Earth Day
On 22d
April in connection to the project “Eco - Friendly Planet… This is our Home,
Keep it Clean!” and the world Earth Day the students from Vocational school Nikola
Vaptsarov took part in a number of activities executed with the help of Miss Mariana
Kolarska, coordinator and leader of the project. The guests and the audience were in-
formed about the origin and the reasons for the celebration of that day and its impor-
tance in our lives. Read from 2 to 3 page

This is part of the story
we believe everyone
should know in order to
become involved in the
conservation of our na-
ture…
In 1969 the people be-
came witnesses to the
devastating oil spill in
Santa Barbara, Cali-
fornia. This made Gay-
lord Nelson start a
campaign for the con-
servation of the envi-
ronment and on his ini-
tiative on 22 April 1970
the world Earth Day
was celebrated for the
first time. Millions of
Americans took part in the demonstration and
insisted politicians, statesmen and the business
circles to include in their priorities the conser-
vation of the environment.
Bulgaria is one of the first countries that joined
the annual celebration of the Earth Day which
started in 1990. On 22 April 1992 the President
of the Republic of Bulgaria, Zhelyo Zhelev,
signed the oath in the name of the Earth. More
than 30 000 Bulgarian children signed the Life
on Earth Declaration. The Declaration was
handed in the UN conference for environmental
issues and development which was held in Rio
de Janeiro in June 1992.
Thence Bulgaria participates every year in the celebration of the Earth Day and gives its contri-
bution for a cleaner and healthier
environment as well as for the pres-
ervation of life on earth.
We, the students of Nikola
VaptsarovVocational school , be-
lieve that today is the day to realize
that we must not deliberately pollute
the environment, the mountains and
seas, the valleys and rivers, our
country, our town and the green
spaces among the blocks of flats,
our school and classrooms. We
have to understand that we mustn’t
drop litter wherever we want, but
only in the designed for that places.

We, the people, continuously
pile our Earth with tons of
rubbish. We find it every-
where and we don’t even
bother to think how long it
needs to decompose and will
stay in the nature. That is why
we send an appeal not to pol-
lute the environment and not
to turn it into a dumping
place.
In defense of this cause we
presented the scene where the
four natural elements: Mrs
Water, Mrs Earth, Mr Air and
Mr Fire were our guests. They
faced the public with an ap-
peal to protect the environ-
ment and preserve it the way
we took it from our ancestors,
to keep the water and air clean and to use the fire wisely.
We have to understand that we are part of the nature and it is our duty to live in harmony with it. It may
be everlasting, but it is incapable of curing the numerous wounds which we cause with our reckless ac-
tivity. We can fight the ecological problems on Earth when we change the way we think and man’s ac-
tivity. Let’s save our planet clean in order to leave something behind!
In order to support our words with deeds we cleaned the area around our school, planted flowers and
showed the environment our love and care.
The aim of the project, on which we work, is to keep our planet clean. We meet a great support in the
face of the headmaster of Nikola VaptsarovVo-
cational School , Mrs Vasilka Stoilova.
The celebration continued with songs and folk-
lore dances and ended with the song of Michael
Jackson “Earth Song” which made us think
about our existence and the planet Earth.

Nature…..
“Nature entertains the stupid,
teaches the smart, and it reveals
its interesting secrets to the
wise”
A. Einstein
Which group would you like to
join in?
Nature is a fairy tale; it is our
home, it is harmony, beauty and
unity.
For the last decades we have been
trying to harm and destroy it
rather than keep it safe.
This process reflects on us too,
the way we think is the way we
create our reality.
We can change things for the bet-
ter.
First of all, we need to see na-
ture’s beauty and understand it.
This happens to every man in a
different stage of his or her life
and it is a matter of man’s point
of view, and you should believe
that it can motivate us to create
true beauty in our everyday real-
ity.
What could be better. It is “the
key to life”, “a sorceress filled
with the most vital power of life
and spirit”.
The nature is a conglomerate of
sun, air and water, mountains and
forests…It inspires, brings pleas-
ure, amuses, brings aesthetic
pleasure which makes us feel de-
lighted and stand in awe.
It is in the nature where we find
inspiration and relax…
Being in an abiding admiration
from its sceneries, we can rein-
carnate it into our themes of life.
It is extremely important for our
way of life. Nature cures every-
one with herbs, the aroma of the
flowers and the freshness and pu-
rity of the air. It pours vital cur-
rents into plants, animals and
people.
In the century of nuclear plants,
computers, Internet, wild and
giddy music and disharmony, the
nature can hardly resist such raids
of nightmares…the forests which
astound us with their colour and
vividness are the most powerful
generator of air. They serve as
coordinators of the rain clouds.
Every plant is like a medical bot-
tle of oxygen which generously
releases pure and fresh oxygen.
Now the forests are sad, you can’t
hear the sweet songs of the war-
blers. What you can hear there
now is the noise coming from
wood chippers and the falling of
beautiful giant trees – the pride of
the forest’s nature. An almost
burned down cigarette thrown
away carelessly can start an enor-
mous fire and devastate wide for-
est regions. The forests are a
priceless bio centre for the human
health, so every damaged tree
affects the environment. They
give shelter to many different and
beautiful animals…The decision
whether to ruin and devastate or
to build our surrounding world is
in our hands.
If we choose to ruin and devas-
tate the nature, it will destroy our
human environment…But if we
take care for it every single day,
it will allow us to develop and
become richer both literally and
metaphorically..
These are several things we can
do every day:
We need 15 to 30 min every day
to help saving our planet Earth
just changing some things in our
everyday life. We can’t stop the
climate changes, but at least we
can choose a way of life which
doesn’t help increasing these
changes and helps protecting the
environment.
If we make a wise choice for our
way of life, each of us can give a
good example to the others.
These are some simple things
which you can do for half an hour
or even less to help protecting our
planet. They won’t change your
life in a drastic way, but they will
be extremely helpful.
Eat more fruits and vegetables.
Eating more fruits and vegetables
than meat can help the environ-
ment more than you can imagine.
The extensive consumption of
meat and dairy products helps
global warming because for the
animals we breed for food there
are more greenhouse gases re-
leased than there are when we
grow plants. Breeding animals for
food needs huge amounts of soil,
water, grains and fuel.
It doesn’t take more time to make
a salad than making a hamburger
and it is the better option for you
and the environment. During the
week you can replace several
meat meals and at the same time
to help yourself and the environ-
ment…

