Lois Gibbs, or Lois Marie Gibbs, (born 1952) is an environmental activist whose involvement in environmental causes began in 1978, when she discovered that her 7-year-old son's elementary school in Niagara Falls, New York was built on a toxic waste dump. Subsequent investigation revealed that her "entire neighborhood" had been built on top of that same dump, the Love Canal. Wikipedia
