Air transport is increasingly used to export types of fruits and vegetables to countries where they I think the fruits transport from other countries to the places which is lack of is reasonable. The following is my explanation. In the first place, the fruits and vegetables planted in other countries have a guaranteed quality. Compared to the local plants, the procedure of investigation is stricter. When the merchant transport them across the border, the customs would keep an eye on them, and examine the quality of them. As a consequence of the goods have to cross two boarders, their producing countries and the exporting countries, the examination has to be executed twice which guarantees the quality of the vegetations. Moreover, for those people who want to eat the non-seasonal vegetables, the cross-boundary food can be a good choice. At least, for the country where they are grown, these foods are seasonable and healthy. However, the vegetable and fruit market is filled with green-house foods which are ripened by hormone and pesticide. Compared to those foods, the foreign seasonal foods is definitely much healthier. As for the opponent who recognized the transportation foods as something justifiable, I think communications should be undergone between the voters and the opponents. For example, the opponents inquire that the variety of the biologist can be affected. Then the specialists should stand out and told them the rates of the biology invasion and give their proofs. In my opinion, we should support the policy that transport of the increasingly use of export types of fruits and vegetables to different countries to meet the fundamental meets of people. And something should be done to guarantee this policy where the opposing voices should be heard.
