Answer 1

True
====

One way cars create pollution is by contributing to the amount of ground-level ozone (not to be confused with the atmospheric ozone layer). In the atmosphere, the ozone layer shields the planet from harmful ultraviolet radiation rays. But on the ground, ozone is another matter, causing hazy smog and respiratory problems. Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog) (30 Simple Things 11). The seriousness of ground-level ozone should not be underestimated. According to the World Resources Institute:

Ozone pollution has become widespread in cities in Europe, North America, and Japan as auto and industrial emissions have increased. ... Breathing ozone concentrations of 0.012 ppm&emdash;levels typical in many cities&emdash;can irritate the respiratory tract and impair lung function, causing coughing, shortness of breath, and chest pain ... Evidence also suggests ozone exposure lowers the body's defenses, increasing susceptibility to respiratory infections
