Air Contamination•  Climate has an affect on the quality of our air. • Studies have shown that an increase in hot days, increases the level

of ozone in our region.• The three main air pollutants that cause health problems in the bay

area are:  1.  Ozone- Also known as "smog" common in our daily air. – Particular Matter-Tiny particles released into the air, that penetrate

deep into our lungs. – Toxic Air Contaminants- cause serious health issues even in low

concentration. •  These factors can affect the people, through our health and by

affecting the geography and economy. By increasing health issues, it requires more money for medical attention, leading to more poverty.
