list 3 problems with cornucopian argument regarding population growth not being a problem

Ethical - increasing our carrying capacity can harm other species
Economical - increasing population is correlated to poorer populations
Technical - can not reinvent every resources when they run out

T-
S-

I- impact on environment
P-population - need space/resources
A-affluence- greater per capital resource use
T- technology- increase exploitation (resources)
S-sensitivity- how sensitive an area is to human pressure

Having many individual sion young age groups results in :
- _____ reproduction
-________ population growth

High
Rapid

What would you expect if there are many individuals in young age groups?

High growth rate
Increased reproduction
Strain on resources

Naturally occurring sex ratios for mans slightly favour ____

Males

Whether a population grows, shrinks, or remains
stable depends on:

Rate of birth/death
Immigration
Emigration

_________= number of births per 1000 individuals

Crude birth rate

_______= number of deaths per 1000 individuals

Crude death rate

_____ might be used as a measure of how “healthy” a population is

Crude death rate

_______ = average number of children born per female member of a population during her lifetime Influences population growth

Total fertility rate (TFR)

_______= The TFR (total fertility rate) that keeps the size of a population stable

Replacement fertility

Name 3 factors that reduce TFR (total fertility rate)

Urbanization Social security Empowerment & contraception

How does urbanization reduce TFR ?

children are not needed to work land but go to school = costs more

How does social security reduce TFR ?

Elderly parents need Fewer kids to support them

How does greater education of women reduce TFR ?

Women are pursuing studies for an extended amount of time, delaying getting married, less emphasis on bearing children

How does empowerment and access to modern contraception reduce TFR ?

Women are able to control when they want to reproduce if they want to. Fewer unwanted pregnancies

Poorer societies have ____ growth rates than wealthier societies

Higher

About ______ living on less than $1.25/day

1 billion

The richest 20% use ____ % of the worlds resources

90%

__________goals = by 2015 achieve goals for sustainable development

Millennium development

Name 3 ways the population will stop rising

Disease Social conflict Governmental intervention Demographic transitions

What has accounted for the majority of the world’s population growth in recent years? a) Women are having more babies b) Death rates have dropped due to technology, medicine, and food c) More women are using contraceptives d) Nothing, the population has dropped in recent years

A developing country has the population growth rate 2% per year (almost twice the global average). If the growth rate was sustained, how long would it take to get from today’s 10 mln to: _20_ mln and _40_ mln, respectively: Hint: P (n) = (1+g)n *P(0) A) 50yrs and 150 yr B) 50 yrs and 100yrs C) 35 yrs and 105 yrs D) 35 yrs and 70 yrs

Order TFR from the highest to the lowest (current unless indicated otherwise): a) Egypt > Canada > Canada (17th century) > China b) Egypt > Canada > China > Canada (17th century) c) Egypt > Canada (17th century) > Canada > China d) Canada (17th century) > Egypt > Canada > China

Areas that lack significant numbers of people, and have a Low population density are… a) No longer available b) Best able to support higher densities of people c) Sensitive areas least able to support high densities of people d) Located around tropical and grassland areas

Describe the relationship between growth rates and population size. a) Falling growth rates automatically mean a smaller population b) Falling growth rates automatically mean a larger population c) Falling growth rates means we no longer have a population problem d) Falling growth rates does not mean a smaller population, but that rates of increase are slowing