Walk or ride a bike for shorter dis-
tances and choose the public trans-
port for the longer ones.
You will be surprised what distance
you can walk on foot for half an hour.
Calculations show that the people who
walk on foot to work for example are
much healthier than those using trans-
port for the same distance.
According to latest researches if the
members of a family use only the pub-
lic transport or walk on foot, for one
year they can save money enough to pay their yearly expenses for food.
Use reusable bags
The use of reusable bags significantly reduces the amount of generated rubbish. Most of them can be
folded and become small enough to have them with us. So they will be close at hand when we go shop-
ping. Reduce to its minimum the use of plastic bags. A lot of energy and resources are used for their pro-
duction and there are many harmful substances issued from this production. After being used they be-
come rubbish, pollute even the water reservoirs and are responsible for the extinction of thousands of sea
mammals. Speaking worldwide there is about 1 trillion plastic bags used and thrown away every year, or
this is more than a million for just a minute. The good thing is that there is an alternative – the paper and
the reusable bags. They are made from materials which do not harm the environment during their pro-
duction, the use and after they stop being used.
Replace your electric bulbs with energy saving bulbs.
Replace the ordinary electric bulbs with energy saving ones. Thus you will save money and the time you
need to change not working bulbs and will reduce the usage of energy. The energy saving bulbs are ten
times more durable than the ordinary ones and you can lower your electricity bills using them.
According to a research if every household in the USA replace just one ordinary electric bulb for an en-
ergy saving one, it will reduce the emissions of greenhouse gases as much as it can be done when you
stop from usage 7,5 millions cars.
Use less plastic items.
Switch of the lights when you’re not in the room.
Recycle your old appliances.
Buy more “green” products…don’t buy goods you don’t really need.
Use natural products like vinegar, lemon juice and baking soda to clean your homes.
Buy in bigger packages to lessen the rubbish you generate.
Use recycled paper…Print as less as possible. Use again everything that is possible.
Take part in initiatives that are connected to protecting the environment.
Pay your bills online.
A lot of banks and companies for paying the electricity, water and other things offer their clients the op-
tion to pay their bills online which makes it unnecessary to print notes and invoices. In this way you
save time, money and paper, consequently you reduce your contribution for the deforestation of the for-
ests and the global warming…

