Nachhaltigkeit: An initial use of the term sustainability in German in the sense of a long-term responsible use of a resource is documented by Hans Carl von Carlowitz in 1713 in his work Silvicultura oeconomica. Carlowitz asked, “How to do a sothane conservation and cultivation of the wood / that there is a continuous and sustainable use / because it is an indispensable thing / without which the country may not stay in its ditch”.
