which much of humanity depends for jobs and food. Even so, it would be hard to frame the problem more dramatically than two recent articles in The Times detailing the disastrous environmental, economic and human consequences of often illegal industrial fishing.

Sharon LaFraniere showed how mechanized fishing fleets from the European Union and nations like China and Russia – usually with the complicity of local governments – have nearly picked clean the oceans off Senegal and other northwest African countries. This has ruined coastal economies and added to the surge of suddenly unemployed migrants who brave the high seas in wooden boats seeking a new life in Europe, where they are often not welcome.

The second article, by Elisabeth Rosenthal, focused on Europe’s insatiable appetite for fish – it is now the world’s largest consumer. Having overfished its own waters of popular species like tuna, swordfish and cod, Europe now imports 60 percent of what it consumes. Of that, up to half is contraband, fish caught and shipped in violation of government quotas and treaties.

The measured effects today should be enough for sensible people to realise the tragedy of the commons applies to fishing and obviously governments need to regulate the fishing to assure that fishing is sustainable. This is a serious problem exacerbated by scientific and economic illiteracy. The obvious scientific and economic solution is regulation. Determining the best regulation is tricky (and political and scientific and economic) but obviously regulation (and enforcement) is the answer.
