SCI 1102 Lecture Notes - Lecture 4: Smog, Light Pollution, New Urbanism
Document Summary
Urbanization: movement of people from rural to urban areas (cities/suburbs: people need clean, safe urban environment, high quality of life, must minimize ecological footprint. Industrialization has driven urbanization: urban populations growing, urbanization began when ag surpluses allowed people to leave their farms. Increased production efficiencies: urbanization has slowed in developed nations. Population lives in suburbs: developing nations urbanizing rapidly. Ppl searching for jobs, fleeing wars, ecological damage. Population growth often exceeds economic growth resulting in pollution, overcrowding, and poverty. 23 megacities of over 10 million people: people have moved to suburbs. By mid 1900s, immigration & trade had increased urbanization. Affluent people moved to suburbs for more space, economic opportunities, cheaper real estate, less crime, better schools. People now commute to downtown jobs & live in suburban areas. Technology allows people to work in any area. Sprawl: the spread of low-density urban or suburban development outward from an urban center (physical spread of development faster than population growth)
