Perception or reality: oil spill risk on salmon

摘要

There is a tendency in the American scientific community to assume the worst when it comes to the effects of oil spills on the environment. Over the several years of research following the Exxon Valdez oil spill of March 1989 in Prince William sound, Alaska, scientists of the United States national Marine Fisheries Service and the Alaska Department of Fish and Game have reported long-term and continuing negative impacts of hte spill on pink salmon. In spite of the substantial evidence to the contrary, enither reassessment of results nor analysis of alternative explanations have been considered by either agency. The motivations behind such unyielding positions are examined and explanations suggested for the singular point of view.
