the population and resource relationship
optimum population
the ideal population size for the wealth of a country and the quality of life for its
if it is achieved then income per head and quality of life at at maximum levels for
that countries resources.
it is hard to establish a country's optimum population as it changes overtime and in
reality countries trade resources so as single country is not self dependent as it can
get resources through trade from other nations.
under population
when a country has fewer people than could be supported by its resources. this is due
to the uneven spatial distribution of the worlds population. some countries have only
recently been settled so the population has not had time to grow. canada and australia
until recently, only had small indigenous populations at low levels of technical
capability and didn't have the pressure to occupy all its territory, so they had more
natural resources than its population needs.
over population
when a country's population exceeds the optimum level for its resources. human
consequences include social and economic consequences such as malnutrition,
starvation, unemployment, overcrowding, poverty and war. environmental
consequences include land degradation, soil erosion and desertification. however these
consequences may not be due to overpopulation as a country may have enough
resources for its population but its resources may be unevenly distributed amongst
its population.
the North-East region of Brazil is an example of overpopulation as the population has
grown so much that peasant farmers cannot accumulate surpluses in wet years to
allow them to survive the periodic dry years due to their low levels of technology and
uneven distribution of land.
beliefs of malthusians
these are the pessimistic lobby who believe that the worlds population growth will
outstrip resources leading to the consequences predicted by Thomas Malthus, which
were catastrophes such as war, famine and disease. war would occur as humans would
begin to fight over food supplies and resources. these will in the long term, maintain a
balance between population growth and resources available. in summary, they believe
that an increase in population will lead to an increase in the demand for food which
will lead to less food per person resulting in increased mortality and decreased
fertility rates leading to an eventual decrease in population growth.
However, Malthus was clearly influenced by events that had occurred in or before
the 18th century and therefore he couldn't have foreseen some technological

In summary they believe that an increase in population will lead to an increase in the
demand for food, like malthusians however improvements in technology will lead to a
continuation of population growth as humans can provide enough food for the growing
population due to technology.
evidence for resource optimists views
famine: causes of famine have been political: they were nothing to do with
overpopulation.…read more

Easter island is the world's most isolated inhabited piece of land and was settled in
400 AD. there were large amounts of natural resources available such as fertile
volcanic soils, wood from sub-tropical forests, fresh water and volcanic rock for
making tools. at its peak, Easter island's population was between 7,000 and 20,000 in
the years 1400 to 1500 AD.…read more
