the effcts on buying foods With the development of global economy, it is true that people can purchase numerous kinds of food both from home and abroad (国内外)in recent years. In my opinion, the positive effects of this trend outweigh the negative effects. （In recent years, it has become far more normal for people to purchase foods from abroad.） On the one hand, this practice might bring air pollution and a waste of energy, which will pose a threat to our environment. As we all know, foreign foods are mostly transported by ships and planes, which need to consume a lot of fossil fuels. As a kind of non-renewable sources, the more exotic foods people consume, the less energy there will be. Besides, during the process of transportation, the gas emissions from ships and exhaust fumes from planes will lead to global warming, which may have a devastating effect on our planet in the future. However, I would argue that these drawbacks are outweighed by the benefits. Firstly, if residents have easy access to more kinds of foods form other countries, it will decrease individuals' costs of living. This means that with the increasing number of exotic foods, local foods might face a fierce competition. Therefore, to compete with them, most food retailers will decline the prices of foods. Consequently, inhabitants can spend less money on foods, and they can use this money in other aspects, which can help them improve the quality of life. Secondly, this practice can also boost the economy of other countries and provide more job opportunities in food industry, since the increase of the sales volume of foods. In conclusion, while there are some detrimental effects if people buy food from overseas, I would argue that this trend brings more benefits than drawbacks.
