Theo’s form of peacemaking is revealing information about a kind of oppression that is invisible to most of us: damage to our endocrine system caused by petroleum products in our environment. She accomplished this by being one of the first scientists to bring together researchers from multiple disciplines to examine each other’s work and collectively realize the damage done on humans and many other species by petroleum products. Theo and her team became an ongoing detective force revealing current scientific research on the harmful effects of specific petroleum products in our daily lives, and also harms of the “fracking” process by which the products are extracted from the earth. One of Theo’s specific goals was informing the world about the impact of these products on the human fetus. Her tools for informing the world of her findings included publications, films, public speaking, and a brilliant interactive website.
