This document explores the concept of urbanization, examining its role in shaping modern society and the healthcare system amidst a growing population. It raises the question of whether euthanasia and eugenics should be embraced by governments as solutions to healthcare demands. The rapid urbanization due to agricultural surpluses and the industrial revolution has led to specialized professions, class structures, and political hierarchies, resulting in a significant shift in population dynamics. The challenges posed by sprawl and reliance on fossil fuels are also discussed, alongside the essential role of planning and zoning in managing urban growth.

What is the significance? • What is this picture of?
Homework • Homework Chapter 13 pages 344 – 349 • Question: With the ever growing population and the demand on the current health care system, should euthanasia and eugenics be practiced by the government? • For next class be able to explain what is euthanasia and eugenics?
Growth • Urbanization = the movement of people from rural to urban (cities and suburbs) areas • Society’s greatest change since it became sedentary • Urban populations are growing rapidly • The growing human population • More people are moving to urban areas
Growth • Urbanization began when agricultural surpluses allowed people to leave their farms • Creating specialized manufacturing professions, class structure, political hierarchies, and urban centers • The industrial revolution spawned technology • Creating jobs and opportunities in cities • Increasing production efficiencies • In 1950, 30% of the population was urban; today, it’s 49% • Urban populations will double by 2050 • Rural populations will decline by 16%
Why cities grew Cities grew to bring the labor force closer to the factories and because cheap housing. Cities grew because of climate, topography, and waterways determine whether a small settlement becomes a large city
Where is this? • What is the significance of this picture? • This is roughly where Fenway Park is located. • Filled in to allow growth of the city, hence the term Backbay.
New Material • Who came up with the idea of highways and why? • President Eisenhower. • To evacuate the population in the event of a nuclear war. Could this be achieved successfully today? • Lead to greater growth of the country and more movement by people.
New Material • How did our society develop: • 1st Hunter / Gathers • Farmers • Development of the cities • People move away from the cities but people still want easy access to the cities.
New Material • Urbanization began when agricultural surpluses allowed people to leave their farms • Creating specialized manufacturing professions, class structure, political hierarchies, and urban centers • The industrial revolution spawned technology • Creating jobs and opportunities in cities • In 1950, 30% of the population was urban; today, it’s 49% • Urban populations will double by 2050 • Rural populations will decline by 16% • What is / will be the impact?
New Material • Today, cities thrive in resource-poor areas • Cheap fossil fuels and powerful technologies (Dallas) • Water is brought in from distant areas (e.g., Las Vegas) • Cities in the southern and western U.S. have grown • Why? • People (retirees) moved from northern and eastern states. Why Texas, Arizona & Florida? • Warmer weather, lower taxes • Phoenix grew 91% between 1990 and 2008
New Material • How & Why did the suburbs develop? • Millions commute to downtown jobs from suburban “bedroom communities” • Sprawl = the spread of low-density urban or suburban development outward from an urban center
New Material • What is the purpose of planning and zoning?
New Material • Sprawl
New Material • When sprawl started in the modern age. • Following WW II, the government passed the GI Bill. How did this impact housing construction?
Space of the suburbs • Note the growth and water is limited
Problems with Sprawl • Economists, politicians, and city boosters think growth is always good, but is it? • Transportation: people are forced to drive cars • Lack of mass transit options • More traffic • Increases dependence on nonrenewable petroleum • Pollution = carbon dioxide, air pollutants, ozone, smog, acid precipitation • Motor oil and road salt from roads and parking lots
