Air pollutions are major causes of global environmental danger such a ozon lair, acid rains or greenhouse effect. sulphur dioxide, nitrogen oxides, dust are most ofen air pollutions.
Air polutions are gas, liquid or solid that are in the air in number more that average. there are natural pollutions such a pollen or volcano dust and pollutions that are made by man for example exhaust fumes, industrial fumes. polluted air can damage human, annimal or plant body but also water or ground. Air pollution are most dangerous from all of pollutions because they are moving because of wind and can pollute big area in short time and damege all parts of environment.
sources of air pollutions: there are 3 major
1. Big industrial plant that emit dust, carbon dioxide, nitrogen oxcide, heavy metal.
2. Houses pollutions for example burning trashes, house products, aerozol cans, fridges that emit CFC's
3. Traffic pollutions from cars, planes, trains, buses for example carbon dioxcide, lead, nitrogen oxcide

E-mails or letters-which are better?
That question is the most interesting one, since the Internet was invented. E—mails are very modern way of communicating. It is used by millions of people all over the world.
First argument for writing E-mails is a fact, that we can send and receive them at the time which suits us. What is more, we do not have to worry about formal style- we can use many different, sometimes funny abbreviations, for instance 4u (for you) :-D
Last but not least: you know immediately what is the topic of your mail, reading a Subject Box.It helps very much, especially whem I'm too lazy to read the whole message.
Naturally, there are some minuses. First one, which involves many people: not everyone checks their mais regularly, so there's a possibillity that they may misss an important message. I also used to check my mailbox twice a month, when i did not have a broad-band connection to the Internet.
Secondly, nobody cares about correct spelling and punctuation..Sometimes it gets on my nerves.
Not only these features are the worst.in my opinion mails are not usually worth saving, whereas you can keep letters and look at them later.
On balance, I would say that mails and many other Internet communicators, like GG or Skype (the best one) can easily replace popular letters or phone. And that's the way the Internet comes to power.

Ten years ago, e-mails were not very known in our homes, but only in bigger Companies. Our grandmothers, aunts, even mothers communicated with people from other cities by letters. So why now, in XXI century, we - young people, do not know what is better? Let's see.
Time is very important for us, sometimes we haven't got it too much. We can send an e-mail at a time which suits us. We do not have to worry about formal style or grammar. Next argument is that we know immediately what it is about from the `Subject' box. We can also send a movie or mp3 in e-mail like an attachment. However not everyone checks their `Inbox' regularly so they may miss an important messages [sometimes we can unfortunately delete messages]. And nobody cares about correct spelling. How we hate reading wrong written messages.
Although almost everyone has Internet, letters are not dead. It is so nice to open a drawer and find old letter from best friend or family. We also learn how to good write in our language, develop spelling. And there is one important point, letters will not die, never, because people will remember about them. On the other hand, we have to write very clearly so that our friend could read what we had written before. Than we have to go to a Post office, to send it. And we know, how lazy we are.
On balance, I would say that e-mail is a good invention, nevertheless letters are very old form to communicate with somebody else from other city, even country. E-mails will never replace traditional letters. They are just another electronic newness.

A generation gap is a popular term used to describe wide differences in cultural norms between members of a younger generation and their elders. It is some kind of inability of both the young and the old to comunicate with each others. In my opinion generation gap is a very common phenomenom nowadays.

First of all, I think that nowadays, at the turn of the century the generation gap has a great background to flourish. The XX century was a period of changes in all area of life. Our parents and grandparents, who has grown up in totally different surrounding, cannot have the same outlook on life as we. Differences in lifestyles, moral norms, outlooks, aims and dreams cause conflicts between children and their parents or grandparents.

Secondly, I believe that generation gap is inevitable because of age difference between generations. It is impossible for teenager to have the same outlook on life as middle-aged or elder person. Adults cannot understand youngish giddiness, recklessness and carelessness. Also our youthful problems appear to be insignificant for adults.. That cause disagreements commonly called the generation gap.

On the other hand, it is commonly said, that XXI century is a time of tolerance. Some people claim, that nowadays parents are more modern, their attitude towards children changes. And in my opinion it is easier to avoid conflicts with adults when our relationships with them are based on friendship like nowadays. It would be hard for me to live with my parents and, like it was common in the past, feel towards them only reserved respect. Friendly and closer relation with parents helps to avoid generation gap.

