History of Environmentalism in the US
Naturalist Philosophers (mid 1800s)
•Ralph Waldo Emerson wrote in 1836, “behind nature, throughout nature, spirit is present”
•Nature has intrinsic aesthetic and spiritual values
•Henry David Thoreau published his classic, Walden, in 1854, in which he recounts his life in the woods
Pragmatic Resource Conservation (Mid to late 1800s, early 1900s)
Man and Nature by George Perkins Marshpublished 1864
• Marsh traveled widely and saw environmental damage elsewhere in the world
•His book warned of the ecological consequences of the “conquest” of the frontier—resources are not endless
•Natural forest reserves established in the US in 1873 to protect dwindling timer supplies
•Preservation of nature for future consumption
Pragmatic Resource Conservation
•In 1905, then president Theodore Roosevelt appointed Gifford Pinchot as chief of the Forest Service
•Pinchot argued for forest protection “not because they are beautiful or because they shelter wild creatures of the wilderness, but only to provide homes and jobs for people”
•“…for the greatest good, for the greatest number for the longest time”
Moral and aesthetic nature preservation
•Yellowstone National Park established in 1872 (National Park Service not established until 1916)
•Preservation of nature for nature’s sake
(Mid to late 1800s, early 1900s)
•John Muir, early environmental activist strenuously opposed Pinchot’s policies
John Muir
•Lobbied to create national park system (Formed in 1916, 2 years after his death)
•Fought for the establishment of Yosemite and King’s Canyon National Parks
•“The world, we are told, was made for man. A presumption that is totally unsupported by the facts…”
•Formed Sierra Club in 1892 (http://www.sierraclub.org/)
Interest in environmental issues lagged behind more immediate issues during the early part of the 1900s
By the mid 1900s, there was growing concern about heath and ecological damage caused by pollution
Aldo Leopold
•Founded the field of game management
•His most famous publication A Sand County Almanac was published in 1949, a year after his death
•Chapter called “The Land Ethic” set the foundation for “modern” conservation
•Warned about the consequences of pesticide use (DDT)
Rachael Carson
•Published Silent Spring in 1962
•Book marked the beginning of the modern environmental movement
April 22th, 1970 – First Earth Day20 million people in 2,000 communities marched to demand improved environmental quality
Environmentalism in the 1970s:
Establishment of the Environmental Protection Agency
Clean Air Act
Endangered Species Act
Clean Water Act
Safe Drinking Water Act
Environmentalism in the 1980s:
•Backlash against the environmental movement
•Increased resource use on public lands
•Federal funding for energy conservation and renewable resources cut
•Relaxed federal air and water quality standards
Late 1980s – “Wise-use” movement
Ron Arnold major proponent, wrote “The Wise-use Agenda”
•Replace National Park Service with privately operated parks
•Remove restrictions on wetland development
•Cut all remaining old growth forests and replace with tree farms
•Open all national parks, wilderness areas, wildlife refuges, to off-road vehicles, commercial development, mining, and drilling for oil
At the same time (1980s), visible environmental problems pushed environmental issues to the forefront
Exxon Valdez oil spill
Hypodermic needles and other toxic waste washing up on beaches in NY and NJ
At the same time (1980s), visible environmental problems pushed environmental issues to the forefront
1983 EPA and National Academy of Sciences Report warns of environmental problems associated with global warming
Thinning ozone layer over Antarctica
Global environmental citizenship - 1990s
1997 Kyoto ProtocolNations pledged to reduce emissions US signed but did not ratify the protocol - the accord's tough requirements would be too costly to the U.S. economy.
1992 Earth Summit in Rio de Janeiro172 Governments participatedFocus on Climate Change and Biological Diversity
Global environmental citizenship1990s to present
•Clinton administration protected more land as national monuments in lower 48 states than did any other administration
•Increase awareness by the general public regarding issues of biodiversity, invasive species, global change, etc.
•UN names 2003 as the International Year of Freshwater
2000-present: Current Administration often comes under attack from Environmental Groups
•Favors increased use of resources on Federal lands (e.g., “Healthy Forest” initiative)
•Revisions to the Clean Air Act that allow increased pollution
•VP Cheney: Conservation may be a sign of personal virtue, but it is not a sufficient basis for a sound, comprehensive energy policy.
