We never really learn........
First, a thankyou to Ed for starting this thread. A few comments.
I think the only constant we humans can be sure of is the arrogance of man... It seems the universe should revolve around us ultimatly superior humans and our omnipotant minds....:D I agree with Ed out of principle because I'm willing to admit that I have no real clue about how much we affect the environment around us in the macro sense. I can say that there are many wonders in the world that should be protected or used judiciously. Wood that is not readily renewable should be carefully managed. (Old growth and tropical rainforests). I hate to see wanton clearing of these rescorces for fast profits. I have worked as a sawyer/logger and am not at all apposed to a reasonable harvest.
I wonder about things like why we call Greenland, Greenland. And why there are 1940's airplanes 100 ft. below the ice there.
I think about beliefs held a centry or 2 ago and wonder how they could be so stupid back then. I think we are just a little less ignorant today. Maybe we are just a little more sophisticated in our ignorance today.
What would the world look like if we took greedy profit out of business and held the human person as infinitly valuable.
I think we have a long way to go to get out of barbarism and depravity. And no, I am not a globalist economicly, but maybe I should be.
Regards to all. Paul. Trying to live in the Christian tradition.