To sum up, I think that generation gap is something that has always arisen and will arise between younger and elder generations. No matter how we try, it will always appear in every humans life. But we may take this triffling conflict with a pinch of salt, to be more happy and to recall it in the future with smile.

We observe violent development of technology all over the world. It influences live style of contemporary human. I consider that the more human take advantage of development of technology, the more change into `coach potatoes'. However, if human makes use of technology novelties in moderation, he won't become indolent person.
First of all, the improvement of the motorization causes that many people begin to go by cars everywhere as well to the nearest places such as shop or bank. People less walk for the reason that they don't want to become tired in walking.
Furthermore, many movies are screened in television. Watching films in television substitutes for reading books and going to cinemas or theater because of that people lead settled and unsociable live style. Additionally, movies don't develop imagination as greatly as books.
Moreover, children prefer to play computer games rather play outside. Therefore, they less move and spend spare time outdoor.
On the other hands, if people go by vehicles, they will have more time. Saved time can be used for active rest by play games outdoor, or for intellectual occupation, such as reading books.
In conclusion, I am of the opinion that modern inventions change our live. We lead more settled live style and we spend less time open-air. However, if we organize time well and rest actively, we won't become `coach potatoes'.

Many people do not like when somebody is smoking close to them but some think that it does not matter. So is that a good idea to ban smoking in public places or not?
To start with, cigarettes smoke may disturb other people. When a non-smoker person is compelled to breathe in smoke he or she may cough. Moreover clothes of non-smokers can smell badly when somebody is smoking. Secondly the smoke from cigarettes is harmful. It can cause diseases and annoy the respiratory system. An additional advantage of a ban on smoking in public places is that there will not be any remnants of cigarettes. It would be cleaner.
On the other hand, it is impossible to obey this ban by everybody. Few people will leave public places to smoke. But if they do not do it they will break the law. Furthermore, there will be no place where a smoker could smoke without breaking the law. What is more if workers leave their work places to smoke somewhere they may lose their jobs. Finally lots of people smoke and the other should respect their rights. Some diners have a special division for smoking and non-smoking comparments.
Taking all this into consideration there should not be ban on smoking in public places. A good solution is to share places vor non-smokers and smokers. If we ban smoking in public places we will break smokers nights.

Each man sometimes thinks about money- in good or bad ways also. The vast majority of people perceive money as very important and want to be rich. And as far as having a lot of money is concerned- people have many various opinions, as well.

There is no denying that being rich has number of advantages. First of all, rich people can do everything they want. As a result, they do not have to control their expenses- they can afford to travel, enjoy, buy a huge house etc. Moreover, one very convincing argument in favour of having a lot of money is that you can help some charity organizations. Another positive aspect, especially for young people, is that they can study wherever they want and still not worry about the payments.

On the other hand, money not always bring positive things. A good example of drawbacks is it that we cannot buy happiness and health. Furthermore, money does not solve all of our problems. In fact, everybody dreams about having enormous amounts of money, but do not think about implications. Many rich people are divorced and (or) addicted to drugs, alcohol, gambling. What is more, rich people are never sure if all the friends around them are real ones.

On balance, it seems that having a lot of money has as many positive aspects as negative sides. In conclusion, all the people can have benefits from being rich as well as bad points. The decision remains only a matter of personal choice.

