A March 12-13 conference at the University of Oregon looks at how scientists can participate in environmental politics and policy-making. "The 1994 Public Interest Science Conference" includes panels on science in the courtroom, scientists and the Endangered Species Act, and the use or misuse of science by politicians. More than two dozen panelists will speak at the conference, including Jeff DeBonis, founder of the Washington, D.C.-based Public Employees for Environmental Responsibility, and Vic Sher, a Seattle, Wash., attorney for the Sierra Club Legal Defense Fund who led the fight to save old-growth timber and protect the spotted owl. John Vandermeer, a biologist at the University of Michigan, and Wilma Subra, the president of a woman-owned analytical laboratory in Louisiana, are keynote speakers.
