What are the effects of urbanization on geographical landscapes?.

Urbanization alters geographical landscapes through increased land use for housing, infrastructure, and commerce. It leads to habitat loss, changes in natural water drainage, and increased pollution. Urban heat islands emerge due to concentrated human activities, affecting local climates. Recognizing these effects helps inform urban planning and environmental management.
