Ancient, virgin forests should be preserved, in my opinion - it doesn't matter where they are. The Hartwick Pines area near Grayling has some virgin trees in it, and they are very impressive. The number of trees, and the acres of forest in Michigan are higher now than they were 100 years ago, believe it or not. Towards the end of the nineteenth century, Michigan was scalped - almost nothing was spared. Forest management was not on anyone's mind at the time. Since then, millions of trees have been planted to replace those trees. Those huge trees were used to build parts of Detroit and Chicago. Anyone that works in older buildings will commonly see slabs of wood over 20 inches wide. Try to find a board that wide in Home Depot!
There is absolutely no reason to cut down any ancient trees for wood. Other fast-growing trees are readily available for that purpose. They are planted just like any other crop, and eventually harvested. I once owned some poroperty near Grayling, and there were some HUGE pine trees on my land. When a storm took one down, I cut it up and counted the rings. It was over 150 years old (a youngster), and there were dozens more that were much older on my land. I always treasured those trees.
