- 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
- Overfishing
- Reducing the number of stages in the Food Chain
- Biofuels
- Made by Fermentation
- Ethanol is made by Anaerobic Fermentation of sugar
- Glucose > Ethanol + Carbon Dioxide + Energy
- Ethanol is made by Anaerobic Fermentation of sugar
- Biogas
- Made by Anaerobic Fermentation of Waste Material
- Creates Fertiliser
- Made by Fermentation
- Managing Food Production
- Deforestation

- Managing Food Production
- Creates more Methane and Carbon Dioxide in the atmosphere
- Less Carbon Dioxide is taken in as a sink
- There is less Biodiversity
- B3 - Humans and the environment
- Creates more Methane and Carbon Dioxide in the atmosphere
