is there a hole in the o-zone, is the hole closing up?
i will tell you, it has a lot to do with patents!
it's a Dupont thing!
the latest "theory i've read is that the whole in the ozone has always been there and is not man made. who the heck knows anymore, to many theories and no conclusive evidence, so in the meantime i'll just follow the rules set for me by the government.
