Passage1
As is en from the two graphs, it is clear that with the rapid growth of U.S. population from 1800 to 1900, the number of wildlife species on the verge of extinction is experiencing a similar trend. We can easily draw a conclusion that the sharp decline of wildlife species resulted from the population growth. As human population increas, the species of wildlife decline, and some are
even on the brink of extinction.
We may cite a variety of reasons for this situation. But the most contributing one is human being’s weak n of wildlife protection which leads to the decrea of wildlife as a result of cas of illegal hunting and killing of wildlife for profits. Besides, the destruction of ecological environment also plays a pushing role. Less and less forest and pasture coverage with more and more soil erosion due to population problem make it even more difficult for the wildlife to survive. Hence, unfortunately but naturally a soaring number of human population comes in tandem with a descending variety of wildlife.
Ecological environment construction and protection is a pressing and long-term task. To tackle the problem calls for, above all, the government’s efforts to control population growth and to enhance the laws to forbid wildlife hunting. Moreover, common citizens should take practical actions to protect wild animals as well as our living environment.

Passage 2
As we can e from the two pictures, great changes have taken place in the world commercial fishing. In 1990 there was only one ship in the a rich in fish, while in 1995, with the increasing number of fishing ships, only one fish could be found in the ocean crowded with ships. Obviously, the ever-deveolping fishing industry had a devastating effect on the fishing resource.
The purpo of the drawer is to warn people that we should spare no efforts in protecting the resources in the a by well managing the development of the fishing industry. This kind of profit-oriented fishing can only bring about the ecological unbalance. In addition, profit-pursuing makes people exploit other kinds of natural resources unlimitedly and blin
dly without considering the potential damage that can be done to nature, and more important, to human beings.
It is known to all that effective measures should be taken to deal with the problems of over exploitation of our natural resources. For one thing, laws should be enforced and obrved to keep the balance of nature by controlling commercial fishing. For another, people should be educated to realize the value of the resources. Only in this way, can this problem be properly solved.
Passage 3
无偿献血新闻稿As is shown in the pictures, with the rampancy of commercial fishing, the number of fish dramatically (sharply) decread. From the pictures we can e that there were various kinds of fish and only one fishing-boat in 1900. On the contrary, in 1995 there was only one fish, with many fishing-boats.

The purpo of this picture is to show us that due (great/ enough) attention has to be pai
d to the decline of ocean resources. Owing to over-fishing the number of fish has obviously dropped. If we let this situation continue as it is, we do not know where fish will be in the future. By that time, our environment will suffer a great destruction. google中国
Therefore, it is imperative for us to take drastic measures. For one thing, we should appeal to our authorities to make strict laws to control commercial fishing. For another, we should enhance 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.
Passage 4
A Brief History of World Commercial Fishing
This picture shows a drastic change in the world’s commercial fishing. The two parts display totally different scenes in 1900 and 1995. In 1900, there were a large number of fish while only one boat was fishing on the ocean. But in 1995 fishing boats incread sh

Judging from the picture, we can e that within about 100 years, humans have stripped the a of her generous offerings. If we don’t put an end to the trend, then the fish in the ocean could become extinct species in the foreeable future.
Therefore, it is high time we took effective measures to solve this problem. First, we must bring world population under a reasonable control, as over fishing is largely due to the need to fill the additional mouths. Second, every year in the fish’s mating ason, a "grace period" should be enforced during which the fish are allowed to reproduce themlves. Third, strict laws should be implemented. Last but not least, we should enhance the awareness of the public that the ocean resources are very vital to us. Only when the above mentioned measures are put into practice can we save the fish from disappearing completely.
