"Meeting the needs of the present without compromising the ability of future generations to meet their own needs." Brundtland Commission report (1987)
"Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment. To pursue sustainability is to create and maintain the conditions under which humans and nature can exist in productive harmony to support present and future generations."
“Sustainability is improving human well being and ensuring social equity for present and future generations while safeguarding the planet’s life-supporting ecosystems.” Chris Boone Dean, School of Sustainability
