World population change
popgraph.jpg (92405 bytes)

Over the years population has changed dramatically. In 1540 the population stood at 300 million. In 1750 the population was estimated at 791 million. In 1900 it had again grown to 1.7 billion. By 1950 it had reached 2.5 billion. More than a 50 % increase in the last 50 years. Between 1950 and 2000 the population grew to 6.2 billion. It is predicted in the next 50 years it will double again to almost 12 .5 billion. Problems which arise due to the rapid increase of population are that of over- crowding, resulting in shortages of food and water, not enough health care and fewer means of Education. It also decreases our natural habitat because we destroy woodlands, rain forests, forests and areas of natural beauty; as we need the space to build houses, schools and Health Centres. This is the concept of OVER POPULATION.

In 1999 D6B was official, the day of 6 billion people, and for the near future Global population shows no sign of slowing down.
Most of the population growth is found in LEDCs (Less Economically Developed Countries) such as China and India.
Africa’s population growth is large despite the Aids virus lowering life expectancy.
Most rich countries have stable populations (e.g. France and the USA) while some others have declining populations (e.g. Russia).
 

Activities

a) Describe the patterns on the graph above for both MEDCs (Industrialised nations) and LEDCs (developing regions) on this exercise or on this slightly easier exercise

b) Look at the world Population clock using this link - includes pop clock , calculate how much the world population increases in 1 minute. Then in an hour!

c) Revise population with BBC bytesize, then take a test bite.

d) What consequences are there for the people living in countries with rapid population growth? Make a list of all of the ways that lives could be affected.

e) If you were president of a LEDC what would you do to combat these problems?

f) Matching exercises on Population 1 and Population 2
