Love Canal: Children and Toxic Waste

The neighborhood called Love Canal in Niagara Falls, New York, was neither the first nor the worst toxic waste dump, but it became a national story in the late 1970s thanks to the organizing efforts of Lois Gibbs, who fought to protect Love Canal's children, including her own, from the 20,000 tons of toxic waste in the ground.
