Detailed explanation-1: -An urban area is the region surrounding a city. Most inhabitants of urban areas have nonagricultural jobs. Urban areas are very developed, meaning there is a density of human structures such as houses, commercial buildings, roads, bridges, and railways.

Detailed explanation-2: -One type of development pattern that has received increasing attention by researchers and policy makers interested in fostering sustainable communities is called “sprawl.” Sprawl is generally typified as low-density, haphazard development spiraling outward from urban centers (Burchell et al. 1998).

Detailed explanation-3: -Urbanization often results in deforestation, habitat loss, and the extraction of freshwater from the environment, which can decrease biodiversity and alter species ranges and interactions.

Detailed explanation-4: -Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people. Concentrated energy use leads to greater air pollution with significant impact on human health. Automobile exhaust produces elevated lead levels in urban air.

Detailed explanation-5: -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.
