Pollution and Super Pollution

-G. R. Taylor

Summary:

Simple kind of pollution is everywhere in this world. The Apollo 8 did survey of the polluted sites of the world and found that Osaka and Tokyo of Japan along with the Los Angeles of USA were equally polluted. Among them Los Angeles has got the highest or nastiest air pollution in the world. It has got 34 tons of dirt per square kilometer in comparison to the New York which has got 17 tons of dirt per square kilometer. The vehicles collide regularly or go out of road at day time due to invisibility. Traffic police have gone to take fresh air in every four hours. They regenerate fresh blood by taking oxygen from cylinders. The oxygen is put in cafes and shopping centers also and people can use it from coin-in-the-slot machines. Similarly, student should also wear mask in their classroom while taking lessons.

The pollution has been becoming a great or serious problem these days. We also discharge gases, acids, metals and poisons which harm our health. Pollution may be one of the parts of environmental problem; but we have done much harm to the earth. We increased heat and dust particles, cut forests and pave our fields. Similarly, we destroy one species and promote another. We also increase noise and pile the trash. There is limit of all the above activities.

If we pile less garbage into a stream, it can be purified by the river. If we dump much more, it will lose the purifying capacity and the water will be polluted. It will take another hundreds of years to be purified. To dump a small amount of garbage into the water was accepted in the past; now it happens too much. So it is called as super-pollution.

It is also same about the impact of man in the environment. We have been collapsing the natural processes by increasing heat and dust, cutting forests, paving land etc. It is known as ecological catastrophe which is difficult to recover in the future. It will be difficult to return back to the original condition; or it will take so long to come to normal condition. As a corollary there will be a permanent damage in the environment.

1.   Put the following four sentences in the right order, so that they read like a coherent paragraph.

a.       If sewage is dumped into a stream in small quantities, the stream dissolves it and purifies it.

b.      Ten miles further down, the water is pure again.

c.       But if the large quantities of sewage are dumped continuously, the purifying bacteria are killed and the stream loses its power to purify.

d.      This overwhelming kind of pollution is called super-pollution.

2.   Drawing your information from the passage given above, answer the following questions in complete sentences. Your answer to every question should not exceed 25 words.

a.       Where do most serious smog and polluted air exist?

Answer: It is in Los Angeles, Tokyo and Osaka.

b.      Describe two effects of this pollution.

Answer: They are: increasing heat and water pollution.

c.       How do we alter the environment? Name three ways that the author has mentioned.

Answer: We can alter it by decreasing heat and dust, afforesting and not paving the soil.

d.      Name two factors, that the author mentions, which can lead to an ecological catastrophe.

Answer: They are: destroying forest and increasing heat in the earth.

3.   Read paragraphs 16 and 17:

a.       Point out the topic sentence of each paragraph.

Answer: The topic sentence of 16 is “pollution is only a part of the story”; and in paragraph 17 the topic sentence is “I call it super-pollution”.
