• There can be no peace in the world so long as a
  large proportion of the population lack the
  necessities of life and believe that a change of
  the political and economic system will make them
  available. World peace must be based on world
  plenty. John B. Orr
• "Unlike plagues of the dark ages or contemporary
  diseases we do not understand, the modern plague
  of overpopulation is soluble by means we have
  discovered and with resources we possess. What is
  lacking is not sufficient knowledge of the
  solution but universal consciousness of the
  gravity of the problem and education of the
  billions who are its victim."
• --Martin Luther King, Jr., civil rights leader
  and Nobel laureate

• "What becomes of the surplus of human life? It is
  either, 1st. destroyed by infanticide, as among
  the Chinese and Lacedemonians or 2d. it is
  stifled or starved, as among other nations whose
  population is commensurate to its food or 3d. it
  is consumed by wars and endemic diseases or 4th.
  it overflows, by emigration, to places where a
  surplus of food is attainable."
• --James Madison, 1791, U.S. President
• "The key problem facing humanity in the coming
  century is how to bring a better quality of life
  -- for 8 billion or more people -- without
  wrecking the environment entirely in the
  attempt."
• --Edward O. Wilson, scientist, Pulitzer prize
  winning author and father of biodiversity
• "Once it was necessary that the people should
  multiply and be fruitful if the race was to
  survive. But now to preserve the race it is
  necessary that people hold back the power of
  propagation."
• --Helen Keller, world-renowned deaf and blind
  author and lecturer

Different countries, different trends

• IPxAxT
• Impact is proportional to population, affluence
  and technology
• Environmental Impact can be attributed to
  population size, affluence of lifestyle and
  stewardship
• Rich nations negative environmental impact due
  to affluence, not numbers
• Poor nations negative environmental impact due
  to numbers not affluence

Calculating Population Growth

• Increase in population
• Birth rate-death rate immigrants-emigrants
• Increase/original x 100 percent growth rate
• Note birth rates and death rates are often given
  per 1000 people, so they may need to be converted
  first before adding and subtracting immigrants
  and then by dividing by original population.
• Example If a city of population 10,000
  experiences a birth rate of 10, a death rate of
  4, 10 immigrants, and 30 emigrants in the course
  of a year, what is its net annual percentage
  growth rate?
• answer 0.40

Calculating Doubling Time

• The time it takes for a country to double its
  population
• 70/percent growth rate
• Examples if a population is growing at an annual
  rate of .5, the number of years it will take for
  that population to double can be found by
  dividing 70 by .5, or DT 70/.5 140 years.
• Calculate the doubling time for a population
  growing at 2.5.
• Answer 70/2.5 28 years
• Why the rule of 70?
