They surfaced with second-degree burns on their hands. The water itself had become toxic. By that point, the corridor already had a name whispered by the people who lived there and a nickname that would eventually reach the national vocabulary: Cancer Alley. Stretching roughly 85 miles along the River Parishes of Louisiana, this narrow band of land holds more than 200 petrochemical plants and refineries. As of 2012, it accounted for 25 percent of all petrochemical production in the United States. Environmentalists call it a sacrifice zone -- a place where the rates of cancer caused by air pollution exceed the federal government's own limits of acceptable risk.

Photo credit RonPaul86, CC BY-SA 3.0. Cancer Alley sits at the intersection of environmental and racial injustice. The corridor follows the same Mississippi riverbank where antebellum sugar plantations once stood, and many petrochemical plants now occupy former plantation land. The discovery of enslaved people's grav...

Cancer Alley's proximity to the Gulf of Mexico makes it vulnerable to hurricanes that transform industrial infrastructure into environmental catastrophe. Hurricane Katrina in 2005 caused nearly 11 million gallons of oil to spill near New Orleans. Hurricane Har...
