Consuming resources

• anything that can be used to meet a human need
• divided into two types: human and natural
• BIOLOGICAL RESOURCE: anything living
• ENERGY RESOURCES: fossil fuels and renewable energy sources
• MINERAL RESOURCES: mineral ores and building stones
• PHYSICAL RESOURCES: features or processes in the landscape that humans can utilise such as land, water, geothermal heat and sunlight

• the availability of a resource depends on the place becuase resources are not evenly distributed, it costs too much or many places are protected
• the richest 20% of the worlds people consume 82% of the worlds resources

OBTAINING OIL:

• Russia and Ukraine hit a dispute over oil in January 2006
• Russia has a vast supply of oil and gas
• impacted on the UKs prices
• political tension in the Middle East

CONSUMING OIL:

• not everyone can afford it
• very dependant on oil for everyday life
• hot water and electricity
• used in farming

TARSANDS:

• use chemicals to separate oil and sand
• toxic slides
• 1.34 million cars = the same emmisons that are produced there
• 60km of toxic ponds
• Athabaska river is getting toxic sludges around it

• an energy source that never runs out
• resources are running out (peak oil)
• coal produces CO2 which traps heat and can create climate change
• overeliance on finite resources which increases prices
• costs of importing

HYDROELECTRIC POWER:

• operating costs are low
• creates a constant energy
• no pollution and acts as a tourist attraction
• hard to find suitable sites
• lots of people have to be relocated

• Total population: 7.2 billion
• fast growth of population: exponential growth

  MALTHUS:

• believed that population grew exponentially but food production grew arithmetically
• population would eventually outstrip food supply
• population would decrease due to starvation (example of a natural check)
• he believed that population would decrease but then increase again to the next natural check

BOSERUP:

• she argued that food production does not limit or control population growth
• she believed that people would try not to give in to disease or famine, instead they would invent solutions to the problems
• used the term 'agricultural intensification' to explain how farmers can grow more food from the same piece of land
• fish farming and draining marshlands

• FOOD SECURITY: the ability to obtain sufficient food on a day to day basis. People are considered to be this when they do not live in fear of hunger
• RESOURCE: a natural occurring substance eg. Water
• FODD INSECURITY: this is when it is difficult to obtain sufficient food. This can range from hunger to full scale famine

FORD EDGE:

• hydrogen powered
• only emitts water vapour
• zero emissions vehicle

TATO NANO:

• cheaper car
• target audience is India
• more people will buy it which means emissions with increase

HYDROGEN:

• no harmfull emissions
• best usea are for heating and transport
• safe and already used in the chemical and other industries
• only product is water
• refuelling is quick

• SUSTAINABLE DEVELOPMENT: development that meets the needs of the present without compromising the ability of future generations to meet their own needs
• agenda 21 is a UN sustainable development programme agreed a various earth summits
• the EU target rate for recycling is 50% by 2020
• Brighton and Crawley have one of the lowest rates in the UK at just 25.6% and 26.1%

EDUCATION:

• Ealing in London offers: 240 litre wheelie bins for paper recycling which are emptied for free
• advise on reusing materials and bins for cans and compost bins

CONSERVATION:

• reducing domestic energy consumption and improving insulation in houses

RECYCLING:

• average person in England disposes of 263kg of waste every year
• UK produced 7 million tonnes of food waste in 2007
