In the late 1800's, most of Central PA was deforested. Either for
lumber, or for the iron industry. I was told that you could go to the
top of Tussey mountain south of my QTH, and not see a single tree in any
direction. Since the people who were making the charcoal that was used
to make the iron thought that planting new trees wasn't a cost effective
option - if they indeed thought about it at all - they eventually ran
out of fuel.

Some sea-going Pacific islanders used up all their trees
and then couldn't build any boats. :-(
