　　Task2：The range and quality of food that we can buy has changed because of technological and scientific advances. Some people regard this change as an improvement, while others believe that it is harmful. Discuss both views and give your opinion.

　　Advances in science and technology have led to significant changes in the range and quality of the foods that are available to consumers. Opinions are divided on whether this development is beneficial or detrimental.

　　On the one hand, there is a much greater variety of foods available now, thanks to improvements in refrigeration and transportation. In the past, because it was not possible to keep food for fresh for more than a few days, people could only consume products made locally, or within easy reach of their local area. In contrast, nowadays, it is possible to freeze produce such as meat and milk, or to keep fruit and vegetables fresh for several days by storing them at a low enough temperature. This, along with more efficient transport systems, enables the provision of fresh products to almost anywhere in the world, which means that people living in northern latitudes have access to tropical fruit all year round.

　　On the other hand, not all technological advances are beneficial, and there are dangers for consumers of genetically modified and of highly processed food. With regard to the former, this relatively new technology has never been proven safe in the long term studies. As a result of its introduction, there has been an increase in the number of people suffering from certain chronic diseases, and many doctors now recommend that their patients avoid food made from GM products altogether. As far as processed food is concerned, the industrial production of these products tends to destroy the vitamins and other nutrients, and at the same time, unhealthy ingredients are added, such as vegetable oil and MSG, which may be extremely detrimental to people’s health.

　　In my opinion, while it is true that there is a much larger selection of food available now, the quality is not necessarily higher because of the use of processed and GM products. Consumption of these new foods must be very careful to avoid undesirable results.
