John Michael Greer

John Michael Greer (born 1962) is an American author who writes on the environment, various religions and occult topics. He served from December 2003 to December 2015 as the Grand Archdruid of the Ancient Order of Druid in America, and since then has focused on the Druidical Order of the Golden Dawn, which he founded in 2013.
Writing in The Futurist magazine, Rick Docksai declared that Greer's book The Ecotechnic Future is "as realistic a portrayal of the end of civilization as one is likely to find." It was also positively reviewed in Choice: Current Reviews for Academic Libraries and was recommended in the industry journal Energy Policy.
The International Journal of Agricultural Sustainability referred to his book The Wealth of Nature as "challeng[ing] the paradigms that underlie the complex system of wealth distribution we know as economics."
His book The New Encyclopedia of the Occult was selected as a reference text in 2005 by American Libraries and noted by Booklist and Publishers Weekly.
