Resources and oil

A resource is defined as any aspect of the environment that can be used to meet human needs. Geographers classify reources as being either renewable or non-renewable.

Non-renewable resources - took millions of years to forms and the amount available is strictly limited. Once consumed, they cannot be directly replaced within a known human time-scale.
Renewable resources - naturally replenishable as they will always exist and occur independently of any human presence or use.

You need to know and understand:

• How resources can be classified
• The lifecycle of a resource.

Oil - a case study of a non-renewable resource
You need to know and understand:

• Details about the exploitation and management of oil;
• The environmental impact of resource exploitation.

Homework activity
Carry out some research into a recent (within the last 5 years) oil spill. Including:
~ Where it happened
~ The environmental impacts
~ Clean up
You could find this by simply typing 'oil spill' into BBC News search.
Due in: Mon 29 Sept (this should take you between 30 minutes and 1 hour)

Finish your mindmap from the lesson if necessary!!

Population pressure and resource management

Malthus said that bacuse population grows geometrically and the rate of food production can only increase arithmetically, at some point in time population size would be limited by the amount of food available.

The Club of Rome was also pessimistic about the abiliy of the human race to support itself in the future. They predicted that limited food supply, a lack of resources, industrial decline and pollution would limit population growth and seriously affect the quality of life.

However, writer such as Esther Boserup were more optimistic. She predicted that growth in population and the demand for more food would trigger technological innovation and increase agricultural production.
