Resource = Any aspect of the environment which can be used to meet human needs
Natural/Human:
Natural = naturally occuring substances which have value by humans, eg. oil, fish forests
Human = number of people and their skills and abilities
Renewables:
Non-Renewables: Take millions of years to form and therefore, within the Human timeframe, there is a finite amount available which can be over exploited
Renewables/Flow resources: Dont need regeneration and in constant supply - eg wind, solar, tidal energy. Due to technoglogy, such resources arnt used to their full potential but will inevitably be overcome due to the lack of finite resources left
Semi-Renewable: Resources which are considered renewable as they can regenerate in a human time frame - eg Forests. However, can be lost if over exploited. Another example is Fishing, whereby years ago they would have been considered renewable, but due to the threa of overfishing, have to be protected to avoid extinction.
