Air Pollution Victim

Photo: Chinese man with neck lesions
A Hebei, China, resident says his neck lesions are the result of a toxic environment. It's a likely story—barely a third of China's cities have air that meets national air-quality levels, which are below World Health Organization levels. Indoor air pollution from coal burning takes more than 700,000 lives a year, and respiratory diseases cause nearly a quarter of all deaths in the countryside.
