Food

All food comes from a country. Each country needs to bring it to another country .It carries the food by planes, ships and trucks. All those vehicles create pollution and that's called food miles.

The idea behind the whole food miles thing is a very simple one – and the clue is, obviously, in the name; it is a way of expressing just how far the food we eat travels from the farm where it is first produced, before it ends up on our tables. In practice, however, it is not necessarily a straightforward thing to work out, since the journey from field to plate is not always a direct one. As a result, this distance may also include any number of other trips along the way, from farm to processor, from one processor to another, from processors to distribution centres, from there to the retailer and then finally to our homes. Worst of all, some of the journeys are very long indeed; in the fishing industry, for instance, there are tales of some of the fish caught in the North Sea travelling as far as China for processing, before making its way back to European tables.
