Urban Sprawl_

1. Urban sprawl, also called sprawl or suburban sprawl, the rapid expansion of the geographic extent of cities and towns, often characterized by low-density residential housing, single-use zoning, and increased reliance on the private automobile for transportation.

2. Urban sprawl is caused in part by the need to accommodate a rising urban population; however, in many metropolitan areas it results from a desire for increased living space and other residential amenities.

3. Urban sprawl has been correlated with increased energy use, pollution, and traffic congestion and a decline in community distinctiveness and cohesiveness. In addition, by increasing the physical and environmental “footprints” of metropolitan areas, the phenomenon leads to the destruction of wildlife habitat and to the fragmentation of remaining natural areas.

4. Urban sprawl refers to a number of related characteristics of suburban development, such as extremely low density for residential development, unique dependence on the car for transportation and street malls and shopping malls as exclusive forms of retail.

5. Critics have charged urban sprawl with a variety of social ills, such as increased pollution, social isolation, destruction of natural resources and even increased obesity. Supporters of suburbanization have challenged these accusations and argued that low density development, with good schools and high levels of safety, is what the vast majority of household desires.

6. People must really like each other. Although we live in one of the world’s largest countries with an endless horizon of space, we choose to live right next to each other in our cities. Over 80% of us now live in urban areas. As our cities grow bigger, urban sprawl is beginning to affect our quality of life.

7. The most obvious problem is that sprawl leads to a car-dependent culture—and driving is stressful for drivers and for nature. More traffic, more carbon emissions, more smog! But sprawl isn’t inevitable. It is often the result of poor planning and short-sightedness.

8. Sprawl affects us in surprising ways—like draining our precious free time and expanding our waistlines. A commuter who drives just one hour each day spends the equivalent of nine working weeks a year in a car. Researchers have found that people living in sprawling suburbs spend less time walking and weigh up to six pounds more than those living in pedestrian-friendly neighborhoods.

9. Urban sprawl is cutting into precious farm and wildlands, leaving us with less greenspace and precious wildlands, like bogs, which are being drained and paved over, putting valuable wildlife habitat and species at risk.
