What is the 20th-century problem stemming from rapid urbanization around a city?

Urban sprawl is recognized as a significant issue that has emerged from the rapid urbanization of cities in the 20th century. As populations flock to urban areas, cities expand outward, often leading to the development of residential, commercial, and industrial areas far from the city center. This leap in physical size can result in low-density areas that rely heavily on automobiles for transportation, which can lead to numerous challenges including increased commuting times, loss of natural habitats, and strain on infrastructure.

The phenomenon of urban sprawl typically results from a combination of factors including economic growth, zoning regulations, and the desire for larger living spaces, which can push development further into suburban areas. This not only impacts land use but also has broader social and environmental implications as communities may become more segregated and less sustainable.

While squatting, pollution, and traffic are all important issues related to urbanization, they often arise as consequences of urban sprawl rather than as root problems stemming from urbanization itself. Understanding urban sprawl is crucial for addressing the long-term sustainability and livability of cities in the face of continued population growth and urban development.
