[精美语篇]
With the increase of commercial fishing, the number of fishes sharply decreased. Great attention has to be paid to the decrease of ocean resources. Owing to over­fishing the number of fishes has obviously dropped. If we let this situation go as it is, we do not know where fish will be in the future. By that time, our environment will suffer great destruction.
Therefore, it is imperative for us to take effective measures. For one thing, we should appeal to our authorities to make strict laws to control commercial fishing. For another, we should arouse the awareness of people that the ocean resources are very vital to us. Only in this way can we protect our ocean resources. Also I believe that we humans can overcome this difficulty, and we will have a brighter future.
