I live in Leon, a city in the central region of Mexico. In my opinion I think that one stock is the farm land around this city because it provides most of the food required here. Another stock is the high density of the city with almost 1.5 million people. Other stock is the waste because here almost everything is recycled (aluminum, iron, steel, tires, glass, paper, plastic, wood). Also another things such as; furniture, clothes, toys, appliances, construction material, electronics, used cars, are recycled because some of these imported stuff were bought by rich people or companies and years later of use is sold to poor people. The capital of entrepreneurs and companies are a stock because they can invest and create jobs. Close to this city are many water reservoirs and rivers, unfortunately many rives are contaminated but to be positive, this stock is better than nothing. Other stock is the high amount of roads that connect this city with many others. Maybe the centrality of its location could be another stock. The high amount of schools and universities are another stock. Now, to show some flows about. We have a big flow of foreign companies established and working here. The flow of people to work daily is really high. The food flow to this city from the city outskirts is important. Another flow is represented by the construction materials, equipment, electronics, furniture, cars, appliances, and clothes, which come from close places or far countries.
