There is no point in the ozone layer where there is absolutely no ozone. The concentration of ozone in the layer is never very high anyway (a few ppm) but has dropped about 4-5% overall. The concentration in the "ozone hole" over Antarctica is down at some points almost 70%.

Yes, there is a "hole" in the stratosphere (ozone layer) over Antarctica. The depletion of ozone has primarily been caused by release of CFCs (chlorfluorocarbons) from refrigerants. These emissions were severely curtailed in the mid-80s by the Montreal Protocol, but the hole is stilll there. Scientists have found DNA damage in phytoplankton, tiny algae living under the Antarctic sea ice, which is very similar to that found in skin cancer. This is because the thinning ozone layer cannot protect against incoming ultraviolet rays as well as it usually does. By the way, the thinning of the ozone layer has nothing to do with global warming.

yes of course .the ozone is depleting due to the greenhouse effect and the increased intensity of CFC's which r realeased from the refrigerators and jet planes. this is the cause skin cancers and many more skin diseases

I think you mean a hole?
Yes over the south pole,lack of sunlight to create ozone
and the volcanic activity there have created a hole of course
there aren't many people to get sunburned in Antarctica.

Yes over Antarctica and contrary to what they're still teaching in schools, it's decreasing in size.
