Government reports published in the 1980s revealed that three out of four hazardous waste sites in the United States were located in African American communities. In November 1988 community activists led the first “Great Louisiana Toxic March” and Sam Kittner’s photography helped draw attention to the harmful environmental conditions encountered by African Americans living in Louisiana’s “Cancer Alley.” This area is still home to 150 oil refineries and petrochemical plants along an 80-mile industrial corridor.
