问题     Food can be produced more cheaply nowadays with improved fertilisers and better machinery. However, some methods may be dangerous to human health, and have negative effects on local communities. What is your opinion on the issue?

答案 Today, advanced technology is increasingly applied to food production so we can produce food more cheaply in larger quantities and wider ranges than ever before. The number of starving people in the world has been dramatically reduced over recent decades, and a wider variety of food can reach the common household. These obvious benefits cannot be denied. Despite all these merits, it is believed that some of the methods used in food production are dangerous for consumers’ health. For instance, the wide use of some chemical fertilisers and pesticides, though increasing productivity, also threatens people’s health because some chemicals will remain in the food and be detrimental to one’s fitness. Another disadvantage is the potential impact on local communities. For example, as a result of the wide use of modern machinery and advanced farming techniques requiring less manpower, many people have moved from rural communities to urban areas to find work, destroying rural communities that have existed for generations. Also, people are worried about the genetically modified foods that are becoming available. Although most scientists agree that they are safe to be part of our diet, the fact is that there might be unknown long term effects of consuming them. To conclude, I think that some methods involving modern technologies are indeed harmful to both human health and local communities. But that is not to say that we should return to a barbarian lifestyle. Rather, practical solutions should be worked out to maximise the benefits of farming technology and to minimise its side effects.
