Bernd Herrmann und Jörn Sieglerschmidt erläutern die gedanklichen Grundlagen der Umweltgeschichte. Sie zeigen auf, dass durch Menschen beeinflusste Ökosysteme, wie alle Entwicklungen in der Zeit, eine Geschichte haben. Ihre ausschließliche Zuordnung zu den Natur- oder Geschichtswissenschaften ist daher nicht sinnvoll – Umweltgeschichte ist nur als Synthese aus beiden zu verstehen. Konkreter Gegenstand der Umweltgeschichte ist die examine der Beziehungen zwischen Menschen und den von ihnen genutzten naturalen Ressourcen im historischen und kulturellen Wandel. Der Blick in die Geschichte der Umweltverhältnisse ist Teil einer ökologischen Grundbildung und belehrt über mögliche langzeitige Folgen umweltwirksamen Handelns.
