Just as we do, but our fields are not being fully utilized when they are overran with housing. We have hundreds of square miles covered with industrial centers, beckoning commuters, and encouraging mass transport during national distribution. We do not live within a stroll of our markets, and our markets are not located within a reasonable distance from the manufacturers/producers. We have FAILED to create sustainable community structure/development. So what will cost more....trying to restructure, environmentally and logically, or drilling & lowering oil to continue an utterly unsustainable way of life?
At some point, we will always fail, despite what innovations are developed. We cannot sustain 100-200 miles of commuting a day per person (environmentally, psychologically, logistically). We need more local marketplaces, more local production, more local utilization (while preserving national infrastructure to compensate for shortages/surplus and market demand adjustments). Hell, when some goods are becoming more expensive coming from China (due to transport costs), then Id assert they would be cheaper made in your neighborhood than a plant across the country (no matter how efficient that other plant is). We definitely need more local production and our economy can support such, without devastating other national production centers (which have experienced much more competition from overseas recently anyway). In many ways, if we approach this problem properly, we can address many national & environmental issues at once.
On average (perhaps not for you) it is still quite affordable (distance vs hours of work to go that distance). It is the same price of milk, cheaper than most soft drinks and beer, cheaper than a dinner, etc.
BTW, not that you can draw theories from maps, but take a look at:
