Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth`s stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone over Earth`s polar regions. The latter phenomenon is referred to as the ozone hole.....
