The photo is a bird view of the community I'm currently live in. The three key stock and flows I believe are: People, Electricity(Energy), Food and water. People stay, or move in/out of the community affects the consumption of electricity(energy) and food and water; Electricity(energy) and food and water stock and flows depends on the people present or will present in the community.
