Stratospheric ozone depletion, uv radiation and health it has been recognized for several decades that the release of chlorofluorocarbons and other atmospheric pollutants depletes stratospheric ozone, which in turn increases human exposure to ultraviolet radiation, causing skin cancer and cataracts. Ozone depletion atmospheric ozone layer depletion is a serious problem currently facing the world the ozone layer protects humans, animals, and plants from harmful ultraviolet rays money and time are being spent on ozone repair, but the problem still exists.
