This paper addresses the concept of sustainable development and, more particularly, its applicability in underdeveloped economies when analyzing reciprocal effects between economic organization and environmental issues. It also addresses the relationships between development and underdevelopment, from an ecological economics' approach, and its theoretical implications regarding the concept of sustainable development. We conclude that the specificities of Latin American economies, when compared to those economies of developed countries, also entail, beyond economical disparities, the existence of strong antagonisms from an environmental standpoint, which are recurrently ignored by most of the interpretations concerning sustainable development.
