Teacher:

Good morning! We welcome you at our lesson-conference “The influence of the ecological factors on the health of people”. You know, that 2017 is declared to be the “YEAR OF ECOLOGY”. Our conference is dedicated to it.

There are many participants at our conference. They are students, teachers, guests, specialists in different scientific fields: ecologists and doctors. The aim of our conference is to find out how environment factors help us keep our health. Besides, we are interested in the ecological problems which worry all the humanity.

Let me introduce our guests- Dr. Addison, Dr. Cooper, Dr. Wright, Dr. Chester from Brighton.

Our specialists are- general practitioners, cosmetologists.

According to the conference requirements, we should elect the Chairman and the secretary.

Our suggestions are- 

To begin with, let’s speak about our favourite town. We live in Anapa. It is situated on the Black Sea coast. It is famous for its climatic factors. The climate of Anapa is mild, humid and warm. Anapa is one of the sunniest spots on the Black Sea coast. There are 280 sunny days in the year. Anapa is not only one of the beautiful cities; it is one of the famous resorts In Russia.

At your lessons of biology you’ve spoken about the human’s body, different systems of it. We got to know that our health depends on all system’s functioning. What influence do the environmental factors have? Let’s ask our guest Dr. M Taran from Russia.

 Student 1

A man can live without food for some weeks, without water- some days, but without air- only some minutes. All nutrients in our organism are stored as the water, but fresh air reserve is limited by lungs volume

Medicinal features of sea air are connected with microelements, which are dissolved in the sea water. It’s wonderful that there are practically all the elements of Mendeleev’s classification system.

 Student 2 Medicinal features of sea air are connected with microelements, which are dissolved in the sea water. It’s wonderful that there are practically all the elements of Mendeleev’s classification system.

The first sanatorium was built on the “high shore” according to the recommendations of Dr. Budzinskiy.

Teacher:

When the first ancient people came to the seashore and settled there, the humanity fate was closely connected with the sea. It must be mentioned that the sea as the fire can cruelly punish everyone who scorns the danger of its force and power. But if we treat the sea properly and take care of it, it can benefit all the inhabitants of its shores.

Student 3 (Dr. Addison) Last year British scientists from Devon and Cornwall made a research. The aim of the research was the connection between British people health and remoteness of their settlements from the sea. People who live 50 km from the sea (in Leeds or Sheffield) say that their health is not as good as the health of people who live 5-50 km from the sea. The healthiest people live 5 km from the sea .Besides people are wealthier if they live in the coastal towns and cities

But not only sea air is useful for people. Sea water influences our organism greately.

 Student  4 (Dr.Cooper)

Sea water is strength and energy, life elixir. Sea gifts – sea water, salts, seaweeds are unique medicines for people.

Sea water is a natural solution. Its salty taste depends on salt quality. Its bitter taste is formed by chlorine magnesium, sodium sulphate.

Sea water was used for treatment from the time immemorial. In ancient Egypt doctors recommended it as a medicine to cure stomach, blood deficit, etc. It was used to wash the wounds. It was the beginning of thalassotherapy.

Dr.Addison.

The founders of the thalassotherapy were the British people started havig a rest on the sea coast after Dr. Richard Russel had published his work “Dissertation about sea water benefits in tonsils treatment”. It happened in 1750.  The discovery of useful features of sea water provoked the real overcrowdings in town resorts. Many years ago he moved to the small Sussex village Brightelmstone to start a new resort. 10 years later it became a flourishing town resort, called Brighton. In 1820 the Royal pavilion was built in the resort.  The population became 24 thousand people. Sea water beneficially influences our nervous system, which controls all organs.

Sea is a natural psychologist and psychiatrist. Wave noises, horizon views always improve our mood, take out our nervous tension, cure our depression and make us optimists.  Rhythmic waves, sea breakers calm us and help control our insomnia. 

Student 5 (a cosmetologist)

It’s interesting that the sea salt has wonderful cosmetological features. It stimulates the regeneration of tissues, improves skin elasticity, and cleans the skin cells and help with the cellulites. It also makes our hair stronger and promotes waste removal and withdraws oedema. Besides sea salt benefits our nails, they become stronger and grow faster. Swimming in the sea is the best procedure for fragile (brittle) and stratified nails.

