Carolyn Raffensperger, Executive Director of the Science and Environmental Health Network, which, since 1998 has been the leading proponent in the U.S. of the Precautionary Principle as a basis for environmental and public health policy, was formerly an archeologist but, horrified at the destruction of the lands in which she was working, went to law school and became an activist to protect ecosystems and future generations. A co-convener of the historic 1998 Wingspread Conference on the Precautionary Principle and the Women’s Congresses for Future Generations held in 2012, 2014, and 2026, Carolyn co-edited Precautionary Tools for Reshaping Environmental Policy (2006) and Protecting Public Health and the Environment: Implementing the Precautionary Principle (1999).
