„In the early days our forefathers could cut down a forest or exhaust the fertility of a farm and then blithely move to a new forest or a new farm… The highest concept of statesmanship was to make it possible for the eager, aggressive pioneer to possess, to despoil and then repeat the process indefinitely. …[Shortsided and unchecked greed resulted in] denuded forests, floods, droughts, a disappearing water table, erosion, a less stable and equable climate, a vanishing wildlife.“
as quoted by Douglas H. Strong, Dreamers & Defenders: American Conservationists (1988) Ch. 7 "Harold Ickes," p.157
