There is no "hole." There is a "thinning" or depletion of the ozone layer.

This is caused by the low amount of sunlight in Anartica during its winter, since sunlight causes oxygen to ionize into ozone.

This has nothing to do with CFC's or Freon, but a lot to do with sunlight.

Got science?

You are incorrect on this subject. The "ozone hole" refers to drastically lowered ozone concentrations in the Antarctic stratosphere above the winter polar vortex, due to the reactions of chlorine with ozone that are catalytically enhanced on ice crystals in polar clouds.

If you would really like to "get science", I recommend this outstanding Web site on the subject:

The Ozone Hole Tour. Part 3, "The Science of the Ozone Hole", will be of particular interest to you.

In the news this morning was the note that American pupils rank 15th in industrialized societies for ability in the 3 Rs, Reading, Math, and Science. But we're up to date with PC and dating protocol. Looks like American pre-eminence in the world is drawing to an end; that type of social evolution is usually concluded with a sudden overruning and complete destruction of the society.

And the changes in the size are due to fluctuations of the sun, and not CFC, or SUV's.

Excellent post!!!

Factual: (There is no "hole." There is a "thinning" or depletion of the ozone layer. )

Listing the Cause: (This is caused by the low amount of sunlight in Anartica during its winter, since sunlight causes oxygen to ionize into ozone.)

I believe the thinning of the Ozone over the Antartic was first discovered in 1958 during the International Geophysical Year. The scientist who made the observation correctly theroized it was caused by the lack of sunlight which occures during a hemoshpere's winter soltice.

How much grant money has to be wasted before they finally confirm what was known in 1958, is yet to be seen.
