Earth A.D is film documentarian Michael Nirenberg's sweeping oral history of two American Superfund sites. Comprised of hundreds of interviews with political, environmental, corporate leaders as well as the citizens affected by living in these toxic zones, Nirenberg compares and contrasts the story behind the Tar Creek lead mine wasteland in rural Oklahoma with the 150-year history of chemical poisoning of Newtown Creek in Brooklyn, NY. The sagas of Tar Creek and Newtown show how wealth, racism, and the rural-urban divide influences how environmental disasters are viewed.
