Chapter 22: Urbanization and Sustainability
|
Section 1: What are the Major Population Trends in Urban Areas?
Concept 22-1: Urbanization continues to increase steadily, and the numbers and sizes of urban areas are growing rapidly, especially in less-developed countries. Section 2: What are the Major Urban Resource and Environmental Problems?
Concept 22-2: Most cities are unsustainable because of high levels of resource use, waste, pollution, and poverty. Section 3: How Does Transportation Affect Urban Environmental Impacts?
Concept 22-3: In some countries, many people live in widely dispersed urban areas and depend mostly on motor vehicles for their transportation, which greatly expands their ecological footprints. |
Section 4: How Important is Urban Land-Use Planning?
Concept 22-4: Urban land-use planning can help to reduce uncontrolled sprawl and slow the resulting degradation of air, water, land, biodiversity, and other natural resources. Section 5: How Can Cities Become More Sustainable and Livable?
Concept 22-5: An eco-city allows people to choose walking, biking, or gas transit for most transportation needs; to recycle or reuse most of their wastes; to grow much of their food; and to protect biodiversity by preserving surrounding land. |
