Four Types of Resources

PHYSICAL: Natural material found below the Earth’s surface, such as soil and rock. Many rocks are used as energy sources or contain minerals and can become essential for human activity and making products

ENERGY: Resources used specially for heat. Fossil fuels can be burned, either for heat or to create steam to drive generators to produce electricity

MINERAL: Material normally quarries or mined from the ground in raw form and then heated and purified to become materials that are used (e.g. Steel is manufactured in to making cars.)

BIOLIGICAL: Resources with a biological origin that have developed through growth and development 

1 of 9

Global Resources - Non Renewable

E.g. Tar Sand, Oil in Canada


  • Extraction would bring further money to oil companies and countries which export the oil
  • Oil supply is important to developed economies


  • Extractions uses huge amounts of water and is very expensive
  • Mining creates visual pollution

Global Resources - Sustainables

E.g. Biofuels


  • Reduce dependence on fossil fuels
  • Co2 is absorbed when they are grown
  •  Petrol engines need little modification to cope with bio fuel instead of petrol


  •  Huge area of land required to grow the crops
  •  Reduced natural habitat variety due to manufacture
  • Deforestation of tropical rainforest

Global Resources - Renewable

E.g. Solar


  •      Almost unlimited
  •      Environmentally friendly
  •      Limited carbon emission


  •   Very expensive to set up
  •  Small scale so far so not possible to power the whole city with renewable energy
4 of 9


Renewable - Resources that can renew themselves without any human management (e.g. wind, sunlight)

Non-renewable - Resources that can't be remade/renewed, there is only a fixed amount available (e.g. coal)

Sustainable - Resources that can be managed so they renew themselves (e.g. wood)

Food Security - Ability to obtain sufficient food on a day-to-day basis. (They do not live in hunger)

Food Insecurity - Difficult to obatain suffiecient food. (lead to hunger and famine)

Oil Consumption Vs Solar Energy Consumption

Oil Consumption

  •  Oil is used in great ways in modern society: it fuels cars , hears buildings and provides electricity
  •  Oil is a finite resource oil consumption rose from ales than a million barrels a day in 1900 to 87 million a day by 2011
  •  Countries that are HICs use oil more

Solar Energy Consumption

  • Fossil fuels still generate 85% of global energy supplies, however as demand for energy grows and ‘peak oil’ is reached renewable resources could help fill the potential energy gap
  • Only some use it depending n where they live on the equator
  • Some countries may be too poor to develop technology for solar panels

Consumption theories

There are two different theories you need to know about how well the world can cope with current resource consumption. These are:

Malthusian Theory - Thomas Malthus

He believed that

  • Population growth went up geometrically: 2, 4, 8, 16 etc. (2 people have 4 children, those 4 children have 8 children between them.
  • Food production went up arithmetically: 1, 2, 3, 4 etc. - because improvements happen slowly
  • This meant famines would occur to limit population size naturally.
  • The poor should realise that having lots of children was only making them poorer

Reducing Carbon Footprints

Reducing Carbon Footprint

  •    Buy more seasonal food
  •    Switch light off when not in use
  •   Turn tap off when not in use

 Government Reducing Carbon Footprint

  •  Provide recycling bins
  •  Low emission zones
  •  Congestion charges

Businesses Reducing Carbon Footprint

  •   Using recycled product
  •   Eco friendly cars
8 of 9

Consumption theories

Boserupian theory - Ester Boserup

She believed:

  • Population growth would force people to be inventive to overcome the problems of food shortages and they would find ways to increase food production
  • Population growth is a good thing and that it is essential to human progress
