Urban sprawl, the spreading of large developments of housing and shopping areas around a city’s center, has many negative cultural and environmental effects. Sprawl increases traffic congestion along highways. The residents who live in these faraway suburbs often work downtown, where the majority of businesses are still located. They have to undertake long commutes to and from work every day, which limits their time with family and friends and increases their time alone on the road. These longer commutes also result in increased air pollution that can lead to smog problems for the city.
