Once a hopeful dream of urban development, Love Canal became one of the most infamous environmental disasters in U.S. history. In the 1940s, the Hooker Chemical Company used the site in Niagara Falls, New York, as a dumping ground for toxic chemical waste. Decades later, homes and a school were built over the sealed landfill, unknowingly exposing residents to deadly toxins. By the late 1970s, reports of severe health issues—birth defects, cancer, and miscarriages—forced a state of emergency. The disaster led to mass evacuations, public outcry, and the creation of the Superfund program to handle hazardous waste sites across the country.
