Ecumenopolis - Ecumenopolis (from Greek: οἰκουμένη oecumene, meaning "world", and πόλις polis "city", thus "a world city"; pl. ecumenopolises or ecumenopoleis) is the hypothetical concept of a planetwide city. The word was invented in 1967 by the Greek city planner Constantinos Apostolou Doxiadis to represent the idea that in the future urban areas and megalopolises would eventually fuse and there would be a single continuous worldwide city as a progression from the current urbanization, population growth, transport and human networks. According to Doxiadis, it was the fifteenth level of ekistic units and the most significant one as the uppermost echelon of the classification. This concept was already current in science fiction in 1942, with Trantor in the Foundation series. When made public, Doxiadis' idea of ecumenopolis seemed "close to science fiction", but today is "surprisingly pertinent" according to geography researchers Pavle Stamenovic, Dunja Predic and Davor Eres, especially as a consequence of globalisation and Europeanisation.
