Population questions and model answers
1. Explain how the physical factors shown in figure 3 (rainforest, desert.
Mountains & arctic) cause low population density.
(6 marks)
Mountainous areas like the Himalayas are very cold in winter -25°C and
cool in summer 14°C so it has a short growing season and can't support
farming. The slopes are steep which leads to landslides and poor soil
which makes it difficult to farm. The soil is also poor in the Amazon
rainforest as heavy rainfall, 2000mm per year causes the nutrients to be
washed away. Without food production, people can't survive. The
humidity and heat also make it difficult to live comfortably. Desert
areas like the Sahara are also difficult to live in because of high
temperatures 35°C and lack of water for farming.
2. Describe the problems that may be caused by high levels of
population growth in LEDCs.
(6 marks)
Over population leads to food shortages like in Ethiopia which can lead
to the over use of soil and deforestation. In Calcutta there is not
enough housing and not enough jobs to go round which has lead to the
development of shanty towns. These have open sewers and there is
often not enough food or water to go round so diseases like typhoid and
malaria spread quickly which causes the infant mortality to rise so
couples are more likely to have larger families to look after them in old
age. More children would mean fewer spaces in schools so many would
be uneducated which means they wouldn't be able to get well paid jobs
and they also might not know how to use contraception correctly so
again population would increase.
3. Explain why the population grows faster in some countries than
(4 marks)
Some religions believe that contraception and abortions are wrong which
would mean more children are being born. A lack of education in some
countries means that people might not know how to use contraception
correctly or be able to read the instructions. Lack of education would
also mean that they are less likely to have well paid jobs so they would
get no pension. This would mean that they would want large families to
work on the land and to look after them in old age. Higher infant
mortality rates would also mean that families would have more children.

Here's a taster:

Many LEDCs have a high population growth rate. Using one or more
examples you have studies, describe the measures that have been
introduced to control population growth and explain why they were
needed. (9 marks)
In the 1980s China's population was over 1000 million so the
government introduced the very strict `one child policy' which says that
couples can only marry in their late 20s and need to get permission
from their employers to have a child.…read more
