Freshwater resources underlie all agricultural and industrial processes and are fundamental to our survival. No technological substitutes for fresh water exist. United States society faces acute and chronic water resource crises, analogous to those that have repeatedly contributed to the demise and reduced standards in previous cultures.

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfängen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen für die historische wie auch die disziplingeschichtliche Forschung zur Verfügung, die jeweils im historischen Kontext betrachtet werden müssen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.
