Through watching the films of “My Brooklyn” and “Citizen Jane: Battle for the City”, we see that it is impossible to avoid the changes along with the developments of cities. As we see, most power which used to decide a change was held by the government or some other industries. Old streets and old systems created a specific environment and safety for our public life, however, when it becomes an obstacle for the development of a city, personal property or privatization will no longer be respected. We appreciate what had done by Jane on battling on the decision of tearing up the entire neighborhood. Without her hard work, we would not know what New York would be like today. Still no one will blame on the heavy traffic in New York today because that was how it is like always. But this situation will not last forever, since people and city are always counted as a whole and the thoughts of people are always keep changing, the original cities will be changed along with the developments of society eventually.
