3. Environmental Issues, Their Causes, and Sustainability
G. Tyler Miller’s
Living in the Environment
13th Edition
Chapter 1
Dr. Richard Clements
Chattanooga State Technical Community College
Modified by Charlotte Kirkpatrick 2005

4. Key Concepts Growth and Sustainability Resources and Resource Use
Pollution
Causes of Environmental Problems

5. Living More Sustainably
Ecology: Studies relationships
between living organisms and their
environment.
Environmental Science: interdisciplinary
science that helps us to understand how the earth
works, how we affect the earth, and how to deal with
environmental problems.
Refer to Spotlight on p. 3

6. Sustainability
Sustainable Society: satisfies the basic needs of its people for food, clean water, clean air, and shelter into the indefinite future without depleting natural resources.
Living sustainably: Living off the earth’s natural income and not depleting the earth’s natural capital.

7. Solar and Earth Capital
Know this diagram you will reference it several times this year (p. 92)

8. Warm Up #2 1. What does it mean to live sustainably?
2. Are we living off of earth capital or income?
3. Is the human population still growing exponentially?
4. With a growth rate of 2.5% what is the doubling time?

9. Population Growth Linear Growth Exponential Growth
Fig. 1-2 p. 4
Doubling Time/ Rule of 70
Doubling time (years) = 70/% growth rate
Ex. 70/1.28=54.7 years
See spotlight p. 5

10. World Population
Fig. 1-1 p. 2

11. Economic Growth Indicators
Gross National Product (GNP)
[also referred to as Gross National Income (GNI)]
Gross Domestic Product (GDP)
Gross World Product (GWP)
Per Capita GNP
(also referred as per capita GNI)

12. GNP vs GDP
GNP(GNI): Market value in current $ of all goods and services produced by an economy, inside and outside that country, for final use during a year.
GDP: Same as GNP except it only includes goods and services produced within a country

13. Purchasing Power Parity
PPP: Purchasing Power Parity is another economic measure that more accurately compares standards among countries.
GNI PPP: The market value of a countries GNI in terms of what it would buy in the U.S.

14. Per Capita GNI (GNP)
Per capita GNI: total GNI divided by the total population at midyear.
Provides the average slice of the economic pie per person.
Per capita GNI PPP: the GNI PPP divided by the total population midyear. Again a better way to compare people’s econmic welfare among countries.

15. Wealth Gap

16. Economic Development
Economic Development: Improvement of living standards by economic growth
Developed Countries: Highly industrialized with a high GNI PPP (over $10,750 per year in most cases)
Developing Countries: some middle income, moderately developed countries with GNI PPP of $2701- $ Others are low income with GNI PPP of <$2701/year
[ See fig. 1-3 p. 5]

17. Developed vs. Developing Countries
Developed Countries :
total population of 1.2 billion people
have 85% of world’s wealth and income
use 88% of worlds resources and
generate 75% of its pollution and waste
Developing Countries:
total population of 5 billion people
have 15% world’s wealth and income
use 12% of its resources
generate 25% of its pollution and waste

18. Warm Up #3 What is the difference between GNP and GDP?
Why is per capita GNP a better economic measure than GNP alone?
What is the impact seen on the world by Developed Countries vs. Developing Countries.
In your opinion, is globalization a good thing?

19. MDC’s(developed) vs. LDC’s(developing)

20. Globalization
Globalization: global social, economic, and environmental change leading to increasingly integrated world.

21. Indicators of Globalization
Economic:
Increase in global economy
Increase in international trade of goods and services
Increase in the number of transnational corporations
operating in 3 or more countries
Information and Communication
Increase in number of people with internet access
(1 in 11 world wide as of 2002)

22. Indicators of Globalization (cont.)
Environmental Effects
increase in the number of infectious organisms transported across international borders
increase in pollutants transferred around the globe leading to widespread ocean pollution, ozone depletion, and climate change

23. Resources Perpetual Renewable: (potentially renewable) Non-renewable:
On a human timescale
is continuously renewed
Renewable: (potentially renewable)
Replenished on a human
time scale if not used up
faster than replaced
Non-renewable:
On a human timescale
they are not renewable,
fixed amounts
Fig. 1-6 p. 9

24. Renewable Resources Sustainable Yield: the highest rate at
Which a renewable resource can be used indefinitely
Without reducing its available supply
Environmental Degradation: When we
exceed a resource’s natural replacement rate, the
available supply begins to shrink
Tragedy of the Commons: overuse of
common property or free-access resources
Refer to Connections, p. 11

25. Non-Renewable Resources
Energy Resources
Metallic Resources
Economic Depletion
Fig. 1-7 p. 10
Non-Metallic Resources

26. Extending nonrenewable supplies
Reuse:Using a product in the same form over and over again
Recycle: collecting and reprocessing a
product

27. Ecological Footprint: amount of land needed to produce the resources needed by an average person in a country
Fig. 1-8 p. 10

28. Pollution What is pollution? Effects of Pollution
Any addition to air, water, soil, or food that threatens
the health, survival, or activities of humans or other living
organisms
Effects of Pollution
Disruption of life-support systems for humans and
other species.
Damage to wildlife, human health and property.
Nuisances such as noise and unpleasant smells,
tastes, and sights.

29. Point: Where pollutants come from single, identifiable sources
Sources of Pollution
Point: Where pollutants come from single, identifiable sources
Nonpoint: Where pollutants come from
dispersed and difficult to identify sources
Which would be easier to control and clean
up after?

30. Dealing With Pollution
Prevention (Input Control)
Reduces or eliminates the production of the pollutants
Cleanup (Output Control)
Cleaning up of pollutants after they have been produced.
3 problems with cleanup:
1. It is only a bandage
2. Often removes pollutant from one part of the
environment and cause pollution in another.
3. Too costly

31. Environmental and Resource Problems

33. Environmental Interactions

34. Environmental Worldviews
Planetary Management:
Humans manage the earth mostly for their needs
We are in charge of nature
There is always more
All economic growth is good
Success is determined on how well we understand,
manage and control the earth’slife support systems for
our benefit
Environmental Wisdom:
Complete opposition of planetary management
