Scientists believe they can drive the discussion on the environmental impacts of human activity by encapsulating them with models and equations. But societies, economies and their environmental aspects are extremely complicated and unpredictable systems. It is practically impossible to calculate their evolution with deterministic models as we ignore many other stochastic parameters which are included in the capitalist economy and make the environmental science an “equivocation of a sophism”. Nevertheless we feel that the blind and catastrophic way of the devouring capitalist growth leads our natural habitat to a certain future disaster. Moreover, we know that in order to prevent environmental disasters we have to find ways to avoid their genesis. This can be approached by not choosing a way of living based in greed and overconsumption in the developed world; the first area to focus for the achievement of this goal would be the general education of people in young ages. This paper presents the basic ideas for the creation of a temporary prototype children community and the education of its young occupants in sustainable living. The main elements of the project are: man, nature and civilization. The presented pillars of this activity are: the model of coexistence of children, their main activity for the use of earth architecture to create their world, a disciplined life in the area and the ecological footprint of the activity. This activity can also be seen as a social experiment of a possible way to approach sustainable development with economic and ecological issues in a larger scale.
