Human history is dialectical -- good and bad at play. There are progressions that look like we are improving and regressions that look like no improvement will endure. I have been working on ideas of technological salvation from such adversities as pollution, starvation and pandemic disease. The past 2 weeks has been ( let's be nice) a festival of confusion, exaggeration and misinformation about influenza viruses. Influenza was invented as a distraction from the US economic castrophe, and destruction and killing in many countries, far away. Let a us take a little holiday and imagine how cities of the future might become healthy, sane environments.
William Rees, an economist at the University of British Columbia took an ecological approach to economics. He is concerned that cities are growing too large to be sustainable. Cities are centers of consumption and depend on the surrounding environment to supply energy, food and to accept and disperse waste. Rees has measured the ecological footprint of cities and his results are not encouraging.
City states are depleting these resources at an alarming rate – fish stocks are depleted; soils are depleted, washed or blown away; fresh water supplies are marginal, depleted or contaminated; the air is polluted and ozone depletion combined with global warming from increased greenhouse gases threatens progressive and erratic climate changes. Climate changes threaten agriculture, as we know it.
At the end of the 20th century, 1.1 billion people live in large cities with populations in the millions; their carbon dioxide emissions are greater than the capacity of all the world’s forests to process the gas. One city person requires at least five square hectares of high quality land to support him or her. The 500,000 people living in the city of Vancouver on 11,400 hectares of land actually require the output of 2.3 million hectares of land. The real capital is not money but air, water, food and other resources.
Many scientists have imagined major disruptions of city-states with civil disobedience and armed conflicts arising from the competition for scarce resources. Solutions are available but are improbable, given our basic tendencies.
A sane, rational city-state would limit its growth; limit its pollution and progress toward food, water and air sustainability. If all long-distance supplies were blocked could the citizens of a city continue to live comfortable, healthy lives? One criterion of a sane city would be self-sufficiency. To make cities more livable and less polluted, car use would be reduced to less than half of current levels and car-free zones would restore healthier living conditions for many citizens.
For many urban dwellers, advanced electronic networking would reduce the need for commuting and long-distance travel would be considered a luxury and rationed. The need to transport food and goods would be reduced by increased local production. The transportation of goods would be streamlined into centrally controlled supply lines that achieve maximal efficiency. We could advance toward intelligent distribution systems such as large pneumatic or electromagnetic tubes that send containers between city centers at high speed with minimal pollution. It is absurd to have goods distributed in trucks, in traffic, chaotically with no cost effective distribution plan. Food can be grown and processed within a city by returning some of the land area to market gardens and intensive greenhouse technology.
Each city would have to renew and support a surrounding agricultural zone. Cities would essentially backtrack about 100 years when food supply lines were shorter and farmers living adjacent to the cities could supply most of the food. Cities, like cancers have grown unchecked, metastasized and destroyed much of the support system they used to enjoy. The humanity of a city can be restored by creating living arrangements that promote a return to groups of individuals that know each other and can relate to each other – small communities.
Local groups can relate to their natural environment and can return to an understanding of how to supply their own needs. If a group does not have a natural environment that they relate to, then the group will be dysfunctional and members of the group will be sick animals. If a group grows too large for individuals to know and relate to each, then the group will be dysfunctional – sick humans.
In poor countries, images of attractive, well-dressed people whose main job appears to be enjoyment and adventure create immediate dissatisfaction with local life. The happy and adapted poor become the dissatisfied and disenfranchised who abandon traditional ways of life for jobs that are often transient, demeaning and fail to deliver the wealth necessary to achieve the glamorous movie-magazine lifestyle.
Humans continue to have basic needs – shelter, food, safety and sexual privileges. Getting connected to affluent media in a poor village in Africa is counterproductive without opportunities to apply new desires, knowledge and ideas.
We would do better to encourage restoration of local economies and expand efforts to reduce overpopulation in areas that cannot support the population. New methods of resolving conflicts are required. Funds to rebuilt decaying agricultural and community infrastructures are needed. Before communication networks look attractive, their information content must be relevant and supportive of the recipients’ needs.
