The study uncovers the drama of Stei Baita (Romania), a former uranium mine, which experienced during the communism period, an intensive industrialization. This shaped the territorial pattern, cultural, economic and social relationships, with a tremendous impact on the quality of the environment which was sacrificed against a rapid of a so-called economic growth. Stei Baita is a classic example of legacy mine land and the authors aim is to capture and assess all important aspects of sustainable development within this study-case (...) of disadvantaged community living in a radon prone area. More specifically, authors introduce their responses to several questions: (1) What do we know about social, economic and environmental capital of the selected settlement?; (2) Is the legacy of a uranium mine the platform of debate for negotiating for sustainable development?; and (3) What is the role of ethics in the current context of Stei Baita? Within the framework of analysis, equity, seen as part of ethics, is valued both as the premise of the debate and mandatory requirement for human development that should target sustainability. Authors have not discussed truths, but positions on identified problems by investigating community members’ perceptions. Thus, peculiarities of this community are dealt within a thematic context (e.g., resources and environment, individual development, social system). Finally, ethics is valued as social construct built by negotiating interpretations of morally desirable situations and behaviors accepted in a particular society at a certain historical moment. This view is consistent with ethical relativism which denies the existence of a unique moral truth and which sets the understanding of Stei Baita context on the path of the “new ethics”. The “new ethics” depicts the world in nuances, allowing society to surpass obstacles to the progress of understanding. (shrink)
