Air is essential to life.
Every summer, air pollution drives thousands of Massachusetts residents indoors and into emergency rooms. In fact, more than 750,000 people in Massachusetts suffer from heart or lung ailments that are seriously aggravated by air pollution and smog. Diseases aggravated by air pollution include chronic sinusitis, bronchitis, asthma, and allergies. Studies suggest that air pollution also contributes to pulmonary problems in developing fetuses and young children, as well as damage to the immune system in adults. Elderly people lose important respiratory defense mechanisms as they age.
