SOLUTIONS: INFLUENCING POPULATION SIZESection 10-3
CAN THE WORLD PROVIDE AN ADEQUATE STANDARD OF LIVING FOR 2.5 BILLION MORE PEOPLE WITHOUT CAUSING WIDESPREAD ENVIRONMENTAL DAMAGE???
IS THE PLANET ALREADY OVERPOPULATED???
WHAT TYPES OF MEASURES SHOULD BE TAKEN TO CONTROL POPULATION SIZE?
SHOULD WE ENCOURAGE POPULATION GROWTH?
REGULATE POPULATION SIZE?
Declining environmental issues
1 out of 6 people do not get necessities to survive
Higher death rate
People are most valuable resource

YES NO
DEMOGRAPHIC TRANSITION
Demographic transition– as countries become industrialized, first their death rates and then their birth rates decline
Transition takes place in 4 stages: 4 Stages
Preindustrial – when there is little population growth due to harsh living conditions High birth rate (high infant mortality rate) High death rate Little population growth
Transitional – Industrialization begins, food production rises, and health care improves High birth rate Lower death rate Populations increase
DEMOGRAPHIC TRANSITION
4 Stages continued… Industrial - Industrialization, medical advances,
& modernization become widespread Low birth rate (approaches death rate) Low death rate Population growth is slower
Postindustrial - birth rate declines further, equaling the death rate; reaching zero population growth Population size may decrease
DEMOGRAPHIC TRANSITION
Demographic trap - countries that cannot rise above the transition level for different reasons
Shortage of skilled workers Lack of financial capital Pay back debts Not receiving money from
developed countries
FAMILY PLANNING Geared toward married women Increase education & clinical services
Limiting # of kids Spacing of kids Contraception (use is up to 51% from 10% in the
60s) Health care
Thailand & Iran decreased TFR (total fertility rate) 6 to 3.1!
Reduced # of abortions (legal & illegal) Future
Include teens & unmarried women Educate men to take responsibility & importance
of fewer children
FAMILY PLANNING
Iran Used FP = TFR 7 to
2.5 Pop. Growth cut in
½ To get a marriage
license – need to take a contraception class
Increase female literacy & school enrollment
FAMILY PLANNING
Women have fewer kids if: Educated Paying job outside the home Rights not suppressed
Solution = gender equality!!
India Implemented FP but not
going well…why? Emphasis on having males Need kids to support in old
age Poverty, govt. inefficiency,
etc.
FAMILY PLANNING
China TFR 5.7 to 1.7 Why? Postpone marriage Benefits for promising to have 1 child Free sterilization, contraception, abortions Other alternative = mass starvation
WHAT CAN WE DO?
Increase FP & reproductive health care Create national population policies Improve health care Improve status of women (education & jobs) Involve men in child rearing & FP Reduce poverty Reduce consumption habits
