Lois Gibbs 
In 1978, Lois Gibbs’s picture-perfect suburban life in Love Canal, New York turned into a nightmare when she realized that her neighborhood was built on top of a toxic dump, making residents sick and causing birth defects. Outraged, Gibbs organized a community effort against local, state and federal governments, leading to the evacuation of Love Canal and the creation of the EPA’s Superfund program, which locates and cleans up toxic sites around the nation. Gibbs later founded the Center for Health, Environment and Justice and wrote several books about the effects of toxic waste.
