As drought conditions continue year after year in California, the humans who live here attempt to maximize their supply of water. We need more fresh water for the continually growing population of the state. Our intense focus tends to obscure the need other creatures and habitats have for water. We're continually surprised when the animals follow the water into the cities.
Those of us in urban areas tend to view nature as something over there. A place you get in your car and drive to; a series of beautiful scenic postcards viewed through the windshield as we wind our way through the nature reserve. When it comes to preserving nature, it's a question of leaving undeveloped what is currently undeveloped. From the point of view of our global industrial economy, “nature” is unfulfilled potential; a state we allow to persist as a form of charity. A gift we give to ourselves and our posterity.
Meanwhile, ravens and raccoons have become residents of the urban landscape. The garbage we generate on a daily basis provides sustenance for an ever growing population. Squirrels and deer seek food and water in our gardens. Mountain lions follow their prey into suburban neighborhoods. Coyotes establish a presence in Golden Gate Park and humans walking their dogs are warned of the potential danger.
When our perception of the order of things is ruptured by an animal that intrudes on human space, our impulse is to set things right. Our moral standard is a judgement on whether or not the intruder is a clear and present danger to humans. Mountain lions are killed or captured. For the time being, coyotes are are allowed to live in the park. Deer, ravens, raccoons and squirrels are all tolerated with the proviso that they really shouldn't be here. We do not contemplate a path to citizenship.
Our futurists tell us that big and bigger cities are the answer to the efficient use of our diminishing natural resources. Our search is for a solution that allows more and more humans to subsist on the earth. Optimization requires a concentration of resources; global supply chains will connect a small number of very large urban hubs with the requisite resources. Every inch of the globe will be assessed based on its contribution to maintaining the network of mega-urban hubs. Of course, this kind of concentration increases the risk of catastrophic events. They used to call this kind of thing, “putting all your eggs in one basket.”
As we think about the design and architecture of these mega-urban spaces, we may believe that we act ecologically merely by virtue of moving toward “concentrated urban” over “broadly distributed rural.” The clever reversal is that “getting back to nature” now means getting much more densely packed and urban.
While there's some truth in this approach, it's not fully ecological because it's vision is limited to human social space. Does it take the deer, raccoons and ravens into account? Do they have a place in this new urban environment? What about coyotes, will they be welcome in the mega-urban future? Whether we plan for them or not, they're already citizens of our urban landscape. And as global warming continues to materially change the zones we've designated as “nature,” more species will cross the border into the urban zone in search of relief and a new life.
Today we have an architecture that is unable to anticipate that its buildings will have to coexist with pigeons in the shared urban landscape. Tomorrow (or rather today) we'll need to learn to coexist with a growing and increasingly diverse population of urban wildlife. And our questions may have to go beyond how coyotes and humans will coexist to how red tailed hawks and ravens will interact within our built mega urban enclosure.
