    Ozone causes respiratory problems when inhaled by humans. The ozone layer in the atmosphere blocks ultraviolet rays that are harmful for skin and in the long term can cause cancer. Ground level ozone doesn’t have this benefit while atmospheric can not me inhaled so it poses no threat.

    Also, ozone at high altitudes absorbs harmful solar radiation, thus preventing this harmful solar radiation from reaching the surface.  So, ozone at high altitudes (in the stratosphere) is “good ozone”, while ozone at low altitudes (in the troposphere, near the surface) is harmful to humans when inhaled.
