Population and resource relationship
Optimum population
The ideal size for the wealth of a country and quality of life for its inhabitants.
Hard to establish as it changes overtime and in reality countries trade resources
so aren't self reliant.
Under population
A country has fewer resources to support its population. Due to uneven spatial
distribution of world's population. Some countries were only recently settled so
haven't had time to grow. Australia until recently was populated by small
indigenous populations at low levels of technological capabilities, who didn't need
to occupy all its territory so more resources need to occupy all its territory so
more resources are available to the population than it needs.
Over population
When a country's population exceeds optimum level of resources. Consequences
include social and economic issues (malnutrition, famine, unemployment,
overcrowding, poverty and war), environmental issues (land degradation, soil
erosion and desertification). However these may not be due to over population but
rather due to uneven distribution of available resources amongst the population.
Malthusian beliefs
World's population growth will outstrip resources leading to consequences such as
war, famine and disease. A increase in population lead to increase in demand for
food leading to less food per head resulting in increased mortality and decreased
fertility rates. However, Malthus was influenced by events before the 18th
century and wouldn't have foreseen technological advancements in agriculture that
allows resources to be produced well above mathematical predictions.
Evidence for Malthusian views
Famine: large famines in sub Saharan Africa in 1980's
Environmental issues: increased pollution, climate change, loss of
biodiversity, deforestation and desertification caused by increased
population as population puts pressure on natural resources leading to their
exploitation. Desertification: population growth led to increased demand
for meaning more land is cultivated and more cattle are grazed on the same
area of land and so land can't recover leading to desertification.
Health: death rates rise and life expectancy fall due to overpopulation and
not enough resources to sustain population

Resource optimist's beliefs
Either population growth will slow before limits of resources are reached or
humans will solve resource problems when they arise. Technological advancements
allow humans to cope with increasing population and that we can adapt to this. A
increase in population leads to increase in demand for food but technology will
lead to continuation of population growth as it will allow enough food for the
growing population.…read more

trade leading to exploitation of resources. However, it has shown that technology
and human adaptation has given a solution to overpopulation recently.

due to remote location. Increasing population- worries population growth
will outstrip food supply.…read more
