Urbanization is increasing air pollution as cities grow larger and require more space, converting natural areas and increasing travel. To develop cities sustainably, transportation, land use, and urban form must be integrated, with a focus on people rather than vehicles. An effective spatial strategy would include compact development, mixed land uses, mass transit, and green spaces to reduce sprawl and pollution.

2. Urbanization as a physical process (1) Urban area Periphery area Urban attracts people to come and settle

3. Urbanization as a physical process (2) On the other hand, City needs more spaces to keep growing Urban area Periphery area

4. Urbanization as a physical process (3) Urban area Periphery area Urban size is getting bigger More natural areas converted Urban load is getting heavier More travels occur More air pollution
