- - - - Food Miles
        
        Transporting food is very expensive and has a large carbon footprint
        
        This comes from all stages of production and transportation
      - Kenya
    - - Organic Produce
        
        Organic produce is grown without use of chemicals, it is more expensive and relies on seasonal foods.
        
        Riverford Organic Farms, Devon
      - Agribusiness
        
        Intensive farming maximising production, relying on technology and chemicals.
        
        Lynford House Farm, East Anglia
      - There is a concern about the reliance on imports as this could lead to food insecurity
    - - The UK is no longer self sufficient
      - About 40% of UK food is now imported
        
        The demand for exotic foods is increasing
        
        Seasonal produce that can be grown all year abroad
        
        Imported is often cheaper
        
        Cost of production in the UK is higher
      - Demand is increasing as population increases.
  - - - In 1990 75% of UK energy came from Non renewable sources
      - Now renewable energy is much more important energy source
    - - Nuclear waste can contaminate land
      - Hot water from power stations can damage ecosystems
      - Use of fossil fuels increases green house effect and acid rain
      - Visual impact on the environment
      - Noise pollution from power station, eg wind turbines
      - Hydroelectric dams can flood some ecosystems and remove water from others.
    - - Increasing as population increases and increased reliance on technology
      - In recent years energy efficiency has increased saving much of the energy produced in the UK
    - - Energy industry provides jobs
      - Renewable energy farms can reduce energy bills
      - Power stations are expensive to build , maintain and decommission
      - Energy exploitation can reduce tourism
    - - Positives
        
        Cheap gas for energy production
        
        Help to meet the rising demand for gas
      - Negatives
        
        Potentially could cause earthquakes
        
        Possibly pollute water supplies
      - Fracking enables the extraction of gas from shale by cracking the rock using high pressure steam
  - - - The South and East has a water deficit
      - Water Stress
        
        Saving water can reduce water stress by using water meters, using recycled water and more efficient domestic appliances.
        
        Grey water, waste from domestic homes, can be used to water fields
        
        This is where demand is greater than supply
      - The North and West has a water surplus
    - - Bacteria killed using Chlorine
      - Restricting land use around reservoirs and recreational use of the reservoir
      - Filter the water to remove sediment
      - Imposing regulations on water usage
      - Monitor the quality in rivers and drink water reservoirs
      - Causes of Groundwater contamination
        
        Waste from Industrial sites
        
        Leaching from mines or quarries
        
        Water cooling from Power stations
        
        Runoff from chemical fertilizers from farmland
    - - Demand is increasing as population increases.
      - About 50% of UK supply is used domestically
      - 21% of supply is wasted through leakages
