Ozone; Protecting Earth from Ultraviolet Radiation
An introduction to ultraviolet radiation and its
increased threat due to the shrinking ozone layer examines
current controversies that alternately claim that the earth is
facing a crisis and the media is overplaying the danger.

Essay by Michael E. Kowalok.
Stratospheric Ozone Depletion
Unlike the issue of acid rain, which has long been associated with human activities and
documented by environmental observations, scientific concern about human-induced
destruction of the ozone layer dates only to about 1970. Ozone is a molecule of oxygen
(O3) that absorbs certain wavelengths of biologically damaging ultraviolet light. It is
the only gas in the atmosphere that does so and, therefore, is an essential part of the
Earth's ecological balance. The evolution of land life is believed to be tied closely to
the formation of the protective ozone layer...
