Title: Ch. 3: Addressing Environmental Problems, Part II
1Ch. 3 Addressing Environmental Problems, Part
II
21
- Briefly outline the history of the conservation
and environmental movements in the United States.
318th and 19th Centuries
- Many Americans during this time had a frontier
attitude to conquer and exploit nature, areas of
the Midwest the size of Europe were completely
deforested by the 1860s - 1891 the General Revision Act passed giving
president authority to establish forest reserves
on public land.
4Early 20th Century
- President Theodore Roosevelt used General
Revision Act to keep 17.4 million hectares of
forest away from loggers, but would later be 6.5
million hectares of 21 designated national
forests. - Yellowstone in Idaho, Montana and Wyoming became
the 1st national park followed by Yosemite and
Sequoia in California.
5Late 20th Century
- Environmentalists from the Sierra Club and
National Wildlife Federation began voicing their
concerns about the environment - 1970 was a big year marking the 1st national
Earth Day, and the formation of the Environmental
Protection Agency (EPA) which signed National
Environmental Policy Act (NEPA) into law that
year.
62
- Describe the environmental contributions of the
following people John James Audubon, Henry David
Thoreau, George Perkins Marsh, Theodore
Roosevelt, John Muir, Gifford Pinchot, Franklin
Roosevelt, Aldo Leopold, Rachel Carson, and
Gaylord Nelson.
719th Century Naturalists
- John James Audubon Aroused American interest in
nature with his paintings - Henry David Thoreau Wrote Walden Pond about
living in harmony with nature - George Perkins Marsh Wrote Man and Nature about
how humans are agents of environmental change
820th Century Conservationists
- Theodore Roosevelt Used General Revision Act of
1891to create 24 million hectares of national
forests - Gifford Pinchot 1st head of U.S. Forest Service
- Franklin Roosevelt Created Civilian
Conservation Corps and Soil Conservation Service - Aldo Leopold Wrote Game Management and A Sand
County Almanac about the need to conserve
wilderness areas
9Other Great Environmentalists
- John Muir - Helped Establish Yosemite and Sequoia
National Parks and founded the Sierra Club - Rachel Carson - Wrote Silent Spring about the
dangers of pesticide use - Gaylord Nelson - Former Wisconsin Senator
organized the 1st Earth Day
103
- Explain why the National Environmental Policy Act
is the cornerstone of the U.S. environmental law.
11The National Environmental Policy Act
- The National Environmental Policy Act (NEPA) was
signed into law shortly after the Earth Day
movement in 1970. - It requires that the federal government consider
the environmental impact of any construction
project funded by the federal government.
12Why the NEPA is Great
- NEPA provides the basis for developing detailed
environmental impact statements (EISs) to
accompany every federal recommendation or
proposal for legislation. - Established the Council on Environmental Quality
to monitor the required EISs and report directly
to the president.
13More Reasons to Love the NEPA
- NEPA oversees federal highway construction, flood
and erosion controls, military projects, public
works, and federal agencies oversee nearly 1/3 of
the land in the United States - This act has influenced environmental legislation
in many states and other countries.
144
- Relate why environmental impact statements
provide such powerful protection of the
environment.
15Environmental Impact Statements
- Help federal officials make informed decisions
- EIS must include nature of proposal and why its
needed, short-term and long-term and any adverse
environmental effects, and alternatives to the
course of action to lessen adverse effects.
16More Information About EIS
- Courts decreed the documents had to be thoroughly
analyzed the environmental consequences of the
anticipated projects on the soil, water, and
organisms. - EISs must be available to the public.
17Negative Views of EIS
- Some environmentalists say environmental impact
statements are incomplete or ignored. - Others claim theyre too involved, take too long
to prepare, and are targets of lawsuits.
185
- Sketch a simple diagram showing how economics is
related to the environment.
(Economics and Environment both love the green!)
19Marginal Cost of Pollution
20Marginal Cost of Pollution Abatement
21Cost-Benefit Diagram
226
- Distinguish among the following terms marginal
cost of pollution, marginal cost of pollution
abatement, optimum amount of pollution.
