Despite having been regarded as a series of “externalities” by conventional systems of economic thinking, our natural environment is not merely a backdrop to human activities, but is the very base upon which all human systems are built. This reality is certainly not new to sustainability science, but it is easy to lose sight of our close dependence on natural ecosystems when it comes to living in urban environments. Amidst the concrete, buildings, and tightly managed green spaces, it can be hard to see the natural environment — the nature – that exists in cities when we’re so used to “nature” being something you find in national parks and preserves, fenced off and isolated from the places we live and work.
