In urban ecology, we now view cities much like other ecosystems and living entities by using the concept of "urban metabolism". Essentially, we can best understand how cities work by looking at the flows of energy and materials through an urban area. It really is the same as making a budget. If we use more resources than we create, we are operating at a deficit. That of course is unsustainable. BUT... think about it -- cities cannot possibly make all their own food, water, and energy within their own boundaries, and they certainly cannot house their own waste inside city limits. (Just like non-human ecology.) So technically, cities cannot be sustainable unless we look at them in the context of their surrounding landscape. This is the necessary approach we will take in this module. But first, we need to become grounded in the concept of urban metabolism. This is an introductory exercise; later we will specifically measure these flows of energy and materials in sample cities around the world.
