Beyond such thoughts on the ecology and economics of the city, we should not forget to redesign the city itself so that in can handle its basic purposes of providing a central location for people to work and live in relative safety. The tasks are diverse and many. The infrastructure and organization of public life are not always developing harmoniously and effectively. The worst heritage of the last century is that the city sacrificed its design and infrastructure to the automobile. It is a model that has no future viability because of the rising cost of oil. The time has come to reconsider community design because of immediate challenges precipitated by rising oil costs, that will bring new mixed land uses, new city management and different organizational forms of transportation to our communities.

Beyond transportation issues, lay health issues. Our population is becoming obese and inflexible due to lack of exercise; this is becoming a crisis among children in Central Florida . Our current automobile-based city design offers unshaded oceans of concrete and asphalt, formidable deserts that are dangerous to cross unless one is in an air-conditioned automobile, all impediments to pedestrian traffic. Urban spaces should be designed in the future so as to encourage exercise and reduce the waste of gasoline. Currently city life can mean bad air, teetering on the narrowest of pedestrian paths, trying to find ones way by zigzagging between parked cars with death defying dashes across 6 lanes of traffic. To encourage walking in the hot Florida sun we must create quality urban space, which includes pleasant microclimates, shaded walks and parking lots – to which plants, particularly trees, make an essential contribution. We must find innovative ways to pay for this vegetative infrastructure like the municipalities getting into the Carbon market by registering their trees and selling the Carbon Credits the trees represent. We must re-orient our cities away from automobiles and toward people. New planning principles and policies placing priority on inviting people to walk and bicycle will do much to remove America 's dependence on foreign oil. Carefully planning for walking and bicycling will evidently serve a much wider agenda. In a time where lively, attractive safe and sustainable cities with healthy individual lifestyles have become important political issues, sending a strong invitation for walking and bicycling will be an obvious way to meet such a policy. So obvious is this route that it may be difficult to find anyone, citizen or politician, who in the present day society does not want a lively, attractive, safe, sustainable and healthy city.
