It seems to me that some of you think that global warming and the issue with the ozone layer are the same thing...

They are infact 2 totally separate issues generaly unrelated. By that i mean both are possibly affected by humans.

Global warming is a build up of "greenhouse gasses" in the atmosphere locking in more heat like glass does and melting the icecaps resulting in higher seas.
Affected by industry, volcanoes, algae colonies, etc

The ozone layer is also being damaged (by chemicals??) which allows more ultra violet rays through than normal, this is causing the increased skin cancer.

I personally believe that global waming is a natural thing which occurs every so often.
Im not too sure about the issue with the ozone layer but im siding on the side that this IS humans fault..
