As is symbolically portrayed in the pictures， with the speedy social and economic development， the number of fishes has sharply decreased. In one picture， there were various kinds of fish and only one fishing-boat in 1900. On the contrary， in 1995 there was only one fish， but many fishing-boats. The purpose of the pictures is to show us that due attention has to be paid to the decline of ocean resources. Owing to over-fishing， the number of fishes has obviously shrunk. If we let this situation go as it is， we do not know where fish will be in the forthcoming future. By that time， our environment will suffer a great destruction. Hence， it is imperative for us to take drastic measures. For one thing， we should appeal to our authorities to make strict laws and regulations to control commercial fishing. For another， we should enhance the awareness of people that the ocean resources are vital to us. Only in this way can we protect our ocean resources. Also I reckon that we humans can overcome this difficulty， and we will have a brighter future.
