As a child I lived in several big cities abroad and I remember a feeling of estrangement when visiting my native Norway. Used to a life in an urban environment, the untouched nature felt both frightening and enticing, familiar but strange. Freud described this feeling with the term “das Unheimliche” – a feeling that something once known and safe, feels uncanny, strange and eerie. A feeling echoed by the prospects the world faces today.
