Psychoanalytic Ecology applies Freudian concepts, beginning with the uncanny, to environmental issues, such as wetlands and their loss, to alligators and crocodiles as inhabitants of wetlands, and to the urban underside. It also applies other Freudian concepts, such as sublimation, symptom, mourning and melancholia, to environmental issues and concerns. Mourning and melancholia can be experienced in relation to wetlands and to their loss. The city is a symptom of the will to fill or drain wetlands.
