From the philosophical stand the paper analyzes the fashionable concept of „sustainable development“ in three contexts: economic, technological and environmental ones. From the economic point of view sustainability is related not only to the proportional consumption of natural resources but also to the conception of man-made and natural capital as well as to the integration of environmental criteria into systemic economic instruments. The structure of technology and its application determines sustainability of our civilization. The evolutionary approach to environmental problems perceives the complexity of biospheric systems in dynamic equilibrium as controvertial processes, not as a static state. Traditional beliefs in Man’s sustainability are no longer valid. Unless mankind finds more cooperative and steward-like relationship towards Nature, it may turn out to be a blind alley of Evolution in the end.
