Ozone depletion occurs when the natural balance between the production and destruction of stratospheric ozone is tipped in favour of destruction. ... Although natural phenomena can cause temporary ozone loss, chlorine and bromine released from man-made compounds such as CFCs are now accepted as the main cause of...

It is now accepted that chlorine and bromine compounds in the atmosphere cause the ozone depletion observed in the `ozone hole' over Antarctica and over the North Pole. However, the relative importance of chlorine and bromine for ozone destruction in different regions of the atmosphere has not yet been clearly explained.

Ozone Depletion: Chemical destruction of the stratospheric ozone layer beyond natural reactions ... Depletion of this layer by ozone depleting substances (ODS) will lead to higher UVB levels, which in turn will cause increased skin cancers and cataracts and potential damage to some marine organisms, plants, and plastics.

You have probably heard people talk about a "hole" in our ozone layer. Damage to our Earth's giant protective umbrella is more severe in the South Pole, but, even there, no actual "hole" exists. And only a slight thinning occurs over the rest of the world.
