Air

 

Air is vital for living, but breathing polluted air may damage our health and shorten our life span. According to the American Lung Association, the number of people who die from asthma has almost doubled since 1979.

Being aware of the dangers of constant exposure to pollutants is the first step to improve our air quality. Next we must strive to reduce pollution from automobile, factory emissions, and elsewhere to help clean the air we need to live.
