Human resource is the main beneficiary of valorizing systems, natural resources and, at the same time, the main disturbant of integrity or balance of these natural resources and ecosystems. This is a reciprocal conditioning of existence and evolution man-nature, conditioning which the author will highlight in the paper. The human resource has its own potentialities which can be put at service for development. People have the capacity to receive, process information and knowledge, to generate information and knowledge with commercial value. Human intelligence thus becomes a factor of economic-social development and a parameter of integration in world flows, as a companion to globalization phenomenon.
