Sustainable food vocabulary

Here is a list of key words about sustainable food and food miles:

  • sustainable - if a food source is sustainable it means it can continue to be used without running out. For example, if we always fish in the same part of the sea and never allow the fish population to breed and grow again the fish supply in that area will eventually run out.
  • local - a place close by, somewhere near to where you live. A shop in your town would be your local shop as opposed to a shop you had to travel to.
  • imported foods - foods that have been brought into a country from another country to be sold.
