Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. This means we need more food.

One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material (遺傳物質(zhì)). Foods from plants grown in this way are called genetically modified foods (轉(zhuǎn)基因食品), or GM foods.

By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared (準(zhǔn)備), for example, which stops people from becoming blind.

Rich countries produce GM food because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.

GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.

89．Why do some people not like GM foods ?　　　　　　　　　　　 　　　　　　　

　　　 A．They are not useful. B．They are not helpful.
