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.
- Is LR Vanderkam an optimist or a pessimist?
- 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:
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:
-
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.

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

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):

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 !

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

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/
-
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.
