Term "Sustainability"
The term sustainability was first used in the 18th century by the forestry engineer, Hans Carl von Carlowitz, and referred at the time to the fact that, in order to protect the economic basis of the forest, only as much wood should be removed as would grow back.
The modern definition and understanding of sustainability are based on the Brundtland Report (1987): “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
What the United Nations (UN) means by sustainability today is described in the 17 SDGs (Sustainable Development Goals) of there 2030 Agenda. These SDGs are worth reading and provide arguments for sustainablility, because they not only name the goals, but also explain why they are important.
