Demographic transition theory

Pre-industrial stage: High death rates and high birth

rates

Transitional stage: Death rates fall due to rising food

production and better medical care

Industrial stage: Birth rates fall, as women are

employed and as children become less economically

useful in an urban setting

Post-industrial stage: Birth and death rates remain low

and stable

TERM 2

Views on population control

DEFINITION 2

Timothy Cline

Director, Population Connection (formerly Zero

Population Growth)

Access to reproductive health care, including family

planning, is a basic human right.

Douglas Sylva

Senior Fellow, Catholic Family and Human Rights

Institute

For practical and ethical reasons, the worlds limited

development funds could be better spent than in

encouraging further fertility decline.

TERM 3

Affluence and the environment

DEFINITION 3

Poverty can lead to environmental degradation

BUT

Wealth and resource consumption can produce

even more severe and far-reaching environmental

impacts

TERM 4

Lower death rates and lower infant mortality

rates are due in large part to

DEFINITION 4

technological advances, improved sanitation, and

better medical care in developed countries.

TERM 5

In 1798, Thomas Malthus argued

DEFINITION 5

if there was no control over population growth, then

the population would come under check because of

war, disease, and starvation.

When birth rates decline, what happens to

the average age of the population?

The average age of population grows older.

TERM 7

Ehrlich an Holdens 1974 formula that

specifies our impact on the environment is

based on

DEFINITION 7

the interaction among our population, affluence, and

technology.

TERM 8

Demography focuses on

DEFINITION 8

the relationship between population ecology and

population changes.

TERM 9

What does the value S represent when added

to the IPAT model?

DEFINITION 9

Sensitivity of an ecosystem to human factors

TERM 10

Replacement fertility is the total fertility rate

(TFR)

DEFINITION 10

keeps a population stable over time.

Which of the following would be considered a

monoculture?

A 100-acre field, all of which is planted with the same

variety of corn

TERM 17

What has been the trend in crop diversity

over the past century?

DEFINITION 17

We have lost a lot of genetic diversity in plants. In the

U.S., fruit and vegetable crops have decreased in

diversity by 90% in less than one century.

TERM 18

plowing furrows perpendicular to the slope of

land to prevent erosion?

DEFINITION 18

Contour farming

TERM 19

Salinization

DEFINITION 19

occurs when salts build up in the surface of soil as a

result of high evaporation rates in area of low

precipitation.

TERM 20

pest control operates on the principle that the

enemy of ones enemy is ones friend?

DEFINITION 20

Biocontrol

Which of the following is a living museum of

genetic crop diversity?

Seed banks

TERM 22

What marker genes were used in the

construction of these strains and what effect

will this have on the environment where these

plants will be grown?

DEFINITION 22

In the early days of genetic engineering, marker

genes encoded antibiotic resistance and there was

some concern that these genes could be transferred

to disease-causing bacteria. The sequence of events

necessary for such a transfer seems quite unlikely and

there is no evidence that it occurs.

TERM 23

Are genetically modified foods safe to eat?

DEFINITION 23

Since genes make proteins, it might be possible for some

individuals to develop an allergic reaction to the new

proteins found in golden rice. However, enzymes involved

in biochemical synthetic pathways are not known to be

allergenic. In addition, approximately one quarter of the US

corn crop and almost half of the US soybean crop currently

consist of transgenic plants, and there is no reported case

of anyone suffering ill effects from consuming these foods.

TERM 24

introduction of GMF

DEFINITION 24

Given the difficulty in constructing this strain, it seems

unlikely that the entire biosynthetic pathway could be

transferred to another plant or weed. Even if this did

occur, it is difficult to imagine how beta-carotene would

give another plant some sort of selective growth

advantage. If an insect ate beta-carotene, it would most

likely digest it just like any other nutrient.

TERM 25

Will this strain require the use of additional

pesticides or herbicides when compared with

the strains currently grown?

DEFINITION 25

Before this strain of rice can be used, it will have to

be crossed with local strains of rice that have been

adapted to local growing conditions. This will produce

varieties that require no additional herbicides or

pesticides.

When all the trees in a stand are planted at

the same time they are called

even aged.

TERM 32

most cost-efficient but has the greatest

ecological impacts?

DEFINITION 32

Clear-cutting

TERM 33

forest resource management strategy most

closely mimics nature

DEFINITION 33

Ecosystem-based management

TERM 34

What percentage of the worlds land area is

part of a preserve?

DEFINITION 34

TERM 35

Land trusts

DEFINITION 35

are organizations that purchase land to preserve it in

its natural condition.

reported outcome of the Biological Dynamics

of Forest Fragments Project?

Species diversity of most animal groups declines in

fragments

TERM 37

strip mining

DEFINITION 37

To get at shallow, horizontal deposits of minerals

close to the surface

TERM 38

General Mining Act of 1872

DEFINITION 38

U.S. law encourages mineral mining and allows mining

companies to use federally owned land?

TERM 39

Which is the best approach to sustainable

mineral use?

DEFINITION 39

By encouraging recycling of non-renewable resources

TERM 40

Reclaiming a surface mine site includes

DEFINITION 40

removing buildings, filing holes, and replanting

vegetation at a completed site in order to return the

area to pre-mining conditions.
