A Growing Problem
The ocean's living resources are being exploited at rates that are unprecedented and potentially irreversible. The effects of this overexploitation range from the primary impacts of extinctions and loss of biological diversity, to the secondary and tertiary effects of habitat degradation and potential economic collapse. In the face of incredible population growth and the associated growing protein needs, this trend appears unlikely to change without a serious commitment on the part of the global community.
The fate of our marine resources was publicized recently in a 2006 study that examined the sustainability of our current global fishing industry. Quite dismally, the study concluded that within 50 years, most of the important fish species will be economically extinct (Worm, 2006).

Case Study: Collapse of Canadian Cod Fisheries
|
|
For example, a case study of the collapse of the cod fishery in the Atlantic shows the complexities of management, as well as the far reaching impacts. Once the largest cod fishery in the world, the northern cod industry off the eastern coast of Canada experienced a sudden collapse in population numbers in 1993. The specific cause was likely related to the local fishery scientists overestimating the numbers of new fish being hatched and entering the population (Myers, 1997).
This failure of fishery managers and scientists to accurately estimate population sizes resulted in wide-spread social and economic disasters, ultimately costing the public billions of dollars in lost wages and social aid programs (Walters, 2004). The fishery has yet to reopen.
