From field to basket

The food you choose has travelled a path before it reaches you, and that path changes the environment. Local, in-season food usually travels less and needs less energy to grow and store.

In the picture

  1. Seasonal fruit and vegetables: food that grows naturally at this time of year
  2. Tractor on a nearby field: a short trip that uses little fuel
  3. Cargo ship on a long route: far-travelled food uses more transport energy
  4. Basket: the same food, but with a different environmental cost depending on its journey

Examples

  • Buying apples from a farm near you in autumn instead of apples flown in from another continent
  • Choosing leeks and pumpkins in winter instead of out-of-season tomatoes grown in heated greenhouses

Quiz: From field to basket (Age 13)

  1. Why is food that is in season and grown nearby often better for the environment?

    • It usually travels a shorter distance and needs less energy to grow and store
    • It is picked earlier so it contains fewer nutrients
    • It is always packaged in less plastic
  2. A tomato is grown nearby but in a heated greenhouse out of season. What can we say about its environmental cost?

    • It can be as high as food that travelled far, because the way it was produced matters too
    • It is zero, because greenhouses protect plants
    • It is always low, because it did not travel far
  3. What is the main reason food carried on a long route, like by cargo ship, has a bigger impact?

    • Ships are only used for food that is not in season
    • Far-travelled food uses more transport energy
    • Food gets bigger when it travels
