The Anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the Earth‘secosystems. The term was coined recently by ecologist Eugene F. Stoermer, but has been widely popularized by the Nobel Prize-winning atmospheric chemist, Paul Crutzen, who regards the influence of human behavior on the Earth’s atmosphere in recent centuries as so significant as to constitute a new geological epoch for its lithosphere. To date, the term has not been adopted as part of the official nomenclature of the geological field of study. – Wikipedia
Interesting discussion on Environmentalism and whether a slightly different approach is needed.
