The words “Sustainable Development” are frequently used by very lightly, to the extent that they have lost their meaning. There is a presumption that for any perspective analysis or any development proposal, these two words are the most appropriate. Sustainability has been incorporated in the objectives of many studies. The historical model of industrialized societies in the 19th and 20th centuries served as the central notion of what constitutes development in both the cost-effectiveness and equity perspectives. According to some analysts, this path represents the model for global prosperity. However, a number of growing parallel literatures recognize the importance of diverse development pathways in achieving an environmentally and socio-economically better world. The term sustainable development does not bring forward all aspects of development. A new term that incorporates the wellbeing of all citizens through economic development and the preservation of the environment is needed. A “Worth-living Integrated Development” could be a term that combines economic development, social development and environmental protection. A Worth-living Integrated Development may be achieved only when human societies decide to create necessary presuppositions—at the educational, research, economic, social, political, technical/technological and environmental levels—for a better world, based on the human values of peace, justice, solidarity, political, economic and social democracy and ethics, respect for nature and for the variety of cultures of all human beings.
