Air transport is increasingly used to export types of fruits and vegetables to countries where they cannot be grown or are out of season. Some people say it is a good thing, but other people think it can’t be justified. Discuss both views and give your own opinion. The speed of this world is changing rapidly. In the past, people do not have capability to eat the exotic fruits and vegetables and greenhouse food. But now, the flights solve this problem. This phenomenon leads to some controversies between the supports and opponents. I will analysis both and give my arguments.Obviously, with the development of air transport, it helps people have more opportunities to taste a variety of fruits and vegetables from all parts of world. This action brings convenience which diversified people’s dinner tables. In addition, import and export can stimulate the local and foreigner commodities’ circulation and development, and bring some tax revenue to both countries. However, some people believe that this practice has some disadvantages. First of all, transport those food need the preservation technology which can keep the food fresh.But some preservatives contain some negative chemical stuff that have a detrimental influence upon humans’ physical health. Furthermore, some animals and plants are not harmful but when they penetrated in the export food and traveled by air transport, and then arrived their destinations, those creatures would invade new environments which do not have natural enemies to control their population. As a result, the domestic environments would be damaged. That is biological invasion. I personally think that exporting the exotic fruits or greenhouse vegetables to another countries is reasonable.But we need to consider another element, the domestic quarantine service should regulate all food bring from abroad(overseas) strictly, it is not only measuring the chemical preservatives in the food, but also eliminating the invade creatures to protect the local environments. In conclusion, I think we need to reinforce the regulate on the imported goods rather the reject them. In fact, that can benefit the people’s need and protect the environment and promote the circulation of commodities.
