Troll, sage words of advice and an interesting question...thanks for muddling through all the hot air to contribute constructively.

Peg, you went to the trouble to post, I wish, if nothing else you, would have told me if consumption or pollution is the greatest concern, its a point which intrigues me. But I also realize that my penchant for cutting and pasting has caused a quick growth in this thread. Perhaps we can share our views at some other time when you are not quite so upset with me, the size of the thread, and hot air in general.
