Examples of stocks and flows: 1. Garbage. For now it is a flow which only goes out of the city. But in the future garbage may also become a stock as it could be used as for example compost, building material or for reclaiming land. 2. Bike-sharing. It is a stock that is becoming more and more popular. This shows how means of transportation instead of being a few are becoming a stock. This also exists with other vehicle types as cars or scooter. 3. Artworks. An important stock which defines the cultural value of the city. London has a rich artwork collection which rises it's popularity among tourists.
