Garrett Hardin, American ecologist, author, and academic (d. 2003)
Garrett James Hardin (April 21, 1915 – September 14, 2003) was an American ecologist. He focused his career on the issue of human overpopulation, and is best known for his exposition of the tragedy of the commons, in a 1968 paper of the same title in Science, which called attention to "the damage that innocent actions by individuals can inflict on the environment". He is also known for Hardin's First Law of Human Ecology: "We can never do merely one thing. Any intrusion into nature has numerous effects, many of which are unpredictable.": 112 He is listed by the Southern Poverty Law Center as a white nationalist, whose publications were "frank in their racism and quasi-fascist ethnonationalism".