Basic Polluters
We usually don’t think about the basic polluters of
the air which are all around us and the fact that we
constantly live in that environment. That’s why if
we don’t restrict their influence in our lives, we
seriously risk harming ourselves and destroying the
planet. The pollution of the air means the introduc-
tion of new, untypical for the atmosphere chemical,
mechanical or biological substances and the change
in the average annual concentration of these sub-
stances. These substances cause serious damages to
the living organisms or these are damages affecting
the environment. The pollution of the air becomes a
matter of importance, starts playing an important
role and causes a serious influence after the Indus-
trial Revolution and we unprecedentedly must
strive to avoid it.
Let me remind you some of the substances which
are the most frequent polluters of the air:
Carbon dioxide is a gas with no colour and with
a slightly sour smell and taste. Compared to
the carbon oxide the carbon dioxide dis-
solves very well in water.
Carbon oxide with the formula CO is a gas with
no colour which is toxic. It is obtained from
the incomplete combustion of coal, methane
and wood. Cars also produce carbon oxide.
Hydro carbonates
Aldehydes
Radioactive substances and heavy metals
Sulphur dioxide – the sulphur dioxide is a gas
with no colour with the following formula
SO2, it is the product from volcanic erup-
tions and different industrial processes. The
sulphur dioxide is usually obtained with the
burning of coal and oil. The further enrich-
ing with oxygen and reactions lead to the
obtaining of H2SO4 (sulphuric acid) and
acid rains.
Nitric oxides and especially the nitric dioxide
with the formula NO2 is a poisonous gas
with a sharp suffocating smell and brownish
-red colour. It dissolves very well in water.
According to the region the main polluters in Bul-
garia are dust, sulphur dioxide, nitric oxides, lead
aerosols, ammonia, phenol, hydrogen sulfide and
others. And because the greater part of the indus-
trial activity is concentrated in Sofia as well as 17%
of the population lives there, the level of air pollu-
tion is very high.
The reasons which influence this pollution are:
The rapid increase of the population on Earth, the
scientific and technological progress and the ar-
mory has radically changed the situation on the
planet for the last 100 years.
Basic sources for the air pollution:
Among the polluters there are natural sources
too which we can hardly avoid, these are
namely:
Volcanic eruptions
Mineral springs
Forest fires
The process of decomposition and the breathing
of men and animals
The processes under the surface of the earth
Among the polluters the most dangerous ones are
those which are a result from human activity. Their
restriction lies in our hands. That’s why we can
avoid at least part of their application in our lives.
Some of them are:
Motor vehicles – cars, planes, boats
Power plants, plants, factories and other indus-
trial enterprises
Burning wood for heating
Petrol stations
Organic waste which release methane
Chemical, biological and nuclear weapons
Nicotine
Heating
Influence on the environment
The carbon oxide is poisonous and when breathed
in huge amounts it causes suffocation and death.
The sulphur oxide and the nitric oxide are poison-
ous too. The carbon dioxide in huge amounts ham-
pers the breathing of men and animals. The accu-
mulation of this gas into the atmosphere leads to
the overall warming of the planet (greenhouse ef-
fect).
7. page 7 Eco-Friendly Planet 10 June 2013
In the cities with a lot of traffic and the places where fuels
are burnt there are huge amounts of carbon dioxide, carbon
oxide and other gases and polluters in the air. These sub-
stances are a threat for the human health.
Air polluted with nitric oxide and sulphur oxide dissolves
very well in the tiny
water drops which
form the clouds and
which causes acid
rains that affect the
plants, corrode met-
als, destroy build-
ings, rocks and
monuments. When there are such rains over rivers and lakes
part of the animals there die.

Welcome to Bulgaria!
Today we will have a close look at the Rhodope mountains.
We, the students of Vocational school Nikola Vaptsarov, take part in the different clubs from the
extracullicular forms of education in our school. In connection to the activities we do we visited one of
the most beauiful Bulgarian mountains – the Rhodope mountains. We saw interesting regions and
landscapes about which we are going to tell you about.
We visited the village of Bachkovo which is 7 km away south from Asenovgrad. There is located the
second largest monastery in Bulgaria – the Bachkovo monastery. The monastery is famous and valued
for its unique combination of Byzantine, Georgian and Bulgarian culture which are united by the
common religion. We learnt that the monastery was founded in 1083 by the prominent Byzantine
general from a Georgian origin Gregory Bakuriani.
We visited the resort Pamporovo. There is the Snezhanka peak which is 1926 m high. There is a
television tower on the top with a height of 156 metres which soars to a height of 2082 metres. The
view that revealed itself from there was awesome and hardly to be described, that is why we
recommend everyone who visits Bulgaria to climb Snezhanka peak.
We had a sightseeing tour in Smolyan and found out that this city is really amazing. Its geographic
location and its function as a centre of the towns and villages in the region determine it as the heart of
the mountain. Smolyan is the biggest city in the Rhodopes and the longest in Bulgaria. The Cherna
River flows along the city. The river springs from the highest peak in the Rhodopes – the Perelik Peak
(2191m).
We visited the well known and the biggest planetarium in Bulgaria. In its „heart“ there is a round star
hall. There is a projector in its centre which creates an artificial sky which is a copy of the real one. The
projector visualised right infront of our eyes the movements of the celestial bodies: the Sun, the Moon,
the planets and the other astronomical objects and phenomena. The effect was astounding. For 45
minutes we were illuminated by the beauty of the sky which created the feeling that we have the space
on the board of a spaceship.
We passed through the Yagodinska Cave which is 10 km long and is located on three floors. There is a
1100 metre long path for the tourists. The entrance and the exit are artificially holed tunnels. The cave is
unique with its innumerable stalactites, stalagmites, stalactones, hangings and leopard skins…

Welcome to Bulgaria!
Some of the forms in the interior remind
of Santa Clause, Snow White and the
seven dwarves, the Holy Mother and
Christ, Pizho and Penda and other fantas-
tic creatures. We learnt from the locals
that there are different animals that live in
the region among which are the bears
which live freely in the forest and it is known that peo-
ple have seen them.
On the way back we saw one of the biggest lakes in
Bulgaria, the Dospat Reservoir. It is on 1200 m alti-
tude and spreads on a territory of 18.3
km2
, it is 19 km wide and 1 km long.
The beauty of the Bulgarian nature is
beyond description, but man can be con-
vinced only if they see it with their eyes.
