Interesting subject.
I always wondered why we couldn't just add a bit of ozone to all of the aerosol cans and Freon. That would fix it, right?
Really, though, there is a hole up there. The hole is actually changing rapidly right now.
In the past year, the hole has split. Now, instead of being a large hole over the South Pole, it is two smaller holes over the South Pole.
The area covered by both the holes combined is less than the single hole of a year ago.
Some scientists say this is great news, and shows that the atmosphere is improving.
Others, sensing a threat to their job security, say that this change is insignificant, even though it is the most significant happening in relation to the ozone hole in many years.
Still, as far as I know, one can find many scientists that say the ozone hole is a man-made, destructive creation, and you can find just as many who state that it is a naturally occurring event with little influence from humans.
It's definitely interesting.
