I do not have photos taken by me for this exercise but, in general, I could describe the following stocks and flows: 1. People coming to work daily from the metropolitan area to the city (flow) 2. Number of trucks entering the city to bring food from the ouside (flow) 3. The number of green areas in the city to produce oxygen (stocks) - The first could be decreased by producing employment in the neighbor towns to avoid such an amount of people coming every day to the city. - The second one could be reduced with its reduction in CO2 emisions by creating an outside supply warehouses close to the city and then transported by small electric vans into the city. - The green areas (Big parks like the national park within the city), small parks in the neighbors and other reserved bodies of water could be at least kept by avoiding new constructions in protected areas. Note that the picture shows a small river right in the middle of the city which is plenty of vegetation. Bogota is very rich on that.
