Can you please tell me about health effects of deteriorating ozone on humans with asthma?

Ozone. Ozone is a pollutant at ground level created by emissions like car and truck exhaust. Ozone is a respiratory irritant that makes asthma worse. Very high altitude atmospheric ozone (the ozone layer) acts as a filter for uv light. This has nothing to do with asthma but may increase risk of skin cancer from sun exposure due to the deterioration of that "ozone layer.".