Points to know:
1. Name 5 disciplines that environmental science encompasses.
2. Know the major environmental concerns of the 6 major regions of North America.
3. How do environmental issues become a global concern?
4. For each person, classify their environmental view as “nature”, “conservation” or “consumption”:
Ron Arnold Ralph Waldo Emerson John Muir
Rachael Carson Aldo Leopold Gifford Pinchot
Dick Cheney George Perkins Marsh Henry David Thoreau
5. Know the environmental issues (generally, and at least 2 specifically) that occurred in:
1970’s 1980’s 1990’s 2000-present
Environmental Ethics
Lecture Objectives:
1. Learn three theories of moral responsibility to the environment
2. Learn three prevailing environmental attitudes
3. Explore how individuals, governments and corporations approach environmental ethics
Ethics - Seeks to define fundamentally what is right and what is wrong, regardless of cultural differences.
Morals - - Reflect predominate feelings of a culture about ethical issues.
Ethics and Morals
Environmental ethics - Topic of applied ethics that examines the moral basis of environmental responsibility
Three primary theories of moral responsibility regarding the environment
Anthropocentric: : (Human centered)
Responsibility derived from human interests
Only humans are morally significant
Preservation for future consumption
Three primary theories of moral responsibility regarding the environment
Biocentric::
Life-centered rather than human centered
All life forms have a right to exist
Animal Rights
Three primary theories of moral responsibility regarding the environment
Ecocentric::
Environment deserves direct moral consideration
The environment has an inherent value
Advocated by Aldo Leopold
Ecocentric View“A thing is right when it tends to preserve the integrity,
stability, and beauty of the biotic community. It is wrong when it tends otherwise….We abuse land because we regard it as a community belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect.”
- Aldo Leopold
Environmental Attitudes
• Developmental Ethic
• Preservation Ethic
• Conservation Ethic
Developmental Ethic
• Based on individualism.
• Assumes humans are, and should be, masters of nature.– All resources exist solely for human benefit.
• Reinforced by work ethic.– Humans should always be busy and create
“progress.”
Preservation Ethic
• Nature has intrinsic value apart from human appropriation.
• Reasons range from aesthetic to scientific.– Animal Rights—all creatures have a right to
live, regardless of social or economic costs.– Humans dependent on environment.
• Preserve nature for future generations.
Conservation Ethic
• Extends rational consideration to entire earth.• Works toward a balance between resource use and
availability.• Stresses finding a balance between total
development and absolute preservation.– Rapid, uncontrolled growth is self-defeating in the long
run.
When raw materials are processed, some waste is inevitable.
Corporations - legal
entities designed to
operate at a profit.
Corporate Environmental Ethics
Many consider manufacturing waste unethical, while corporations may see it as one factor determining profitability.
The cost of controlling waste can be very important in determining a company’s profit margin.
28 August 2003
EPA softens rules to allow more emissionsIndustries say change will aid system upgrades
Profit margin determines expansion.
More expansion leads to more production and more wastes.
Corporate Environmental EthicsPracticing an environmental ethic should not interfere with corporate responsibilities.It makes little sense to preserve the environment if preservation causes economic collapse
Nor does it make sense to maintain industrial productivity at the cost of breathable air, clean water, wildlife, parks, and wilderness.
Compromise is possible
NIMBY - Not In My Back Yard
Waste generation is directly correlated with per capita income, but few toxic waste sites are located in affluent suburbs.
Individual Environmental EthicsRecognition of individual responsibility must lead to changes in individual behavior.
Recent opinion polls indicate that Americans think environmental problems often have a quick technological fix.
Many want a cleaner environment, but do not want to make the necessary lifestyle changes
If everyone on Earth consumed as much oil as the average American, the world’s known reserves would be gone in a decade
Consumption
Ecologist Paul Ehrlich argues the American lifestyle is driving the global ecosystem to the brink of collapse.
Bet between Simon and Erhlich (1980):
Consumption
Economist Julian Simon argued human ingenuity, not resources, limits economic growth and lifestyles.
Erhlich – Consumption of resources would drive prices up
Simon – Technology would replace any potential shortages and prices would fall
Result of bet between Simon and Erhlich (1990)
Metal 1980 price 1990 price(1980 dollars) (1980 dollars)
Copper (195.56 lbs.) $200 $163 Chrome (51.28 lbs.) $200 $120 Nickel (63.52 lbs.) $200 $193
Tin (229.1 lbs.) $200 $56 Tungsten (13.64 lbs.) $200 $86
Erhlich – prices fell because of lower demand
Simon – prices fell because of new materials (e.g., plastics)
Global Environmental Ethics
Ecological degradation in any nation inevitably impinges quality of life in others.
