2. Environmental ethics
Environmental ethics = application of ethical standards to relationships between human and non-human entities
Hard to resolve; depends on the person’s ethical standards
Depends on the person’s domain of ethical concern
Should we conserve resources for future generations?
Is is OK to destroy a forest to create jobs for people?
Should humans drive other species to extinction?
Is it OK for some communities to be exposed to excess pollution?

3. We have expanded our ethical consideration
To include animals, communities, nature

4. Expanding ethical concern
Why have we expanded our ethical concerns?
Economic prosperity: more leisure time, less anxieties
Science: interconnection of all organisms
Non-western cultures often have broader ethical domains
Three perspectives in Western ethics
Anthropocentrism = only humans have rights
Biocentrism = certain living things also have value
Ecocentrism = whole ecological systems have value
Holistic perspective, stresses preserving connections

5. Western ethical expansion

6. History of environmental ethics
People have questioned our relationship with the environment for centuries
Christianity’s attitude towards the environment
Anthropocentric hostility, or
Stewardship?
The Industrial Revolution increased consumption and pollution
People no longer appreciated nature
Transcendentalism = nature is a manifestation of the divine
Ralph Waldo Emerson, Henry David Thoreau

7. The preservation ethic- pristine, unaltered state
Unspoiled nature should be protected for its own inherent value
John Muir ( ) (right, with President Roosevelt at Yosemite National Park) had an ecocentric viewpoint

8. Environmental justice (EJ)
The poor and minorities are exposed to more pollution, hazards, and environmental degradation
75% of toxic waste landfills in the southeastern U.S. are in communities with higher racial minorities

9. Environmental justice and Native Americans
From 1948 to the 1960s, Navajo miners were not warned of radiation risks, nor provided protection by the industry or the U.S. government

10. The conservation ethic
Use natural resources wisely for the greatest good for the most people
Gifford Pinchot ( ) had an anthropocentric viewpoint

11. The land ethic
Healthy ecological systems depend on protecting all parts
Aldo Leopold ( ), believed the land ethic changes the role of people from conquerors of the land to citizens of it

12. Deep ecology, ecofeminism, and justice
Deep ecology = humans are inseparable from nature
Since all living things have equal value, they should be protected
Ecofeminism = male-dominated societies have degraded women and the environment through fear and hate
Female worldview = cooperation
Environmental justice = the fair and equitable treatment of all people regarding environmental issues
Wealthy nations dump hazardous waste in poorer nations with uninformed residents

13. Economics studies how people use resources to provide goods and services in the face of demand
Friction occurs between people’s ethical and economic impulses
Is there a trade-off between economics and the environment?
Generally, environmental protection is good for the economy
Most environmental and economic problems are linked
Root “oikos” gave rise to both ecology and economics

14. Environmental systems support economies
Ecosystem services (Table 2.2) = essential services support the life that makes economic activities possible
*Soil formation *Pollination
*Water purification *Nutrient cycling
*Climate regulation *Waste treatment
Economic activities affect the environment
Deplete natural resources
Produce too much pollution

15. Government intervenes in a market economy
Even in capitalist market economies, governments intervene to:
• Eliminate unfair advantages
• Provide social services
• Provide safety nets
• Manage the commons
• Mitigate pollution

18. Valuing ecosystems goods and services
Our society mistreats the very systems that sustain it
The market ignores/undervalues ecosystem values
Nonmarket values = values not included in the price of a good or service

19. Environmental view of economics
Human economies exist within, and depend on, the environment
Without natural resources, there would be no economies

20. Types of modern economies
Economy = a social system that converts resources into
Goods: manufactured materials that are bought, and
Services: work done for others as a form of business
Subsistence economy = people get their daily needs directly from nature; they do not purchase or trade
Capitalist market economy = buyers and sellers interact to determine prices and production of goods and services
Centrally planned economy = the government determines how to allocate resources
Mixed economy = governments intervene to some extent

21. A steady state economy
As resources became harder to find, economic growth slows and stabilizes (John Stuart Mill, )
We must rethink our assumptions and change our way of economic transactions
This does not mean a lower quality of life
Economies are measured in various ways
Gross Domestic Product (GDP) = total monetary value of final goods and services produced
Does not account for nonmarket values
Pollution increases GDP

22. In the U.S., GDP has risen greatly, but not GPI
GPI: An alternative to the GDP (introduced in 1995 by Non-profit Redefining Progress)
Genuine Progress Indicator (GPI) = differentiates between desirable and undesirable economic activity
Positive contributions (i.e. volunteer work) not paid for with money are added to economic activity
Negative impacts (crime, pollution) are subtracted
In the U.S., GDP has risen greatly, but not GPI

23. Marginal benefit and cost curves
Cost-benefit analysis = the costs of a proposed action are compared to the benefits that result from the action
If benefits > costs: pursue the action
Not all costs and benefits can be identified
Marginal benefit and cost curves determine an “optimal” level of resource use or pollution mitigation

24. Assumption: Costs and benefits are internal
Costs and benefits are experienced by the buyer and seller alone
Do not affect other members of the society
Pricing ignores social, environmental or economic costs
Externalities = costs or benefits involving people other than the buyer or seller
External costs = borne by someone not involved in a transaction
Human health problems
Resource depletion
Hard to account for and eliminate
How do you assign monetary value to illness?
MARKET FAILURE= government did not account for these costs.
Solution= GREEN TAXES charge for external costs

