Radiation pollution can cause the death of many
people. We can get information from paragraph ...
There many kinds of pollution. They can be grouped into several major classifications, of which we mention here; water pollution, air pollution, noise pollution and radiation pollution.
Air pollution is caused by car engines and by big factories with large chimneys through which dirty air escapes.
Land pollution can be caused by waste or rubbish such as paper, bottles, alumunium, scraps, junk, etc. Because of our carelessness and laziness, our surrounding are very dirty. They are filled with household as well factory waste. Some waste can be broken down by natural organisms such as bacteria. Rubbish like this is called organic waste. On the other hand, rubbish which cannot be broken down by natural organisms is called in organic waste. This is more difficult to dispose of and it makes the surroundings very unpleasant to look at.
Noise pollution can be caused by several thins; loud music through loudspeakers, the noise of motorized vehicles such as trucks, buses, motorcycles,
and also aircraft. Loud noise may caused deafness. It
can affect the heart and cause nervous strain.
Radiation pollution can kill many people in one moment. It is caused by uranium and other radioactive. The testing of atomic weapons is feared by people in
general because atomic weapon are radioactive. These
are a few example of the different kinds of pollution in our lives.

CASTOR FUEL AND LIGHT
The air we breathe contains the gases oxygen and nitrogen, and small quantities of other gases. Every gas consists of molecules of a particular substance, moving rafidly about. The molecules are comparatively far apart, but they fill evenly any vessel containing them. All gases can be changed to liquids, and some even to solids, if they are cooled down enough.
The oxygen used in factories for making a very hot flame to cut and weld steel is sometimes stored and carried about in the liquid state and solid carbon dioxide, usually called dry ice, is used for keeping ice- cream cold.
The kinds of gases used in cookers and gas fires come from three sources. The first kind is made3 of naptha, which is a light oil; the second is made from
coal; while the third, natural gas, is almost entirely
Geologists believe that natural gas was produced iron carboniferous, or coal-bearing rocks. The gas rose into the rock holes in the sandstone, and was prevented
from escaping upwards out of the sandstone by a "cap"
rock-usually a from of rock salt-which formed a dome over the natural reservoir of gas.
In Jakarta and other big cities in Indonesia it is common practice to use gas for cooking. Gas reaches the houses through large underground pipes called gas mains; and smaller pipes called service pipes lead to the gas meters in each hose or building. The meter records how much gas is used.
Natural and gas and gas from oil has no distinctive smell, so an artificial smell is produced by adding small quantities of concentrated a do rants, to enable people to detect any leak that may occur.
Pertamina sells bottled gas under the name of
The gas is put in steel drums or cylinders. Bottled gas is used by people who live places without a piped supply, by yachtsmen and campers. Indonesia's role in LNG production started in 1977 with the initiation of the LNG facility at Bontang. About a year later the plant at Arun also started production and exportation.

THE CENTURY'S GREATEST MAN OF SCIENCE
In 1894, when Albert Einstein was 15, his father lost money and could not support him any longer. Other boys would have left school and stopped studying. Not Albert. He left school for sometime, but he later managed to go to a better school, the Polytechnic in Zurich, Switzerland.
On leaving the Institute he discovered that no one would offer him the kind of job he wanted. At last he found a suitable one at the patent office in Berne.
Einstein's task at the paten office was to make an
investigation of the new products sent to his office. The job did not require much of Einstein's new products sent to his office. The job did not require much of Einstein's time, so he was able to write scientific articles. He published these in 1905. Scientists were surprised by what he had written. They were even more surprised when they knew that these articles, when could have been written by a university professor, were actually written by an official at a patent office.
Investigations were made and it was decided that the official should be taken from the patent office and given a more suitable job. A few years later, Einstein became a professor at the University of Zurich. In 1911 he taught in Prague, and later at the Polytechnic Institute in Switzerland, where he had been a student. Then he was requested to move to Berlin.
Einstein stayed in Berlin for 20 years, from 1913 to 1933. During that period he worked on his famous Theory of Relativity. He gave a simple example, in
simple language, to explain the idea of relativity. A
man riding on a train drops a stone out of the window. To the man on the train, it seems that the stone follows
a straight path as it drops. However, to a man outside the train, the part of the stone does not seem straight; it looks like a parabola. The theory; expands those of
Newton an Galileo, which are correct; only under
Einstein made very important contributions in the field; of physics. The Nobel Prize that he won in 1912 at the a of 42 was no surprise to the scientific world. No scientist beat him his field. What beat him was time. He died in: Princeton in the U.S.A in 1955. People believed that he was j the century's greatest man of science.
Why did Albert Einstein leave school? A. He found it difficult to find a job.
B. He went to a batter school in Zurich.
C. He was offered to work at a patent office.
D. Other boys left school and stopped studying. E. His parent could not finance his education.

