Man prioritizes material items over nature, development and expansion for the sake of development: There may be some among the readers of this book, like the earnest engineer, who believe without question that any and all forms of construction and development are intrinsic goods, in the national parks as well as anywhere else, who virtually identify quantity with quality and therefore assume that the greater the quantity of traffic, the higher the value received.
