ABSTRACT
Although ecological crises are by no means a new phenomenon in the history of humankind,1 the present environmental problems and their perception show some peculiarities that deserve attention. For the first time in history it seems that not only specific cultures and societies are endangered but the whole world population: the species Homo sapiens. In addition, it is assumed that the environmental changes may lead to political and economic destabilization on a global scale with unforeseeable effects.2
