"To assume the progressive paradigmatic change which goes from the "objectively defined problem" to the "socially constructed problem" demands taking a second look at environmental problems in order to analyze them in terms of relationships, processes and contexts. Furthermore, it demands reconsidering that underlying the definition and exploration of the same, lie social values which enter into conflict. (Álvarez, 2001) It is precisely this reflection on the hierarchy of social values which has allowed to delve deeply into the analysis of environmental concern (Stern, Dietz y Kalof, 1993; Thompson y Barton, 1994). It has also allowed to suggest the importance of directing the researchers attention to the different socializing institutions which transmit and shape value orientations, in as much as it is not possible to disconnect environmental attitudes and beliefs from their specific social, temporal and cultural contexts."
