Sprawl

Spread what you are spreading. Once upon a time, contagion was a fairly neutral term used to represent low density economic growth that relied on cars over the old suburbs. It is almost completely used to explain the dark side of this growth such as intolerable traffic volume, annihilation of open land, increase of air pollution and water pollution, tax rise, new school, sewerage, road permanent I will. Turn it. This is what the old residents of the suburbs feel.

Urban expansion, also known as sprawl or suburban sprawl, is a rapid expansion of urban geography, characterized by increased dependence on low-density housing, single-use zoning, and private car transport. Part of the reason for urban expansion is the need to adapt to increasing urban population; but in many metropolitan areas this is because people want to increase their living space and other housing facilities. Urban expansion is related to energy use, increased pollution and traffic congestion, and a decline in community uniqueness and cohesion. Furthermore, by increasing the physical and environmental "footprint" of metropolitan areas, this phenomenon results in destruction of wildlife habitats and fragmentation of the rest of the natural areas.

There are many factors leading to the expansion of the city. As shown in the above statistics, population growth alone does not account for urban growth in the metropolitan area. Often the urban spread occurs in areas with a declining population, and in areas where the population is increasing, especially in developing countries, the expansion of the city is rare. Economic growth and globalization are regarded as the main macroeconomic factors of urban expansion, but richness, attractive land and housing prices, and more comfortable large-scale housing (eg courtyard, home appliance) storage space And the need for privacy plays an important role at the individual level. Many experts also believe weak planning methods and disposable zoning will also lead to city expansion.

Supporters of urban expansion believe that living in the suburbs other than major cities is a matter of personal choice and freedom. In addition, they can bring various benefits of urban expansion, such as short-term economic growth and increased employment caused by new buildings. However, the spread of the city is receiving increasing attention in the United States. When choosing your next home, consider the negative impact of urban expansion and the impact it will have on you, your community, and the environment. Expansion of development can cause water distribution problems and lead to excessive water consumption. Typical low density or suburban communities use more water than high density urban communities. Landscaping is the main cause of excessive use of water. In the US 30% of the water used daily for outdoor use
