A.  In 1992, the devastating collapse of the cod stocks off the east coast of Newfoundland forced the Canadian government to take drastic measures and close the fishery. Over 40,000 people lost their jobs, communities are still struggling to recover and the marine ecosystem is still in a state of collapse. The disintegration of this vital fishery sounded a warning bell to governments around the world who were shocked that a relatively-sophisticated, scientifically-based fisheries management program, not unlike their own, could have gone so wrong. The Canadian government ignored warnings that their fleets were employing destructive fishing practices and refused to significantly reduce quotas citing the loss of jobs as too great a concern.
B.  In the 1950s Canadian and US east coast waters provided an annual 100,000 tons in cod catches rising to 800,000 by 1970. This over fishing led to a catch of only 300,000 tons by 1975. Canada and the US reacted by passing legislation to extend their national jurisdictions over marine-living resources out to 200 nautical miles and catches naturally declined to 139,000 tons in 1980. However the Canadian fishing industry took over and restarted the over fishing and catches rose again until, from 1985, it was the Canadians who were landing more than 250,000 tons of northern cod annually. This exploitation ravaged the stocks and by 1990 the catch was so low (29,000 tons) that in 1992 (121/2000 tons) Canada had to ban all fishing in east coast waters. In a fishery that had for over a century yielded a quarter-million ton catches, there remained a biomass of less than 1700 tons and the Fisheries Department also predicted that, even with an immediate recovery, stocks need at least 15 years before they would be healthy enough to withstand previous levels of fishing.
C.  The devastating fishing came from massive investment poured into constructing huge "draggers". Draggers haul enormous nets held open by a combination of huge steel plates and heavy chains and rollers that plough the ocean bottom. They drag up anything in the way, inflicting immense damage, destroying critical habitat and contributing to the destabilization of the northern cod ecosystem. The draggers targeted huge aggregations of cod while they were spawning, a time when the fish population is highly vulnerable to capture. Excessive trawling on spawning stocks became highly disruptive to the spawning process, and ecosystem.  In addition, the trawling activity resulted in a physical dispersion of eggs leading to a higher fertilization failure. Physical and chemical damage to larvae caused by the trawling action also reduced their chances of survival. These draggers are now banned forever from Canadian waters.
D.  Canadian media often cite excessive fishing by overseas fleets, primarily driven by the Capitalist ethic, as the primary cause of the fishing out of the north Atlantic cod stocks. Many nations took fish off the coast of Newfoundland and all used deep-sea trawlers, and many often blatantly exceeded established catch quotas and treaty agreements. There can be little doubt that non-North-American-fishing was a contributing factor in the cod stock collapse, and that the capitalist dynamics that were at work in Canada were all too similar for the foreign vessels and companies. But all of the blame cannot be put there, no matter how easy it is to do, as it does not account for the management of the resources.
E.  Who was to blame? As the exploitation of the Newfoundland fishery was so predominantly guided by the government, we can argue that a fishery is not a private area, as the fisher lacks management fights normally associated with property and common property. The state had appropriated the property, and made all of the management decisions. Fishermen get told who can fish, what they can fish, and essentially, what to do with the fish once it is caught. In this regard then, when a resource such as the Newfoundland fishery collapses, it is more a tragedy of government negligence than a tragedy of the general public.
F.  Following the 1992’s ban on northern cod fishing and most other species, an estimated 30,000 people that had already lost their jobs after the 1992 Northern Cod Moratorium took effect, were joined by an additional 12,000 fishermen and plant workers. With more than forty thousand people out of jobs, Newfoundland became an economic disaster area, as processing plants shut down, and vessels from the smallest dory to the monster draggers were made idle or sold overseas at bargain prices. Several hundred Newfoundland communities were devastated.
G.  Europeans need only look across the North Atlantic to see what could be in store for their cod fishery. In Canada they were too busy with making plans, setting expansive goals, and then allocating fish, and lots of it, instead of making sound business plans to match fishing with the limited availability of the resource. Cod populations in European waters are now so depleted that scientists have recently warned that "all fisheries in this area that target cod should be closed." The Canadian calamity demonstrates that we now have the technological capability o find and annihilate every commercial fish stock, in any ocean and do irreparable damage to entire ecosystems in the process. In Canada’s case, a two billion dollar recovery bill may only be a part of the total long-term costs. The costs to individuals and desperate communities now deprived of meaningful and sustainable employment is staggering.
选项 A、The mass unemployment.
B、The collapse of marine ecosystem.
C、The cod collapse.
D、The fleets’ destructive fishing practices.
答案C
解析 首段首句明确指出是the devastating collapse of the cod stocks 引起了纽芬兰渔场的灾难，[C]是原文的细节再现，故为答案。其他三个选项是cod disaster 引起的后果。
