One of the most important issues that many people in society concerned about nowadays is whether or not supermarket should only sell domestic food.

To begin with, it is true that the quantity of products which are produced within country is not adequate to the consumers ‘demands. The increase of resident land for buildings and apartments which are caused by the overburden population contributes to the decline of farm lands for agriculture.
