预测主题之三：食品安全

　　Food Safety

　　Currently, many problems concerning the safety of food have popped up. As for me, I believe at least three factors account for this issue.

　　First, I observe that profits drive many food producers to commit illegal things. They aim to gain more money at the expense of consumers health. Second, the overuse of agricultural pesticide has resulted in the degradation of food quality. The excessive pesticide bears enormous health hazard for people. Furthermore, some food producers inject hormones into domestic animals so as to make them grow more quickly and thus they can turn in more profit. As a result, peoples health has been seriously disturbed.

　　All in all, food safety is such a great concern, and we all should do establish laws and implement them effectively to avoid producing toxic foods.
