between living organisms and their
science that helps us to understand how the earth
works, how we affect the earth, and how to deal with
Refer to Spotlight on p. 3
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.
Know this diagram you will reference it several times this year (p. 92)
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?
Fig. 1-2 p. 4
Doubling time (years) = 70/% growth rate
Ex. 70/1.28=54.7 years
See spotlight p. 5

[also referred to as Gross National Income (GNI)]
(also referred as per capita GNI)
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
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.
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.
[ See fig. 1-3 p. 5]
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
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
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?
Globalization: global social, economic, and environmental change leading to increasingly integrated world.
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 innumber of people with internet access
(1 in 11 world wide as of 2002)
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
On a human timescale
is continuously renewed
Replenished on a human
time scale if not used up
faster than replaced
On a human timescale
they are not renewable,

Which a renewable resource can be used indefinitely
Without reducing its available supply
exceed a resource’s natural replacement rate, the
available supply begins to shrink
common property or free-access resources
Refer to Connections, p. 11
Fig. 1-7 p. 10
Reuse:Using a product in the same form over and over again
Fig. 1-8 p. 10
Any addition to air, water, soil, or food that threatens
the health, survival, or activities of humans or other living
Disruption of life-support systems for humans and
Damage to wildlife, human health and property.
Nuisances such as noise and unpleasant smells,
tastes, and sights.
Point: Where pollutants come from single, identifiable sources
dispersed and difficult to identify sources
Which would be easier to control and clean
Reduces or eliminates the production of the pollutants
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

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
