Ecosystems and human well-being : health synthesis : a report of the Millenium Ecosystem Assessment

Abstract

Ecosystem services are indispensable to the well-being and health of people everywhere. In addition to providing life's basic needs, changes in their flow affect livelihoods, income, local migration and, on occasion, political conflict. The resultant impacts on economic and physical security, freedom, choice and social relations have wide-ranging impacts on well-being and health.
