Debra David lives with her two sisters, Mary and Betty, in their childhood home in Dobbins Heights, a North Carolina town of fewer than 850 people. Her family has been here for generations, and at 60 years old, David doesn't plan on leaving—no matter how rough life gets in her neck of the woods.
Dobbins Heights may be small and rural, but it has become increasingly packed with polluting industries over her lifetime. Within five miles of the David home sits a CSX railroad station, a Duke Energy–Smith Energy complex, a Piedmont Natural Gas resource center, and thousands of chickens at a Perdue processing plant. On top of the unpleasant smells and loud noises emanating from the facilities (and their trucks, trains and livestock), they spew diesel exhaust, nitrogen oxides, sulfur dioxides, carbon monoxide and poultry dust into the air of this largely African-American community.
