From Wikipedia:

Ozone depletion refers to the reduction of ozone (O3) in the Earth’s stratosphere (the “ozone layer”). CFCs and other contributory substances are referred to as ozone-depleting substances. According to Wikipedia there are two distinct but related phenomena, which have been observed since the late 1970s: (1) a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere, and (2) a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole.

Because the ozone layer prevents most harmful wavelengths of ultraviolet light from passing through the Earth’s atmosphere, the observed and projected decreases in ozone are a matter of serious concern. Wikipedia lists the following suspected biological consequences of this increased radiation:
skin cancer, cataracts, damage to plants, and reduction of plankton populations in the ocean’s photic zone.
