1. Why?
Overpopulation
(too many people)
The answer?

2. What would happen if the no
What would happen if the no. of pupils in this classroom doubled but nothing else changed?

3. What happens next?
What happens now?
What are the scenarios?

4. IS THE WORLD’S POPULATION GROWTH SUSTAINABLE?
BIG JUICY QUESTION.
IS THE WORLD’S POPULATION GROWTH SUSTAINABLE?

5. What is the current situation?
Currently the world’s population is rising at 3 people per second – that’s about:
per day,
or 1.8 million per week,
Or 7.2 million per month
Or 87 million per year!!!
What will happen to the planet as a result?

6. THE BALANCE BETWEEN POPULATION & RESOURCES

9. Overpopulation: Too many people for a country or area to support with the resources available.

10. The global effects of overpopulation

11. FAMINE: As the world’s population increases, we will struggle to produce enough food to feed them all.

12. DROUGHT: People’s need for freshwater, and the amount that we waste, will lead to severe water shortages.

13. POLLUTION: The increase in cars, factories and the increased use of electricity will lead to worse pollution.

14. WAR: The desire for land, food, resources and space will lead to war and violence between countries.

15. POVERTY AND HOMELESSNESS: Lack of jobs and lack of homes will result in increased poverty and homelessness.

16. UNEMPLOYMENT: A lack of jobs for the increasing population may result in huge numbers without a job.

18. 05 (b) Study Figure 6 which shows birth rates, death rates and total population for Malaysia
from 1960 to (b) To what extent does Malaysia fit the demographic transition model for the time period shown in Figure 6?

19. 5 (a) Distinguish between natural and migration population change. (3)

20. 6 (b) (ii) Comment on issues arising from the exporting of food from poorer countries to richer countries. (7)

21. deforestation of areas for food
6 (b) (ii) Comment on issues arising from the exporting of food from poorer countries to richer countries. (7)
distance involved in transport, often by air and the impact on the environment – food miles, carbon footprint and global warming
deforestation of areas for food
use of chemicals in the form of pesticides and fertilisers.
Role of TNCs, waste, reliance on trade links,
. There are economic issues such as the removal of areas of land
from food production for commercial produce and the benefits with
regard to development that come with this versus the lost food production.
There may be knock-on effects regarding demand for water and irrigation.

22. 5 (a) Distinguish between birth rate and fertility rate. (4)

24. POPULATION AND RESOURCES - THE THEORIES
The Club Of Rome
Julian Simon
Ester Boserup
Thomas Malthus

25. THOMAS MALTHUS
Thomas Malthus (1766 – 1834)

26. MALTHUS 1798:
He said:
In the absence of any checks, population will grow geometrically (2,4,8,16). It will double in 25 years.
Even in best conditions farming increases arithmetically (1,2,3,4)
So population outstrips food production.
The result - natural checks will reduce population - famine, war, disease. This will increase death rate and reduce population.
Malthus was a pessimist.

27. ESTER BOSERUP
Ester Boserup ( )

28. BOSERUP: 1965
She said:
Boserup was an optimist. She believed that 'necessity is the mother of invention'.

29. JULIAN SIMON
optimistic or Cornucopian view of population and resources ('Boomster).
he argues, increasing wealth and technology make more resources available.
Simon argues that population is the solution to resource scarcities and environmental problems, since people and markets innovate.

30. THE CLUB OF ROME
First came to public attention with 1972 'Limits of Growth' report.
The book echoes some of the predictions and concerns of Malthus.
5 variables were modelled: world population, industrialization, pollution, food production and resource depletion. These grow exponentially, however technology needed to increase the availability of resources grew only linearly.
Became known as a 'doomsday prophecy'.
Founded 1968

32. BALLOON DEBATE: POPULATION AND RESOURCES
Should I stay or should I go?

33. Your task Your team has 15 minutes or so to do the following:
Elect a spokesperson to go in the balloon. This person needs to be eloquent, persuasive and ‘know their stuff’.
You need to prepare 4 short speeches, each one designed to PERSUADE ME that your opinion is the one that counts and therefore saving you from being hurled out of the balloon.
You need to think of any questions that you would like to ask other groups to scupper their argument and increase their chances of being ejected from the balloon.

34. Conclusion: having listened to all of the evidence, what is your opinion of the population and resources debate? Are you a Malthusian, or a Boserupian? Explain your answer with clear reasons based on the arguments heard.
