Well said Papa Bear. I think it is ironic that when we look at the geologic record we see that mother nature can be one hell of a suicidal bitch. I am concerned about pollution today, but the planet has unleashed far more destructive forces against itself than everything humans has thrown at it combined. As Conrad pointed out, the planet evolves through cycles.
By the way Conrad, I searched for the message in your post rather than angles to attack the individual behind those ideas should I have found myself in disagreement with what was stated; I was taught that is how intelligent debate flows best. Plenty of great minds throughout the ages have suffered problems of one sort or another-poor grammar, horrendous spelling, arithmetic errors, lack of strong coffee in the morning to get them firing on all cylinders, etc.-yet still offered some great ideas that advanced mankind. This is an internet forum, not a formal peer review, so I am willing to overlook certain mistakes in favor of hearing opinions.
BTW PB, what's the no fire in Cali thing you mentioned?
