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. |
