Nicholas Georgescu-Roegen was a Romanian mathematician, statistician and economist. He is best known today for his 1971 book The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity. An esteemed professor and educator in economics, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics.

Sustainable development is an approach to growth and human development that aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. The aim is to have a society where living conditions and resources meet human needs without undermining planetary integrity. Sustainable development aims to balance the needs of the economy, environment, and social well-being. The Brundtland Report in 1987 helped to make the concept of sustainable development better known.
