In the modern world, some things can be done by communication without ever leaving your house. For example, to read a book you can download it without the need to go to a bookstore and pick it up. Family members can communicate over the telephone without having to travel to physically meet up in the same location. However other things still require and always will require physical transport. A perfect example of this is food. To eat something, it has to be on your plate in front of you. The distance that a piece of food travels from farm to kitchen plate is known as its "food miles". The typical food has gone between 1,500 to 2,500 miles before you get to eat it.
