  • Food and environment: 
    • Environmental issues associated with food production:
      • Impact on climate change - from greenhouse gases produced by food production
      • Meat and dairy food production causes a lot of greenhouse gas production
      • Lots of energy from non-renewable fossil fuels used to produce food, especially meat and dairy foods - causes production of greenhouse gases
      • Greenhouse gases trap heat and warm the planet, which causes climate change
    • Climate change effects:
      • Drought (lack of water): crops fail, livestock die, soil blows away, forest fires damage farmland and kill livestock
      • Flooding: soil and soil nutrients washed away; land polluted by sewage, stones and rubbish; livestock drown; landslides damage farmland
      • Gales and hurricanes: damage to crops, farmland, buidlings, livestock killed
      • Higher or lower than normal temperatures: affects how crops grow; pollination of crops by insects affected; insects, moulds etc. will grow in large numbers; species of plants die out and get replaced by others; livestock may die
      • Extreme storms: crops damaged; livestock affected; water and soil polluted
  • Food packaging:
    • Why is it used and what are the effects it has on the environment:
      • Packaging protects food from microbe contamination
      • Packaging preserves food…
