　　参考范文

　　The advanced transportation and more diverse food preference render it possible and necessary that people can choose food which is not cultivated locally. As popular to some extent it might be, I do not suppose that it is a wise choice to follow this trend without second thought.

　　The food, cultivated and sent from other places, can offer more choices for the ordinary customers indeed. This is because their options for food are not only confined to their home-produced vegetables, fruits and meat, and they are likely to be bombarded with a wider range of food. This can subsequently intensify the competition between the food suppliers, and the customers can enjoy a relatively lower price.

　　However,compared with the benefits this practice can provide, leading a life that depends on food from other areas cannot be sustainable and turning to local food is thus environment-friendly. The local food means that the distance from farm to table is shorter and renders the transportation convenient. Without long distance transportation of food, the emission of exhaust will be cut down and less greenhouse gases will be discharged into the environment. In the meantime,delivering food from one place to another will consume a host of fuels because lorries or vans are driven by energies, it is really not so insightful to put such a heavy burden on the transportation only for the enjoyment of more food.

　　In conclusion, the local food is sufficient to sustain the locals to have a balanced diet and healthy life, more transported food can do little else and even bring about some environmental problems.
