示范答案：
Already there is a vast array of foods available in supermarkets, imported at great transport costs from all over the world. In theory, the choice ought to expand even further, but increasing transport costs and the effect of producing food for rich countries by poor countries scarcely be able to feed their own populations may cause the choice to be less in the future.
