There was a time in the last century when we, quite foolishly, believed incineration to be a superior means of waste disposal than landfills. And, for decades, many of America's most disadvantaged have been paying for those decisions with with their lifespans. South Baltimore's Curtis Bay neighborhood, for example, is home to two medical waste incinerators and an open-air coal mine. It's ranked in the 95th percentile for hazardous waste and boasts among the highest rates of asthma and lung disease in the entire country. 

The city's largest trash incinerator is the Wheelabrator–BRESCO, which burns through 2,250 tons of garbage a day. It has been in operation since the 1970s, belching out everything from mercury and lead to hydrochloric acid, sulfur dioxide, and chromium into the six surrounding working-class neighborhoods and the people who live there. In 2011, students from Benjamin Franklin High School began to push back against the construction of a new incinerator, setting off a decade-long struggle that pitted high school and college students against the power of City Hall.
