Population Control
Introduction

   Some have suggested that population growth
    is a spur to the economy, which spurs
    solutions to the problem caused by
    population
   Some say that the world’s population is out of
    control
Foragers and Population Control

   Economic levels
       Hunting and gathering (foraging)
       Pastoralism (herding)
       Horticulture (gardening)
       Agriculture (farming)
       Industry (Mass production)
   Each has its own relationship to population,
    but after people domesticated plants, the
    relations between economy and population
    changed
Hunters & Gatherers

   Kept very low population levels, usually less
    than 1 person per square mile
   Overhunting and overgathering are key
    issues
   You eat what you produce, almost daily
   Extraordinarily sensitive to the environment
   Ranger of techniques to control population:
       Birth spacing
       Nomadism
       Social organization restrictions on marriage
        partners
       Sexual division of labor and male absence
       infanticide
   Difficult to keep population levels low; high
    emotional costs
   Pay me now or pay me later attitude
   Original affluent society
   Many misconceptions
   If population is held in check, quality of life is
    high
   Little need to develop surpluses, that is extra
    food can be stored and used later
Surpluses

   Controls can be lifted on population, but work
    begins to intensify, causing substantial
    change to the culture
   Someone must care for animals & gardens
    more people involved, less labor intensive it
    is & the more leisure time there is
   Surpluses allow expansion of the economic
    base
   Specialization of labor
   Social stratification
   Increased energy needs
   Overspecialization risks
   Environmental degradation
   Weighs factors of population, intensification
    of labor, and quality of life over time
   Population increase decline in quality of
    life intensification of production
    population increase