23Marginal Cost of Pollution
- The cost, in environmental damage, of a unit of
pollution that is emitted into the environment - As the total amount of pollution increases, the
harm done by each additional unit also increases
making an upward sloping curve.
24Marginal Cost of Pollution Abatement
- The cost to dispose of a unit of pollution in a
nonpolluting way. - Cost increases as the level of pollution
decreases causing a downward sloping curve.
25Optimum Amount of Pollution
- The amount of pollution that is economically most
desirable. - Determined by plotting the curves of marginal
cost of pollution and marginal cost of pollution
abatement and finding the point of intersection.
267
- Describe various approaches to pollution control,
including command and control legislation,
waste-discharge permit policies, emission
reduction credits, and taxation.
27Emission Charge (Taxation)
- A government policy that controls pollution by
charging the polluter for each unit of emissions,
that is, by establishing a tax on pollution. - A popular market-oriented strategy for
controlling pollution, especially in Europe.
28Waste-Discharge Permit Policy
- A government policy that controls pollution by
issuing permits allowing the holder to pollute a
given amount. - Holders are not allowed to produce more emissions
than are sanctioned by their permits.
29Emission Reduction Credits (ERC)
- A waste-charge permit that can be bought and sold
by companies producing emissions. - Companies have a financial incentive to reduce
emissions because they can recover some or all of
their cost of pollution abatement by the sale of
the ERCs that they no longer need.
30Emission Reduction Credits (ERC)
31Command and Control Legislation
- Pollution control laws that work by setting
pollution settings. - One example of command and control legislation is
the Clean Air Act Amendment of 1990.
President Bush Sr. signing the amendment
328
- Explain some of the complexities of the highly
contentious jobs versus the environment issue in
the Pacific Northwest.
33The Northwestern Conflict
- Conflict Fate of thousands of jobs v.s. fate of
old-growth forest and the organisms living in the
forests. - To raise the stakes, the northern spotted owl
lives in the Northwestern forest which is listed
as a threatened species under the Endangered
Species Act.
34 Economic Side
- Thousands of jobs will be lost if the northern
spotted owl habitat were to be set aside. - Rural Pacific Northwest did not have a
diversified economy and the timber industry,
which was already declining, was their main
source of revenue.
35Environmental Side
- The old-growth forest is unlike the other forests
in that it has never been logged because the
trees dont readily grow back, a natural
ecosystem unharmed by humans. - Old-growth forests are a natural treasure to be
protected and cherished.
369
- Define environmental ethics and discuss
distinguishing features of the Western and deep
ecology worldviews.
37Environmental Ethics
- A field of applied ethics that considers the
moral basis of environmental responsibility and
how far the responsibility extends. - Environmental ethics tries to determine how
humans should relate to nature.
38The Western Worldview
- This worldview stresses human dominance over
nature. - Unrestricted use of natural resources, increased
economic growth for an expanding human
population, unlimited consumption of goods and
services to provide material comforts are factors
that make up this worldview.
39The Deep Ecology Worldview
- Based on the works of Norwegian philosopher Arne
Naess. - This worldview stresses spirituality with nature
and advocates reducing human population growth
and replacing technology with simple material
needs.
40Essay Question
- Describe the details pertaining to the
establishment of the worlds first national
parks, including names, locations, and the manner
in which they were established.
41Essay Answer
- Yellowstone National Park was the worlds first
national park it was established in 1872 by
Congress. Yellowstone is located in Idaho,
Montana, and Wyoming, and includes the canyons
and falls of the Yellowstone River. Shortly
after, in 1890, due largely to the efforts of Mr.
John Muir, Yosemite and the Sequoia National
Parks were established. They are both located in
California. In 1906, Congress passed the
Antiquities Act, which authorized the President
to put aside sites that had scientific, historic
or prehistoric significance. By 1916, the US had
13 National Parks and 20 National Monuments.
Today, there are 54 National Parks and 72
National Monuments.
