[00:01.19]As is shown in the pictures,
[00:03.74]with the rampancy of commercial fishing,
[00:06.26]the number of fish has dramatically shrunk.
[00:09.19]In the first picture,
[00:10.80]we learn that the year 1900 witnessed a quite encouraging scene of world fishing.
[00:17.13]There were various kinds of fish and only one fishing-boat.
[00:21.19]On the contrary, in the second picture,
[00:23.97]in 1995 there was only one fish swimming freely but many fishing-boats sailing in the sea.
[00:31.65]It is apparent that a disastrous change has occurred.
[00:35.56]The purpose of the pictures is to tell us
[00:38.57]that due attention has to be paid to the reduction of ocean resources.
[00:44.02]Owing to the over-exploitation of marine resources,
[00:48.01]the number of fish has declined at an accelerating rate.
[00:51.62]If we let this situation continue as it is,
[00:54.83]we do not know where the fish will be in the future.
[00:58.06]By that time, our environment will suffer a great destruction.
[01:01.96]Hence, it is imperative for us to take drastic measures to reverse this disturbing trend illustrated in the above pictures.
[01:10.84]For one thing, we should appeal to the authorities to make strict laws to control commercial fishing.
[01:18.06]For another, we should cultivate the awareness of people that ocean resources are of great significance to us.
[01:24.80]Only in this way can we protect our natural environment.
[01:29.07]I believe that we humans can surmount this difficulty and we will have a brilliant future.
