gnu, we've had some really great PM's recently, but I have to take exception to your comments about the woman and the possibility that in her case being burned as a witch might have been a good idea. Burning someone because of their spiritual beliefs is never a good idea. I know you probably had your tongue firmly in your cheek, but I, for one, found it offensive.

Bert, I missed your posting, but Rog and I would be very interested to know more about your friend's a/c.

If one's house was filthy wouldn't one want to clean it up and keep it that way? Ultimately that is what the Earth is, our one and only domicile. Let's get it clean and keep it that way, then see what happens to the changes we are seeing. It could be the only totally global and definitive way to prove once and for all whether we really effect the environment or not. Personally I have no doubt that we do, the same as how we effect our house's cleanliness by living in it.

And, as for you who might be desparaging us treehuggers, as The Virginian said to Trampas, "Smile when you call me that."
