Encyclopedia
Anthropogenic effects, processes or materials are those that are derived from human activities, as opposed to those occurring in natural environments without human influence.
The term is often used in the context of environmental externalities in the form of chemical or biological wastes that are produced as by-products of otherwise purposeful human activities.
The term anthropogenic designates an effect or object resulting from human activity. The term was first introduced as "anthropocene" in the mid-1970s by the atmospheric scientist Paul Crutzen. Shortly after, Sherwood Rowling and Mario Molina published a series of articles putting forward the idea of the impact of chlorofluorocarbons (CFCs) on the stratospheric ozone. The term is used in the context of pollution emissions that are produced as a result of human industry.
