3. John Ruskin in 1849 said in The Seven Lamps of Architecture:
   "God has lent us the earth for our life; it is a great entail. It belongs as much to those who are to come after us, and whose names are already written in the book of creation, as to us; and we have no right, by anything that we do or neglect, to involve them in unnecessary penalties, or deprive them of benefits which it is in power to bequeath"

7. The Wuppeerthal Institute (1998) says:

8. Spangenburg says that:
   "Sustainability as defined in Agenda 21 is a complex system of interacting targets in four dimensions: social, environmental, economic and institutional (in wider sense including preferences and habits).

13. The Labour government said in 1999:
    "Sustainable development is a very simple idea. It is about ensuring a better quality of life for everyone, now and for generations to come. To achieve this, sustainable development is concerned with achieving economic growth, in the form of higher living standards, while protecting and where possible enhancing the environment - not just for its own sake but because a damaged environment will sooner or later hold back economic growth and lower the quality of life - and making sure that these economic and environmental benefits are available to everyone, not just to a privileged few."
    
    
14. DEFRA
    "Sustainable development is about ensuring a better quality of life for everyone, now and for generations to come. It encompasses environmental, social and economic goals. It is about protecting and where possible enhancing the environment, not just for its own sake but because a damaged environment will sooner or later hold back economic development and lower the quality of life. It is about seeking to satisfy people's basic needs, such as providing warm homes and safe streets and giving people the opportunity to achieve their potential through education, information, participation and good health. And it requires a robust economy to create the wealth that allows needs to be satisfied, now and in the future".
