答案     With the rapid development of science, many modern agricultural technologies, such as fertilizer and modern machinery, have been applied with the view to enhance the output of produces. Undoubtedly, this increases the volume of crops. But in the meanwhile, some people show their great concerns about the negative effects aroused by modern agriculture.
    Firstly, the utilization of fertilizer causes great changes of the structure of soil. In the long run, this will make the soil infertile, which means that we can only have a good harvest with the help of fertilizer. Furthermore, the change of the structure of soil can cause serious environment problem.
    Secondly, pesticide can kill most of the insects harmful to crops. But at the same time, it also kills many insects, which are friendly to the crops and human beings. The abuse of pesticide also seriously threatens the health of human beings. When people eat the vegetable and crops with pesticide sediment, their health will be in danger and their digest system and neural system will be damaged.
    Finally, the use of modern machinery saves people a lot of time and energy. But this will cause serious environmental problems. In the ancient times, most of the field labour is undertaken manually or with the help of some tamed animals, such as cattle and horses. But now, modern machinery takes the place of human beings and animals and plays a major role in modern agriculture, which will cause serious environment pollution and the scarcity of natural resources.
    To sum up, the employment of modern technology helps to improve people’s living, but meanwhile, we should raise the awareness of protecting our environment and us and takes some measures to ensure people’s health.
