- Ok say that 0.01% of these chlorine agents reach the actual ozone.
- Now lets say its roughly 10,000,000,000 particles of chlorine (I'm
- no chemist what is the actual amount?) That is 100,000,000 particles
- that reach the ozone per eruption. Say on average there is one eruption
- every ten years (and going 1,000,000 years back) this is
- 10,000,000,000,000 particles in the ozone. While it may not get there
- all that often they have been there a lot longer and in much larger
- quantities than CFC's (which are being phased out by 1996).

- You don't have to be an aeronautical engineer to know how to fly! Use
- your common sense, Sun creates ozone. Where are the holes located, at
- the poles. Where is there no sun for 6 months, at the poles. It seems
- pretty reasonable to me.
- Everything isn't scientific, remember theoretically I can put my
- hand through a desk w/o touching it.
