Two of today's most controversial science issues, human cloning and global environmental change, will be debated by Cornell University scientists and scholars in a public forum Saturday, June 21, at 1:30 p.m. in 105 Space Sciences Building.

A part of the Annual Josephine L. Hopkins Foundation Workshop for science journalists, the debates are open to the general public at no charge. The overall theme of the twin debates is: "Is Science Dangerous to Society? Or Is Society Dangerous to Science? Policy and Ethical Perspectives."

The first debate, "Animal and Human Cloning and Genetics," will include Peter Bruns, professor of genetics and director of the Division of Biological Sciences at Cornell; Larry Palmer, professor of law; Robert Foote, the Jacob Gould Schurman Professor of Animal Science Emeritus; and Stephen Hilgartner, assistant professor of science and technology studies.

The second debate, "Global Environmental Changes," is expected to conclude by 4:45 p.m. and features Bruce Lewenstein, associate professor of communication; Will Provine, the Charles A. Alexander Professor of Biological Sciences; Kurt Gottfried, professor of physics; and Richard Schuler, professor of economics and of civil and environmental engineering and director of the Cornell Institute for Public Affairs.

The Hopkins Foundation Workshop, which begins June 19, brings to the Cornell campus more than four dozen print and broadcast journalists for science briefings on topics such as extraterrestrial life, genetic engineering of food, citizen science and virtual reality.
