This work studies the currents social change process from a ecological view presented by Guatarri. The praxis reflexive of the ecology puts at the first place the relation man-natur and considers the man as part of the natur while contesting the relations of explotation and domination between the people. A change of values is suggested in order to reach more solidarity and cooperation. Looking for these values, the experience of some ONGs located in the cerrado is discussed. The analysis focuses the strains related to sociability forms in communities and societies.
