[Is environmental health the future of public health?]

In France, the field of public health and public health training have developed over recent decades in parallel to the emergence of environmental health; however, these two fields are grounded in conceptual and methodological underpinnings that often differ. The authors of this article try to analyse the differences between these two approaches which both have prevention as their main purpose. Both approaches use epidemiology as a tool, but they are distinguished by their uniquely different definitions of environment. Unifying both approaches around a common basis is possible, but in order to do this, public health must evolve to expand and integrate new disciplines other than epidemiology. Supported by its close ties to societal issues of concern and recent scientific developments, the environmental health boom can and should revive public health values and contribute to the development of public health training in France.
