The long term outcome is a heavily subsidized industry that overharvests the resource. 3.The complexity of underlying biological and physical systems precludes a reductionist approach to management. Optimum levels of exploitation must be determined by trial and error. 4.Large levels of natural variability mask the effects of overexploitation. Initial overexploitation is not detectable until it is severe and often irreversible.
Scientific consensus is unattainable.
The problem is managing humans not fish. Scientific certainty and consensus in itself cannot prevent overexploitation. Theoretical niceties are not required. Most principles of decision making under uncertainty are common sense. The lure of short term profits and the lack of a holistic, long term, and comprehensive valuation system continues to cause immense social and environmental damage.
