The City as "Closed Loop"

Dickson Despommier says that the goal of cities today should be to be a "closed loop" ecosystem, where everything that is needed to support the city - energy, food, etc. - is contained within its borders.

Despommier looks to the natural world as a model for urban growth management:

"I would encourage all city planners and developers to take a long, hard look into the ways in which ecosystems behave. It is the model for how we should be handling things like water management, energy utilization, and the recycling of waste into usable resources. In an ecosystem, assemblages of plants and animals are linked together by a common thread: the sharing of nutrients, the transfer of energy from sunlight to plants and then to animals, and the recycling of all the elements needed to ensure the survival of the next generation of those living within the boundaries of that geographically defined area."
