The+City

**The city is a complex system. The neolithic revolution brought agriculture and with agriculture, people started to settle down. This is when the cities started to be created. In the past the walls were the ones that defined the cities and from the Industrial Revolution they started to grow really fast. The city provides protection to us. We have 4 functions for the city: We need a house, a working place, a recreational place and a place to walk. In the city we can find ghettos. People usually think that a ghetto is only for poor people, but this is not like this. The ghettos are groups of equal citizen. So there can be a ghetto of rich people and a ghetto in the lower society. The ghettos are isolated from the rest of the city. They also help increase urban disorganization. ** 

 The city is a place to interact with other people. Every city is different and we need to learn how to walk through the city and enjoy what we’re seeing. **
 * There are three things that make a sustainable city: **
 * **Economy **
 * **Ecology (human are part of nature and the communities are responsible to take care of it) **
 * **Equity (same participation, same oportunities) **
 * A good city is the one where the people wants to go out, walk around the city and enjoy it, without being afraid of the insecurity or anything.
