1.GLOBAL WARMING
Global
warming is a serious
threat to Earth, causing
many harmful
effect
on the environment and the ozone layer (which protect Earth from harmful sun ray's).
The first reason
for global warming is deforestation. Many trees get cut. They clean the air
This leads to
global warming.
To reduce
the effect of global warming people that cut trees should replant new
trees instead
to maintain
balance.
The second reason
for global warming is garbages. Too much packages around things we buy and
too many plastic
bags cause
global warming. We
must reduce the things we buys, recycle the garbage we make and not use so much
things. The
last reason for global warming is fossil fuels.
Fossil fuels
are burned
for energies.
If we did
not burn the
fossil fuels
we will not have the global warming. Smoke from factories, industries
and mainly nuclear
plants cause
global warming is not from one country but countries all over the
world.
Smoke needs to
stop and that means no more fossil fuels. We need to make more fuel-efficient
vehicles
and find
other
ways to make power. If we use everything the proper way, we can reduce global warming and
the Earth will be saved.
2. A Visit to
Zoo
Last Sunday, I went along with my
friends to a zoo. It is located near Purana Quila in Delhi. It is one of the
biggest in India. There were many beautiful birds, monkeys, lions, tigers,
cheetahs and snakes in the zoo. Apart from big animals, there were different
types of colourful birds in the zoo. The wild and dangerous animals like lions,
tigers and cheetahs were kept in different cages. We even saw a white tiger and
a gorilla in the zoo. Some of the animals were relaxing while some of them were
eating their food. We enjoyed seeing the acrobatics of the monkeys. I gave some
peanuts and bananas to them. Then, we went for an elephant ride. We enjoyed the
ride a lot. It was fun.
3.Mobile Phones- a blessing
in disguise
Think of those days when
telephone didn’t exist at all! People all over the world were confined to their
own small circle with no immediate knowledge of happenings in the outside
world. Then came in the big revolutionary discovery of the telegraph which was
our earliest mode of communication. But telegrams also took a long time to
reach the person to whom it was sent.
The marvelous invention of telephone by
Alexander Graham Bell helped in the transmission of voice and therefore made
connectivity more interesting and faster. It was followed by the modernized
version of bell’s machine, the mobile phones. But the general rule of science
is that every new discovery has its positive aspect and some negative effects.
There are some positive effects of this
new apparatus which would include faster connectivity which enables people to
keep in touch with their near and dear ones very easily. It helps us to track
people with the latest technologies that are provided in the mobile phones.
People on road would be able to contact others in case of problems for which in
the past times they had to run around to find a public telephone booth. Mobile
phones have made long distance or international calls faster and easier. With
the coming in of the more upgraded technologies and facilities provided in a
mobile phone, a phone is no longer just a phone. It has now become a computer
in a miniature form which can be carried around anywhere and everywhere. For
the gadget freaks, a mobile phone has become a play thing. Another way of
looking at the mobile phones is from the point of view of the teenagers for
whom it is the best way to keep in touch with friends.
But when we consider the question that
is this invention really a blessing, we can actually see that the very presence
of a mobile phone in the market has done more disasters than blessings.
Terrorists who misuse it have taken all the opportunities available through a
mobile phone to spread terror and devastation. The innocent youngsters have
started chatting with people they do not even know and just perhaps because
their voice sounds nice. Various kinds of immoral messages are delivered
through the phone to vitiate the young minds. Using mobile phones while driving
or crossing the road have caused a lot of accidents in recent years. And last
but not the least it has been proven that talking on mobile phones for long
hours have caused biological damage to the ears.
Mobile phones are
thus a double-edged sword that can be used to enhance the quality of our life,
but at the same time may also be abused by mischief makers. Again, it is up to
us as to how we take advantage of this great invention and use it to our
advantage.
4.Wonders of Science
In the past, there were only eight wonders in
the world. But today there are hundreds of wonders. Every invention of science
has changed this world into a land of wonders. These wonders are not only
beautiful but also useful.How wonderful our aeroplane is! We were not
born with wings. But we always wished to fly like birds. Science has given us
what God has not. Today we can fly to any corner of the world. Rivers and
mountains cannot stand in the way. How cheap and how easy it is to travel now!
Today we can travel even to the moon. Our jets and rockets will carry us there.
What a change from bullock cart to aeroplane!Our radio is even more wonderful.
What a useful servant it is! It brings music and news from far and wide. You
hear great men and enjoy music in your own room. This wide world now lies in
your small pocket. How small your transistor is, but how wonderful its
service is! Now you can hold the whole world between your fingers. But our
television is more wonderful still. You not only hear but also see the
whole world with your own eyes. You see people talk or sing or dance. Thus
science has conquered both time and space.
Electricity is not less wonderful.
Electricity lights our homes and streets. It gives us fire, too. It moves our
trains and trams. It runs our mills and factories. You switch on a button and
get everything. What a wonder! Even a magician cannot do what electricity does.So,
today we cannot live without science. Science gives us a new life. How easy
now is the work of doctors and surgeons! A surgeon does what even a magician
cannot. How wonderful is the work of X’-ray! Is this ray less wonderful than
the rays of the sun?But Science has produced some fearful things, too.
Atom bombs and hydrogen bombs are great wonders, no doubt, but they are also
great dangers for man.There is, however, nothing wrong with Science itself.
Science has given us atomic energy. It is a very powerful weapon. In fact, this
is the greatest wonder of science.But it is for us to use it well.
Atomic energy if rightly used can create new heaven upon this earth and it will
be more wonderful than the old heaven upon this earth and it will be more
wonderful than the old heaven created by God Himself. But if we misuse this
energy, the earth will become much worse than hell itself. It is for us to make
a hell or heaven of this earth.
