Water Pollution
Water
For good health it is good to use
In order to have good health, people must use clean and safe water. Safe drinking water is water which is free from all impurities that
cause pollution. Water pollution causes diseases such as typhoid, dysentery, cholera, diarrhoea and many others. It also kills fish and other
animals.
Clean / health
clean water. Water with impurities
Water pollution is mainly caused by people’s bad use of their water
resources. In some countries people throw human and industrial waste
into rivers and lakes. In others they throw chemicals and pesticides into
streams. Water which contains these substances is dangerous for all
people, animals and plants, because these substances are not natural.
1. Pollution by substances
Water can also get polluted from within the water supply system.
For example, all over the Sudan people keep their drinking water in a
water pot called “zeer”. It has been found that if the zeer is not cleaned
and covered, the water becomes polluted and causes diseases. Also, if
people use dirty containers to remove water from the zeer, the water
becomes equally polluted. Some people try to avoid this problem by
fixing little taps at the bottom of the zeer. In this way, the person can
get water from the zeer without putting his hand inside it, so the water
stays clean.
Impurities / Diseases to people and
animals
can cause a lot of diseases, both to
animals and to people.
Water is polluted when people throw
chemicals in it.
Also, water from a zeer can be
dangerous if the zeer is not covered
or if we don’t clean it well.
2. Pollution in the zeer
Cover the zeer
Clean the zeer

Once upon a time, a Tortoise lived in a pond with two Ducks, who were
her very good friends. She enjoyed the company of the Ducks, because she
could talk with them to her heart's content; the Tortoise liked to talk. She always had something to say, and she liked to hear herself say it.
After many years of this pleasant living, the pond became very low, in a
dry season; and finally it dried up. The two Ducks saw that they could no
longer live there, so they decided to fly to another region, where there was
more water. They went to the Tortoise to bid her good-bye.
"Oh, don't leave me behind!" begged the Tortoise. "Take me with you; I
must die if I am left here.""But you cannot fly!" said the Ducks. "How can we
take you with us?". "Take me with you! take me with you!" said the Tortoise.
The Ducks felt so sorry for her that at last they thought of a way to take
her. "We have thought of a way which will be possible," they said, "if only you
can manage to keep still long enough. We will each take hold of one end of a
stout stick, and do you take the middle in your mouth; then we will fly up in
the air with you and carry you with us. But remember not to talk! If you open
your mouth, you are lost."
The Tortoise said she would not say a word; she would not so
much as move her mouth; and she was very grateful. So the
Ducks brought a strong little stick and took hold of the ends,
while the Tortoise bit firmly on the middle. Then the two Ducks
rose slowly in the air and flew away with their burden.
When they were above the treetops, the Tortoise wanted to say, "How
high we are!" But she remembered, and kept still. When they passed the
church roof she wanted to say, "What is that tall building?" But she remembered, and held her peace. Then they came over the village square, and the
people looked up and saw them. "Look at the Ducks carrying a Tortoise!"
they shouted; and every one ran to look. The Tortoise wanted to say, "What
business is it of yours?" But she didn't. Then she heard the people shout,
"Isn't it strange! Look at it! Look!"
The Tortoise forgot everything except that she wanted to say, "Hush, you
foolish people!" She opened her mouth,—and fell to the ground. And that was
the end of the Tortoise.
It is a very good thing to be able to hold one's tongue!
