Re: But as we reach the limits of the number of fish we can pull from the seas (at least for desirable types of fish, its not like we are completely denuding the seas of life), it makes sense to remove fishing (at least large scale commercial fishing, I'm not talking about someone going out with a pole and catching a couple of fish) from "the commons". If the whole of an ecosystem ('south Atlantic coastal', mid-Atlantic coastal', etc.) is managed comprehensively as one single resource... then production can be SUSTAINED at much higher average levels then when a 'land rush' approach on the public commons is the rule. For example: setting aside certain 'no-fish' areas as nurseries guarantees that more young fish will be spawned and will then migrate to the 'taking areas'. Such scientific management has worked very well in other areas, and allowed collapsed fisheries to be restored and rebound thus: more money for everyone in the long-run. Same with legally banning certain fishing practices which actually destroy the resource. In certain areas, once productive fisheries have been destroyed by drag-nets turning the bottoms into vast deserts of smooth sand... with no more nooks and crannies and reefs and such for young fish to shelter and grow. Industrial pollution, or massive amounts of effluent and agricultural run-off flowing into coastal zones can also be directly responsible for reducing or eliminating production from the resource.
