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.

24. 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.

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

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.
