EcoHealth is an emerging field of study researching how changes in the earth’s ecosystems affect human health. It has many prospects. EcoHealth examines changes in the biological, physical, social and economic environments and relates these changes to human health.  EcoHealth is bringing together physicians, veterinarians, ecologists, economists, social scientists, planners and others to study and understand how ecosystem changes affect human health. EcoHealth strives to provide innovative, practical solutions to reduce or reverse the negative health effects of ecosystem change.
