The American concept of wilderness has been criticized by some nature writers. For example, William Cronon writes that what he calls a wilderness ethic or cult may “teach us to be dismissive or even contemptuous of such humble places and experiences”, and that “wilderness tends to privilege some parts of nature at the expense of others”, using as an example “the mighty canyon more inspiring than the humble marsh.”[25] This is most clearly visible with the fact that nearly all U.S. National Parks preserve spectacular canyons and mountains, and it was not until the 1940s that a swamp became a national park—the Everglades. In the mid-20th century national parks started to protect biodiversity, not simply attractive scenery.
