www.sciencemag.org SCIENCE VOL 316 1 JUNE 2007 1281 the year 2018. However, such a meaningless projection does not incorporate a large num- ber of complex factors, such as the differing life histories of species, impacts of variable ocean conditions on recruitment, and the increasing effectiveness of management measures, all significant shortcomings of the prediction method and data of Worm et al. To address persistent overfishing issues, in December 2006 the U.S. Congress passed and the National Marine Fisheries Service is now implementing provisions of the Magnuson Stevens Fishery Conservation and Manage- ment Act Reauthorization Act (MSRA). The law mandates that overfishing be eliminated for all federally managed species by 2010 and that science-based annual catch limits will be calculated for all of the 532 stocks currently under regulation.

(“Impacts of biodiversity loss on ocean ecosystem services,” 3 Nov. 2006, p. 787) that all of the world’s wild fish will be col- lapsed by 2048 attracted international media attention. Such a projection is fallacious and inappropriate to appear in a scientific jour- nal. The use of catch data to indicate stock status is misleading for several reasons.

THE RESEARCH ARTICLE “IMPACTS OF BIODIVERSITY LOSS ON OCEAN ECOSYSTEM SERVICES” BY B. Worm et al. (3 Nov. 2006, p. 787) projects that 100% of seafood-producing species stocks will collapse by 2048. The projection is inaccurate and overly pessimistic.
