I think the main stock and flow in Tehran are: Peoples so with them there are more stocks and flows such as vehicles, transport, food, and water. The flow of people in my country is very important because every day a lot of people immigrate in Tehran from near small cities to go their jobs and schools because Tehran is an Advanced city both economically and financially. As a result of this migration as well as residents of Tehran, a lot of people use their cars or public transport in order to go their jobs and schools, in it cause traffic. Besides, these people consume a lot of food and water during the day. Plus , I must add that Transport is a big flow because most of the people need to use public transport and it causes contamination of the cities. I think that in the future it's necessary to find a sustainable way to continue using this stocks and flows, for example, we need to improve other ways to use the transport in order to decrease the production of CO2. In addition, we must find Intelligent ways to use this huge everyday immigration to Tehran.
