Human ecosystem
Human ecosystems are human-dominated ecosystems of the anthropocene era that are viewed as complex cybernetic systems by conceptual models that are increasingly used by ecological anthropologists and other scholars to examine the ecological aspects of human communities in a way that integrates multiple factors as economics, sociopolitical organization, psychological factors, and physical factors related to the environment. A human ecosystem has three central organizing concepts: human environed unit (an individual or group of individuals), environment, interactions and transactions between and within the components. The total environment includes three conceptually distinct, but interrelated environments: the natural, human constructed, and human behavioral. These environments furnish the resources and conditions necessary for life and constitute a life-support system.
