Urbanization is one episode in a 1973 series, On Ecology, produced and directed by Samuel Hudson. This episode takes a look at the modern city. Rather than focusing on facts and statistics, the film consciously mimics an academic lecture and approaches its topic through a philosophical lens. Lecturer John O'Connell uses various literature to form a relatively grim look at American cities, including Democratic Vistas by Walt Whitman and The Urban Unease: Community vs. City by James Q. Wilson. The film also includes photographs, paintings and brief interviews.
