I'm from the DC metro area. First, identify the most important stocks and flows (at least three) entering, staying in and eventually leaving your area (or city). 1. People 2. Construction materials 3. Food Describe your findings based on the concept of stocks and flows by presenting the necessary information or examples. 1. I live in a job-generating area, mostly related to the federal government. Many people living in the area are not locals and did not grow up in the area. They stay for work. Eventually, when they retire, they will likely move away. 2. Due to the population density of the area and the high value of land, residential and commercial buildings are being built and more development is happening. The materials are imported from other areas. During the lifetime of the buildings, the materials will stay in the area. Once the lifetime of the building is up, the building is demolished and the material is taken elsewhere to be dumped. 3. Most food is imported from elsewhere and there may be a few local farms in the neighboring rural areas. The food is purchased and consumed. Eventually, the food is processed and digested and eventually excreted. The excrement is when the "food" leaves. Imagine and shortly describe how these stocks and flows could change in the future for the benefit of your area. Due to the increase in population, the stocks will increase, the in-flows will increase and the out-flows may decrease.
