The writer needs to clarify the following reference to John Muir that was made in the article as it sounds as if Muir was a conservationist in order to protect his hunting and fishing grounds like Roosevelt and Hornaday apparently did, something which I have never heard of.
"Nineteenth-century trailblazers such as John Muir grew alarmed as they saw wildlife decimated, forests denuded and scenery despoiled. Among the loudest protesters were affluent outdoorsmen, such as Theodore Roosevelt, founder of the Boone and Crockett Club, and William Temple Hornaday, first director of the New York Zoological Society.
By calling to protect nature, these conservationists also protected their own hunting and fishing entitlements. They attacked the rural poor, immigrants and minorities, who Hornaday once called the “regular army of destruction” because they took fish and game for subsistence or sale. They used their money and power to license hunters and anglers, limit harvests and ban equipment."
Here are some sources on John Muir which describe him as a preservationist unlike many conservationists who favored the “use” of national parks, forests and so forth.
John Muir’s Defense of Wildlife
As the author appears to be saying in his article, there is a difference between being an adventurous environmentalist (or techno-weenie) who sees nature as a playground and someone who can find peace and enjoyment merely from taking a walk in the woods or in a city park by their house. Nature is all around us and it is unnecessary to consume very much to enjoy and appreciate it.