Moreover, sea salt quantity in one liter in different seas is various. For example, in the Baltic Sea there are 7 grams, in the Azov Sea- 11 grams, in the Caspian Sea- 14 grams, in the Black Sea- 18 grams, in the Mediterranean Sea- 38 grams, in the Red Sea- 42grams, in the Dead Sea- 270 grams, in the World Ocean- 35 grams.

Cosmetologists consider that half an hour swimming in the sea is equal to the massage because sea waves are the best training apparatus for the circulatory system. Blood vessels narrow and blood rushes to the inner organs. Furthermore, waves are the natural hydro massage which helps muscles be vital, make flabby skin stronger and improves blood circulation. Water temperature is lower than our body temperature, that’s why it increases heat exchange. Our organism loses a lot of energy even during passive being in the sea water. For overweight people it’s the best opportunity to lose weight. Bear in mind, it’s better to swim 1, 5 hour after the meals.

Teacher

Anapa as a town resort is unique, but not only the ecologists are worried by the ecological situation of the region.

Student 6 (an ecologist)

By the end of the XX century ecological situation of the Black Sea was defined as a crisis.

Actually, it can’t help worries of the world community. It’s especially awful for people living at the seaside, because the Black Sea itself is their home, the source of their vital activity.

Millions of people from different regions and countries come to the Black Sea coast to have a rest. They have rights to enjoy the natural beauty of the sea without any risk for their health. Water pollution is one of the risks.

Speaking about ecological problems of the Black Sea we can define the following :

-         eutrofication (water flowering) remains because of chemicals. Besides there are not enough purification systems;

-         water pollution by oil products and other toxic substances;

-         biological pollution by scallops and coquina (Rapa whelk) ;

-         decrease of the biological variety, disappearance of some species of flora and fauna;

-         decrease of the natural landscapes, forests and sanctuaries in the coastal zones ;

-         accumulation of solid wastes.

Student 7:

 The biggest damage to the sea species is done by nitrogen and phosphorus compounds from consuming and industrial wastes and rainwater. The biggest quantity of these substances comes from the rivers. Nowadays phosphorus is one of the components in different detergents, that’s why, it’s quantity increases, too.

Student 8

According to the statistics of the International Association of tanker’s owners, the Black Sea is the first in oil pollution in the 21^st century. Oil goes into the environment in the result of planned or emergency wastes from the tankers and ground springs.

It’s awful but the bottom of coastal water areas is full of rubbish (bottles, plastic wastes, fishing nets, etc.).

In the sea water any rubbish is decomposed during years, decades, but the plastic wastes are decomposed during centuries. Toxic products of decomposition go into the water. It is also dangerous for all the sea animals, because they swallow these plastic wastes and even (sometimes) die.

Student 9

Океан седой гремит набатно,

Он таит обиду в глубине,

Черные раскачивает пятна

На крутой, разгневанной волне.

Стали люди сильными как боги,

И судьба Земли у них в руках.

Но темнеют страшные ожоги

У Земного шара на боках.

Мы давно освоили планету,

Широко шагает новый век,

На Земле уж белых пятен нету,

Черные сотрешь ли человек?

 А. Плотникова «Черные пятна»

Teacher:

Let’s discuss a problem “What should I do in order to protect the environment?”

Some of you can write your suggestions on the lists of paper.

The secretary:

Resolutions:

1.     After visiting the seashore we should take out all the rubbish (even if doesn’t belong to us).

2.     We should try to save water in order not to overcharge purification systems.

We shouldn’t pour oil, paints and chemicals on the ground or into the sewing system.

We should utilize them not to damage the environment.

3.     Demand administration to pay attention to ecological problems.

4.     Make state municipal organs, responsible for ecology, carry out their duties properly.

5.     People should be interested in all the construction works near their houses in order to control their influence on the environment.

Conclusion:

So, today we have spoken about sea air and sea water influence on our organism, about ecology of the Black Sea and our Anapa. Let’s make up a poster for their keeping safe.
