"This research explores the differential representation of environmental problems through the analysis of characteristic dimensions of the perception of problems today and after 50 years. The conceptualization of an environmental problem as global or local is a matter of special relevance, due to the need to know the way in which people make categories. In this differentiation between global and local environments we find that people are more concerned about global problems, over which they have less influence, than local problems, on which they could act. Research carried out until today shows an absence of links between global and local issues. The empirical research carried out by Uzzell et al (1994; Uzzell, 2000), for instance, demonstrates that people consider environmental problems more serious when they take place further away. This has been called "environmental hyperopia" (Uzzell, 2000). In this work we explore the hypothesis that people will discriminate between local and global frameworks with regard to the location of environmental problems, as well as that global environmental problems will be perceived as more important. Environmental hyperopia will differ depending on whether people perceive the problem as occurring today or after 50 years, because problems are priorized with regard to their remoteness from the subject, and the element of "time" makes problems appear more remote."
