For unnumbered centuries of human history the wilderness has given way. The priority of industry has become dogma. Are we as yet sufficiently enlightened to realize that we must now challenge that dogma, or do without our wilderness? Do we realize that industry, which has been our good servant, might make a poor master? Let no man expect that one lone government bureau is able—even tho it be willing—to thrash out this question alone.[....] Our remnants of wilderness will yield bigger values to the nation's character and health than they will to its pocketbook, and to destroy them will be to admit that the latter are the only values that interest us.  Aldo Leopold
