Jenny, your introductory quote raised a very good question for me. You are completely right. Man does have some use for nature. Otherwise, he wouldn't create such spectacular places in nature to be able to enjoy. What bothersd me is that it seems to become less useful to man (nature) because man seems to be creating more and more products out of that nature in order to satisfy some selfish need. I don't know, maybe I'm getting a little upset over it but I cant help it.
