Title: What is your worldview?
1What is your worldview?
- Earths resources can support continued economic
growth. - Its 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.
2Expansionist 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.

22Common aspects of environmental problems
- Overpopulation
- Resource depletion
- Pollution
All human environmental problems have their roots
in one or more of the fundamental principles of
ecology.

concerns of sociologists, economists and
ecologists intersect
24The 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.
25Some 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

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.
32The 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.
