Development frequently is confused with growth, and that is a problem, because development is a value word, and growth is not. Growth is not something we want for itself. Rather, in some cases, we may want it as a means to an end, to a value such as prosperity or security or equity. Growth may or may not actually produce those ends. Now, sustainable .
Sustainability means the ability to last, the ability to keep going.
It means development for the long-term. In personal terms, that means a commitment to our children and our grandchildren. A commitment to the continuation of society and its evolution, its enrichment not just for a little while, but for as long as we can see into the future. Rather, it's about leaving the Earth and the society better off as a result of our having been here. Sustainability is an intrinsic human value.