25. Environmental policy and equity
Free Riders = reducing pollution tempts any one person to cheat
Private voluntary efforts are less effective than mandated efforts
External Cost = harmful impacts result from market transaction but are borne by people not involved in the transaction
Environmental policy goals = protect resources against the tragedy of the commons and to promote equity by eliminating free riders and addressing external costs

26. Another economic policy tool
Green taxes = taxes on environmentally harmful activities
Polluter pays principle = the price of a good or service includes all costs, including environmental degradation
Gives companies financial incentives to reduce pollution
But, costs are passed on to consumers

27. Market permitting and incentives
Permit trading = government-created market in permits
Businesses buy, sell, trade these permits
Emissions trading system = government-issued permits for an acceptable amount of pollution and companies buy, sell, or trade these permits with other polluters
Cap-and-trade system = a party that reduces its pollution levels can sell this credit to other parties
Pollution is reduced overall, but does increase around polluting plants
Companies have an economic incentive to reduce emissions

28. Markets can fail
Market failure = markets do not account for the environment’s positive impacts
Markets do not reflect the negative effects of activities on the environment or people (external costs)
Government intervention counters market failure
Laws and regulations
Green taxes = penalize harmful activities
Economic incentives to promote conservation and sustainability

29. Ecolabeling addresses market failures
The market can be used to counter market failure
Create markets in permits
Ecolabeling = tells consumers which brands use sustainable processes
A powerful incentive for businesses to switch to better processes
“Dolphin safe” tuna
Socially responsible investing in sustainable companies

30. Corporations are responding to concerns
Industries, businesses, and corporations can make money by “greening” their operations
Local sustainably oriented businesses are being started
Large corporations are riding the “green wave” of consumer preference for sustainable products
Nike, Gap
Be careful of greenwashing, where consumers are misled into thinking companies are acting sustainably

31. Conclusion
Recent developments have brought economic approaches to bear on environmental protection and conservation
Environmental ethics has expanded people’s ethical considerations
Economic welfare can be enhanced without growth, resulting in economic health and environmental quality

41. Culture and worldview
Our relationship with the environment depends on assessments of costs and benefits
Culture and worldview also affects this relationship
Culture = knowledge, beliefs, values, and learned ways of life shared by a group of people
Worldview = a person’s or group’s beliefs about the meaning, purpose, operation, and essence of the world
Culture and worldview affect our perception of the environment and environmental problems

42. Worldviews differ among people
Different worldviews result in different perceptions
Aborigines saw the negative environmental impacts of the Jabiluka mine
Others saw jobs, income, and energy from the mine

43. Many factors shape worldviews
Religions
Communities
Political ideology
Economics
Individual interests
Vested interest = an individual with strong interests in the outcome of a decision that results in gain or loss for that individual

44. Ethics Ethics = the study of good and bad, right and wrong
Relativists = ethics varies with social context
Universalists = right and wrong remains the same across cultures and situations
Ethical standards = criteria that help differentiate right from wrong
Classical standard = virtue
The golden rule
Utility = something right produces the most benefits for the most people

45. John Rushkin ( ) “little more than laboratoires for the distillation into heaven of venomous smokes and smells”

46. Conventional view of economics
Conventional economics focuses on production and consumption
Ignores the environment
The environment is an external “factor of production”

47. Neoclassical economics
Examines the psychological factors underlying consumer choices
Market prices are explained in terms of consumer preferences
Buyers vs. sellers
The “right” quantities of a product are produced
The market favors equilibrium between supply and demand

48. Classical economics
Competition between people free to pursue their own economic self-interest will benefit society as a whole (Adam Smith, )
The market is guided by an “invisible hand”
This idea is a pillar of free-market thought today
It is also blamed for economic inequality
Laissez-Faire (let people do as they choose)
Rich vs. poor
Critics think that market capitalism should be restricted by government

49. Assumption: Resources are infinite
Economic models treat resources as substitutable and interchangeable
A replacement resource will be found
But, Earth’s resources are limited
Nonrenewable resources can be depleted
Renewable resources can also be depleted
For example, Easter Islanders destroyed their forests

50. Neoclassical economics
Enormous wealth and jobs are generated
Environmental problems are also created
Assumptions of neoclassical economics:
Resources are infinite or substitutable
Costs and benefits are internal
Long-term effects are discounted
Growth is good

52. This lecture will help you understand:
Culture and worldviews
Environmental ethics
Classical and neoclassical economics
Economic growth, economic health, and sustainability
Environmental and ecological economics

53. More “green accounting” indicators
Net Economic Welfare (NEW) = adjusts GDP by adding the value of leisure time, while deducting environmental degradation
Sustainable Economic Welfare (ISEW) = based on income, wealth distribution, resource depletion
These indicators give a more accurate indication of a nation’s welfare
Very controversial, hard to practice. China introduced green accounting 2006 then repressed the 2007 report

54. Other types of economists
Ecological economists = civilizations cannot overcome environmental limitations
Steady state economies should mirror natural ecological systems
Calls for revolution
Environmental economists = unsustainable economies have high population growth and inefficient resource use
Modify neoclassical economics to increase efficiency
Calls for reform
