All human activities linked with artificialization and management of natural resources should be set up on a hierarchical system (Figure 7). The degrees of freedom on each hierarchical level change according to the hierarchical context and wheater the direction is downwards or upwards, in line with the hierarchical theory [30, 43].

Decision making at any level depends on the stages above and below. Political decisions should be subordinate to economic, technologic, social and ecological levels. A right decision should be valid on all the levels of the universal legality.

Human economy can´t operate without ecosystem services, and thus, the financial value is infinite. Constanza *et al*. [74] present seventeen categories of ecosystem services: gas regulation, climatic regulation, disruption regulation, hydric regulation, water supply, erosion control, soil formation, nutrient cycle, waste treatment, pollination, biological control, shelter, food production, raw materials, genetic resources, recreation, and

It is amazing to notice that conventional productive agriculture only generates two of those seventeen categories: food and raw materials. What is more, the green revolution of industrial agriculture has a negative effect on the other fifteen. However, it´s important to
