Our whole life is defined by the SPACE that provides its possibilities, framework and boundaries. For SUSTAINABILITY, it is in this space that we must ensure harmony between natural, social and economic influences and agents. Today, there are environmental linkages in all of the natural sciences (and beyond!), but they are not built into a system of scientific requirements. The concept of the ENVIRONMENT is changing, legal disputes are based on the nature of environmental data, fact which consists an obstacle in the use of IT technology: exact data interpretation is the basis for the management and organisation of environmental data, for clustering, which is essential in network research - in our practical use,- environmental modelling.
