  • B3 - Humans and the environment
    • Managing Food Production
      • Reducing the number of stages in the Food Chain
        • Therefore more energy is transferred between trophic levels
      • Restricting the Energy lost by Farm Animals
      • Developing new food sources like Mycoprotein
      • Problems with Food Production
        • Overfishing
          • Controlled by Fish Quotas and Net Size
        • Food Miles
        • Crowded conditions on Factory Farms
          • Higher chance of spreading disease
          • Fossil Fuels are burnt to keep animals warm
    • Biofuels
      • Made by  Fermentation
        • Ethanol is made by Anaerobic Fermentation of sugar
          • Glucose > Ethanol + Carbon Dioxide + Energy
      • Biogas
        • Made by Anaerobic Fermentation of Waste Material
        • Creates Fertiliser
  • Deforestation

          • Made by Anaerobic Fermentation of Waste Material
          • Creates Fertiliser
    • Creates more Methane and Carbon Dioxide in the atmosphere
    • Less Carbon Dioxide is taken in as a sink
    • There is less Biodiversity
  • Creates more Methane and Carbon Dioxide in the atmosphere
