The most important stocks and flows entering my city are: 1) People, 2) Electricity 3) Food People continuously come into my city from areas outside of it (smaller communities) because in my city there are bigger opportunities for work and education - they temporarily enter the city during the weekdays, to work or study, which increases the density of people and has to be taken into account by city planners. Food must always be imported from the farms further away from the city, and electricity must be wired from power plants into the city center. For these to benefit this area in the future, we must maximize the city's capability to utilize them sustainably - how can we transport these commuting people efficiently? How can we sustainable and efficiently create a network for electricity? How do we minimize carbon emissions during food transport? If we answer these questions, we can benefit from our answers.
