Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. World Health Organization 1948


Air Pollution and Leading Causes of Death in Americans  Heart Disease – leading cause in US - 617,527 in 2008  Myocardial Infarct  Congestive Heart Failure  Fatal Arrhythmia  Malignant neoplasms – Second leading cause in US, 566,137 deaths in 2008 Source: CDC, 2011

 Respiratory disease – third leading cause in US – 141,075 in 2008  Asthma (esp. kids)  Emphysema  Bronchitis  Cancer  Stroke – Fourth leading cause in US, 133,750 deaths in 2008
