It has long been clear that the world’s oceans are in trouble, its coastal waters increasingly polluted and its fish stocks in various stages of decline (下降). Now comes the most shocking news in years: a report from two Canadian scientists says that the world’s mechanized fishing fleets(渔船) have managed in an only 50 years to catch nine-tenth of the world’s biggest and most economically important species(种) of fish, including cod, halibut, tuna and swordfish.

　 The report, published in the journal Nature, is the first to present a global picture of the great decline that earlier studies had done on a regional basis. It provides further fact that fishing fleets have been able to sustain(持续) harvests at high levels only by venturing further and further out to sea in a finally self-defeating effort to stay in business.

　 The crisis described in the Nature article obviously requires global solutions(方法). One is to shrink the industry. It will take political courage and money to fashion a soft landing for displaced fishermen. But there are clearly too many boats catching too few fish. Another important step is to expand America’s network of protected zones that give fish a chance to reproduce. Daniel Pauly, a Canadian scientist, argues that fully 20 percent of the world’s oceans should be set aside for this purpose.

　 Third, America must reorganize the way it manages its oceans and changes its oceans policy. Forest policy changed when the country realized that the national forests were not an inexhaustible(不枯竭的) resource and indeed belonged to all Americans, not just the loggers. A similar shift in attitude will now be required to rescue the seas.
