Ecologist Dr. Sandra Steingraber will speak on environmental issues related to health in Samuelson Chapel at California Lutheran University at 10 a.m. and 4 p.m. Mon., Nov. 6.

A scientist as well as a cancer survivor, Steingraber is internationally recognized as an expert on the ecological links to cancer and reproductive health. Her acclaimed book "Living Downstream: An Ecologist Looks at

Cancer and the Environment" presents cancer as a human rights issue.

In her morning lecture, "Contaminated Without Consent: How Pollutants in Air, Food and Water Violate Human Rights," Steingraber will discuss the ongoing revolution taking place in environmental health and the ethical and moral questions that emerge from it. "The Precautionary Principle:

Science or anti-Science?" is the subject of the afternoon lecture, during which the evolving relationship between science and precaution will be illustrated through historical stories-from rabies and cholera to antismoking laws and mercurycontaminated tuna.

Admission is free. CLU is at 60 W. Olsen Road, Thousand Oaks. For more information, call (805) 493-3233.
