What is your worldview?

What is your worldview?. Earth’s resources can support continued economic growth. It’s not possible to protect the environment without having a growing economy. Problems created by past technologies will be solved by future technologies. Perpetual growth is both good and possible.

  1. What is your worldview? • Earth’s resources can support continued economic growth. • It’s not possible to protect the environment without having a growing economy. • Problems created by past technologies will be solved by future technologies. • Perpetual growth is both good and possible. • Nature is a storehouse of raw materials to be used to satisfy increasing human needs. • Continued material growth is necessary to increase human quality of life. • Technological innovations can sustain an ever-increasing human population. • Progress means the satisfaction of increasing levels of human wishes. • Development means essentially the same thing as growth. • There is always an “away” to throw things to.

  2. Expansionist Worldview: Material Growth is necessary for human happiness and is possible because of an ever-advancing technology and abundant resources.Ecological Worldview: Earth is a finite system that cannot exhibit endless growth. • All ten statements reflect beliefs of the Expansionist Worldview. • If you agreed with seven or more of the statements, count yourself among the Expansionists. • If you agreed with three or less, you probably hold the Ecological View. • Scores from four to six suggest your worldview is mixed.

  18. Acid deposition in the United States

  19. Common aspects of environmental problems • Overpopulation • Resource depletion • Pollution • Changes in values All human environmental problems have their roots in one or more of the fundamental principles of ecology.

  20. Sustainable: Providing humans with a better life without depleting resources that will harm future generations. Fig. 1-9. Sustainable solutions require that the concerns of sociologists, economists and ecologists intersect

  21. The human factor – a brief look into the past (Ch. 2 p 49-52) • Neolithic Revolution • The development of agriculture by humans some 10,000 years ago leading to more permanent settlement and population increases. • Industrial Revolution • The development of manufacturing processes using fossil fuels and based on the application of scientific knowledge and technology (19th century). • Environmental Revolution • A change in the adaptation of humans to the rising deterioration of the environment.

  22. Some U.S. History of environmental problems • Late 18th- early 19th century - European explorers claimed new lands. Deforestation, farming, settlement and introduction of new plants, animals, and diseases. • 19th century - frontier moved ever westward, land development, growing population • Mid 19th century - Onset of industrialization  resource depletion, pollution, but also start of first environmental movements

  23. Some U.S. History of environmental problems • Late 18th- early 19th century - European explorers claimed new lands. Deforestation, farming, settlement and introduction of new plants, animals, and diseases. • 19th century - frontier moved ever westward, land development, growing population • Mid 19th century - Onset of industrialization  resource depletion, pollution, but also start of first environmental movements • 1930s - Conversion of large tracts of former prairie to farmland. “Sod busting”, dustbowl of the 1930, depletion of soil resources  spurred conservation movement

  24. 1930s Dust Bowl

  25. Some U.S. History of environmental problems • Late 18th- early 19th century - European explorers claimed new lands. Deforestation, farming, settlement and introduction of new plants, animals, and diseases. • 19th century - frontier moved ever westward, land development, growing population • Mid 19th century - Onset of industrialization  resource depletion, pollution, but also start of first environmental movements • 1930s - Conversion of large tracts of former prairie to farmland. “Sod busting”, dustbowl of the 1930, depletion of soil resources  spurred conservation movement • Early 1950s - rapid industrialization, fast population growth (“baby boom”), cheap energy • 1960s, civil activism and environmental activism (Cuyahoga River fires, Rachel Carson’s book ‘Silent Spring’ 1962), development of environmental laws and regulations.

  27. Some U.S. History of environmental problems • Late 18th- early 19th century - European explorers claimed new lands. Deforestation, farming, settlement and introduction of new plants, animals, and diseases. • 19th century - frontier moved ever westward, land development, growing population • Mid 19th century - Onset of industrialization  resource depletion, pollution, but also start of first environmental movements • 1930s - Conversion of large tracts of former prairie to farmland. “Sod busting”, dustbowl of the 1930, depletion of soil resources  spurred conservation movement • Early 1950s - rapid industrialization, fast population growth (“baby boom”), cheap energy • 1960s, civil activism and environmental activism (Cuyahoga River fires, Rachel Carson’s book ‘Silent Spring’ 1962), development of environmental laws and regulations. • 1970s – energy shortages, new laws, scientific search for alternative energy sources. First Earth Day. Environmental movement - first local and regional issues, then national and global concerns • 1980s – (perception of) too much government intervention  slows meaningful clean-up (‘Superfund’). • 1990 – present - Increased recognition for longer term, more global concerns.

  28. The growth and industrialization in the U.S. and Europe in the early 1950s was in large part due to • government intervention. • environmental activism. • the first law of thermodynamics. • the discovery of gold out west. • cheap energy.
