Comment on "Impacts of Biodiversity Loss on Ocean Ecosystem Services"

John Jaenike

Worm et al. (Research Articles, 3 November 2006, p. 787) used a power relation to predict a global collapse of fisheries by the year 2048. However, a linear regression of the data for the past 40 years yields an excellent fit, with a predicted date of collapse of 2114. Thus, long-term projections of fisheries collapse are highly dependent on the specific statistical model used.
