A former coal miner suffering from end stage black lung disease lies in a hospital bed. He is 85 years old and worked for 35 years in the mines. He's been tested 15 to 20 times for black lung and keeps being turned down by doctors who blame his illness on other health problems. Each year, an average of 24,000 Americans die as a result of pollution from coal-fired power plants, including 2,800 from lung cancer.
