OVERPOPULATION

World Population Clock(Shows how quickly the
world population is increasing)

  • Although people no longer talk about a
    catastrophic population bomb, world population
    continues to grow. Unfortunately, the most
    affected countries are also the ones least able
    to support more people.

  • Nearly three-fifths of the 4.8 billion people in
    developing countries lack basic sanitation,
    almost a third have no access to clean water, a
    quarter lack adequate housing, and a fifth lack
    access to modern health services

6
Drastic overpopulation causes economic problems
and creates slums
7
  • The world's population is expected to reach 8
    billion by the year 2020.
  • Already, more than half the world's population--
    over 2.7 billion people--live within 60 miles
    (100 km) of a coastline

  • Rapid urbanization, especially in developing
    countries, will lead to more coastal
    megacities--cities with 10 million or more people
    .
  • As coastal zones become more densely populated,
    coastal water quality will suffer, wildlife will
    be displaced, and shorelines will erode .

10
Overpopulation causes environmental problems like
garbage. Or a source of food for the poor.
11
  • With only 4.6 percent of world population,
    Americans use about one-third of the world's
    processed mineral resources, and about one-fourth
    of the world's non-renewable energy sources, like
    oil and coal .

12
More People More Energy MORE POLUTION
13
Lets have a Debate
  • Statement of the Problem Should governments
    limit the number of children a woman can have in
    her lifetime in order to solve the problem of
    overpopulation?

14
Student Arguments For Govt. Restrictions
  • Overpopulation needs to be dealt with
  • Proven successful
  • Limits population
  • Helps less developed countries become
    self-efficient
  • Improves standards of life for citizens by
    forcibly moving them along in the demographic
    transition

15
Student Arguments Against Govt. Restrictions
  • Human Rights issues are infringed upon
  • Gender imbalance occurs
  • Raises the number of abandoned and orphaned
    children.
  • Un-safe measures begin to take place (abortions,
    unsafe contraceptives, etc...)
  • Makes more thorough ways like contraceptive
    education less available

28
