The term ecosystem health has been employed to embrace some suite of environmental goals deemed desirable. Ecosystem integrity implies a condition of an ecosystem exposed to a minimum of human influence. Ecohealth is the relationship of human health to the environment, including the effect of climate change, wars, food production, urbanization, and ecosystem structure and function. From this perspective ecosystem health is as much about sustaining human communities, economic opportunity, and human and animal health, as it is about sustaining the biological functions of ecosystems.
