The fast development of farming technologies and transportation systems gives people a choice between locally grown foods and imported (进口的) foods that are out of season in certain areas. When schools are faced with such a choice,more and more school dining halls are choosing the latter. The vegetables,fish and meat from farther places are much easier to prepare,because they have been washed and processed （加工) -They are sometimes cheaper than foods provided by local farmers. However,if we weigh the advantages and disadvantages,we will find that there are more benefits to using locally grown foods.
Generally,local foods can be said to be healthier than those that are transported from farther places. Foods from distant areas are usually processed or frozen,high in fat and preservatives(防腐剂). No doubt this will have a bad effect on teens health. The problem can be avoided if students are provided with local foods,which are always in season. Every day,local farmers are able to bring their vegetables to schools in several hours.
Locally grown foods represent a way for students to connect to their community(社区).It's a good chance for students to learn about what foods grow naturally in their area. Students nowadays know little about food production because they have no chance to learn about it. By knowing that the vegetables they are eating are fresh and were grown right down the road,they stay closer to local farms as well as the neighborhood.
Some people are worrying that using locally grown foods is not likely to work for schools in large cities. However,this is not a problem any more. In recent years,urban gardens have appeared in almost every major urban center. They provide many merits for comnumities. Food grown at home and by the people is nearly free. The only cost of it is buying the seeds and water used on the garden. More important is that these gardens provide a chance for people to meet and get to know each other.
Because of these reasons,schools should consider using local foods rather than those that are imoorted.
