Population Crisis– Fact or Fantasy?

Consider this statement:

"Forget the Year-2000 (Y2K) computer virus - it's the Y6B population problem that has demographers worried. "
L.R.Vanderkam, The Washington Times 13thJuly  1999.

  1. Is LR Vanderkam an optimist or a pessimist?
  2. What is the opposite point of view?

The Big Enquiry Question
Is population growth out of control & does it matter?


The purpose of the enquiry is to:

  • develop an awareness and understanding of the nature of and reasons for population growth.

  • develop and understanding of the issues arising from continued population growth

  • develop an awareness of different views and opinions on the solutions to the issues raised by continued population growth.

  • develop ICT and/or data handling and analysis skills.

 

Your task: is to create a campaigning leaflet for either [or preferably both]

  • the optimists

  • the pessimists

You need to carefully consider the words and the statistics that you publish.

Use these little questions as a guide to the weblinks:

  1. At what rate has the population of the planet grown?

    Plot the World Population estimates onto a graph (using Excel if possible). Check your answer against the figure at http://www.gcrio.org/CONSEQUENCES/summer95/population.html

    Identify the type of growth curve shown.

  2. What is the estimate of today's population?  Visit site http://metalab.unc.edu/lunarbin/worldpop

 

Time

Population

Growth

Now (T1)

 

 

T2: 6 minutes after T1

 

 

Write down the current estimate (T1).

Be careful to time six minutes from now and then repeat!

Calculate the population change (number not percentage) over 6 minutes and then use this to calculate the possible change (at current rates):

Time scale

Population change

over 1 hour

 

over 1 day

 

over 1 week

 

over 1 month

 

over 1 year

 

How much has the world's population increased since you were born?

Time

Population

% Growth

Now (T2)

 

---------------

Your birth date (Date: ) T1

 

 

Difference

 

 

Enter the current population estimate (T2) and the estimate on your birth date (T1). Subtract T1 from T2 to calculate the difference. Now calculate the percentage increase !

  1. At this rate when will the population reach the following size: add approximate figures from the graph on site: 

  2. http://www.un.org/popin/ 

 

 

High Fertility

Medium Fertility

Low Fertility

7 Billion

 

 

 

8 Billion

 

 

 

9 Billion

 

 

 

10 Billion

 

 

 

 

  1. Is population growth evenly distributed across the planet?

    Using Table 3 from the site above:

    a) What is the % growth Rate for the world population between 1998 & 2050

    b) Compare the Developed and Less Developed Regions populations - what do you see?

    c) Plot the % change per continent in descending order and/or map onto world basemap.

    d) Describe your findings with help from http://www.un.org/popin/

  2. Is population growth sustainable or should we limit population growth?

You might like to read : http://www.studentbmj.com/back_issues/1199/editorials/395.html or http://www.siue.edu/~rblain/worldpop.htm to give you further evidence of contrasting views.
