Driving through Great Britain some years ago we made a loop through Scotland to the west cost then north and as we drove south I commented on how there were no trees in that part of the country - nothing but hills, hills, grassy hills and some scrub. Then I topped one hill and saw a wall of big old growth trees, in a straight line, evidently the border of some protected area (royal forest?) which was obviously the natural state - all else was deforestation.
I read a book once about wrought iron. It was astounding how much forest was required to make charcoal to support the wrought iron industry, apparently responsible for much deforestation in the US.
