　　现代化农业的利弊。

　　Modern technology such as chemical fertilisers and machinery, provide people with cheaper food, but it causes negative impacts on people’s health. Do you think the advantages of it overweight its disadvantages?

　　支持正方

　　Large scale production by machinery focuses on efficiency at the cost of quality -­‐ lose the taste of nature, e.g. home-­‐made produces are more popular and expensive worldwide.

　　Some technology is damaging to human health, e.g. pesticide. What is more, to prevent food from turning spoiled, many producers use chemical preservers, harming people’s health.

　　Bio-­‐technology, if not well handled with full responsibility, will threaten food security, e.g. some producers use growth hormone to feed poultry and livestock.

　　Certain irresponsible countries are exporting sizeable genetically modified food to other less developed countries, and even go so far as to monopolise food market at those countries. It is worth noticeing that the effect of genetically modified food, whether benign or malign, is not yet determined.

　　支持后者

　　Mass production made it possible for food producers to limit their cost, and sell food in much larger quantity and with much cheaper price than before.

　　It also means that more options are largely available to consumers, since the sizeable production and efficient transport eliminated the barrier of distance, e.g. Canadian people can enjoy pineapples in winter. 国家进口食物的利弊
