In the Biblical deluge there is a clear relationship between the ecological disaster and man's feelings of guilt because of his aggressive fantasies. Man's actions precipitated the disaster; he was unable to control his aggression and God meted out justice. In Sumerian literature the gods (who had human needs and impulses) destroyed the earth because they could not control their 'ecocidal' drives. In a recent novel by G. Garcia Marquez, Cien Anos de Soledad, man is destroying the earth to protect immediate economic interests. In all cases there is a lack of development of ego functions, especially reality testing. Man controls his behavior poorly in relation to the eco-system and when he recognizes the consequences, it is too late to repent. The author concludes that mythology and the novel suggest the existence of 'ecocidal' fantasies: man with destructive impulses toward his own milieu.
