An ecologist and a medical epidemiologist will discuss potential ecological and human-health risks related to agricultural biotechnology Thursday, Nov. 30, at the University of California, Davis. Peter M. Kareiva of the National Oceanic and Atmospheric Administration Fisheries in Seattle, Wash., and Arthur L. Reingold of UC Berkeley's School of Public Health, will present public talks at 7:30 p.m. in the campus's Buehler Alumni and Visitors Center on Old Davis Road. Kareiva, formerly a professor at the University of Washington, will talk about "Ecological Risks and GMOs: How Science, Government and Policy Makers Fail Us." Reingold, a medical doctor and head of the Division of Public Health Biology and Epidemiology in UC Berkeley's School of Public Health, will present a lecture titled "Can Epidemiologists Detect Adverse Effects of GMOs on Human Health?" Their talks will be the third of eight events in the Biotechnology, Policy, and Society Lecture Series, held on selected Thursday evenings until early March. The biotechnology lecture series is sponsored by the campus's Center for History, Society, and Culture in an effort to present a broad range of thought on biotechnology and its social implications.