A volcano is a mountain surrounding an opening in the earth's crust. Steam, gases, lava, ashes, and other material are forced out almost continuously from an active volcano. A dormant volcano, on the other hand, erupts at long intervals. In an extinct volcano, the crater has long been closed up with cold, solid lava.
Out earth was a sphere of gases which slowly cooled off from the outside, forming a thin crust of clod, solid materials, containing hot liquid, magma,
and gases. It was the very high pressure of the gases
forcing the magma through weak parts in the earth's crust that formed volcanoes.
Most of our volcanoes are in Java. The most active one is Mount Merapi at the north of Yogya. The northern I-part of the crater has a high wall, so in
eruptions the lava r flows in every direction. The hot
lava slowly cools off into what is called 'lahar'.
In the rainy season, when the cool "lahar" on Merapi's slopes is hit by rain it flows down the slopes with great force, destroying everything in its path. The flow of "lahar" mixed with rocks fills up the rivers, while sand covers the fields.
The eruptions of sea volcanoes cause high waves, flooding regions on the coasts. This happened when Krakatau erupted in 1833. The sound of the eruption was heard from places as far away as India and Australia, distance of 3,600 to 4,800 km from Krakatau. Around 18 cubic km of solid materials were thrown up. The skies above place as far away as the southern Pacific. Africa and South America were darkened. 30 meter high waves flooded the coast of Java and Lampung, sweeping away villages and 35,000 people.
However, volcanoes are also a great blessing. Volcanoes and mountains force the clouds to rise, and cool them off, causing them a drop the water they contain in the from of rain. The materials thrown up by volcanoes contain minerals needed by plants.
The higher regions, being cool, are good for coffee, tea and other plantations. The woods on the slopes protect the soil against erosion, while the soil
acts as a water reservoir giving water to the rivers.
Volcanoes are formed from ... A. moving lahar
B. solid materials
C. earth's crust

There is reason for the deepest concern about the plight of Wildlife in our country. Many rare species are threatened with extinction because of the greed of hunters game collections. Orangutan are rarely found in their natural habitat in the forest of Kalimantan and Sumatra, but one may find them in zoo and private menageries all over the world. Ruthless hunters kill innocent elephants for their valuable ivory tusks, or catch them alive to perform in circuses. Tiger's hides decorate walls and floors of rich people's home in distant countries.
If things are allowed to continue in this way, it is feared that very soon all wildlife will disappear from our forests. Fortunately, the government has now imposed strict law on hunting. Some areas are designated wildlife reserves where hunters cannot enter. These include Ujungkulon and Pangandaran in West Java, Merubetiri in East Java, and many more in the other islands.
Some time ago our newspapers contained reports of elephants which had run amok in the province of Lampung. They had emerged from their abode in the
forest and destroyed crops and houses belonging to the
villagers. The people could not understand why the beasts had suddenly gone wild. The strange thing was that the animals had not come for food, because having wrought destruction they returned to the forest. They seemed to have come only to vent their anger. As elephants are protected by law, the people could not kill any of them.
The explanation for the elephants strange behaviour is that they felt their quiet life had been disturbed by the timber-felling projects and saw-mills
set up deep in the forest.
The animals felt their domain was being narrowed by man, and so they got angry. Elephants need peace and quiet for their family life. They also need vast
areas of land in which to roam. They live in herds, and each herd likes to have its own territory.
Now the government has driven the elephants back into the forests, away from any village or lumber- mill. By shouting and shooting in the air the people
drove the great beasts to a new abode in the district of
Air Sugihan. It is hoped that they will feel at home there and can live in peace and quiet.
