A city, in the words of urban sociologist Robert Park, is man's most successful attempt to remake the world he lives in more after his heart's desire. But, if the city is the world which man created, it is the world in which he is henceforth condemned to live in.
Thus, indirectly, in making the city man has remade himself. Which begs the questions; what kind of city have we made for ourselves? How has the unprecedented, rapid urbanisation and population growth rate contributed to our well-being?
