Safeopedia explains Sprawl
Urban sprawl occurs when people abandon the densely populated or crowded central parts of a city in favor of suburban areas with large space, previously home to wildlife and farms. There are many factors involved when considering the cause of urban sprawl, but reasons include a preference for larger houses and larger lawns or over-dependence on motor vehicles. Urban sprawl can have negative effects like increased pollution and water consumption, as well as a loss of wildlife.