From nineteenth century progress in technology and science was very significant. Many inventions such as: stream locomotive, electricity or telephones were the revolution in the development of industry. The use of modern engines and different devices enabled us to accelerate production and manufacturing. Work, in factories, become easier and more comfortable. Households were also upgraded. Many domestic appliances like: washing machines, vacuum cleaners, fridges, dishwashers and many other useful objects appeared. During twentieth century, after the Second World War, a lot of modern equipment was used in our households. Colourfull TV sets, consoles, camcorders, video recorders, mobile phones - these inventions made our live easier and more pleasing.
Nowadays, we use all the equipment everyday. The majority of us probably cannot imagine life without mobile phones or sound players. Presently, we can communicate with other people all the time. World Wide Web may be used to data transferring on very long distances. From several years, web's users do not have to be connected with network cables. We can use wireless access from satellite with the use of suitable modems. Today, people do not get lost easily, because a lot of useful equipment can always help them. Global Positioning System always shows you where you are, and how to get into nearest orientation place like mountain, river or valley. GPS is also used by drivers, who often use it to find the way to nearest petrol station, parking or restaurant. A lot of people like: businessmen, politics or clerks must keep in touch with their offices and companies. The easiest way to communicate with other people is to move with notebook or palmtop with wireless access to network. Then we can talk, write, transferring data wherever we actually are. E-mailing, video conferencing or speaking with our colleagues and stakeholders was never as easy as it is nowadays.
Modern technologies also concern entertainment market. Everybody want to have a fun. Producers want to amuse all the customers, so they offer different equipment for them. We can for example buy a console to play in the majority of games. Hardware like Xbox or PlayStation may relax the player. Some kinds of games, I mean strategies and Massively-Multiplayer Online Role Playing Games require PC to use. Unfortunately, they are very time-consuming, so not everyone can spent time playing them.
Overall majority of people like going to the cinema and watching films. We can watch them differently. The image can be displayed with the use of projector, Liquid Crystal Display or Cathode Ray Tube. The films are often displayed on large surfaces. The diagonal of plasma TV sets is often greater than one hundred inches. It is about two meters - wide television. That makes a good impression! If somebody wants to hear the surrounding voices around himself, he can mount speakers that consist of five or seven `satellites' and subwoofer. Then all sounds will be more realistic and natural. Using the suite like that should satisfy each human being.
A lot of people love to commemorate their life. Today, we can buy different digital cameras and camcorders, with the use of which we may easily document important occasions and incidents from our life. Christenings, holy communions, weddings, birthdays and other meaningful events should be recorded and kept as memories from the past. We ought to save the memorials of our families for the next generations. Cameras can be also used to keep in mind all the souvenirs from trips and travels. All interesting places and people can be recorded and photographed. The beauty of natural environment, landscapes, monuments, works of art or unusual architectural constructions can be saved on photos and videos.
All of above-mentioned inventions are very useful and helpful in everyday life. We use them and we do not care about world which surrounds us. We can forget about everything, and enter virtual world. In my opinion, all `diseases' like net or games addictions are harmless and unthreatening for the society.
Without modern technologies life on the Earth would be much harder and not very friendly for its inhabitants. The majority of inventions makes our everyday activities like: cooking, cleaning or ironing much easier. We should have much more time for us, but in fact, our time is gobbled by TV, games and other enjoyments. However, expansion and development of technologies was very meaningful for science, medicine and economy. According to famous saying: `Time and tide wait for no man' everyone is pushed for time, nobody can stop and think about himself. Peoples from twenty first century have not much time, that is the fact, but let's face it! Without advanced technologies we will be probably using abacus to calculating and bucksaw to amputation of the limbs.

I think our planet is much polluted. We should blame ourselves, because we are making Earth sick. Because of factories and cars air is polluted by smog. People often throw out litter not into trashcan but for example on ground or even in rivers or forests. Industrial wastes are pouring in oceans and seas. So, it's normal that fish and birds dying when water isn't clean enough and air is polluted.

Big corporations don't care that they cut down many trees year after year. They don't care because this is the way for easy cash. Fabrics fume give off many fumes, so often take places acid rains. Organizations like Greenpeace try to stop them, but today always win who has much money.

Freon destroys ozone which protects us from harmful radiation. In effect ensures global warming. So we should take care and do not burn aerosols. Batteries and accumulators should be segregated, because they are polluting soil.

Moreover many animal species are endangering, because we are destroying their natural environment.

In my opinion we should start to live ecological. For example we should segregate litter - glasses, papers and plastics, buy only those products which can be recycled and energy-efficient. Moreover you should turn off electrical devices, if you don't use it. If you want save water, you might have a shower, not a bath. It is a good idea to build nature reserves and protect tropic forests from cut down.

Human race is the worst living specie, because it destroys everything and don't try to live in symbiosis with other species.

Until the 1960s, London was a very polluted city. Factories poured their waste liquids into the River Thames. There were no fish and it was even dangerous if you fell in. People burned coal to heat their homes and the smoke polluted the sky. In winter, the smoke often combined with fog to create smog, and many people died of breathing problems.
But since then, new laws have stopped people polluting the rivers and the atmosphere. They've made the river much Cleaner fuels are used for heating, and there hasn't been smog for years.
However, like in all cities around the world, traffic in London is growing and causing more and more pollution. The most serious threat to every country in the world is global warning. Gases like carbon dioxide from power stations or traffic go into the atmosphere and trap the sun's heat like a greenhouse. The average temparature all round the world has risen by several degress over the last few years, and there is a risk that the ice caps will melt and the sea level will rise, and there will be floods in many countries.

After a long and tiring day at school I like to spend my free time in such away that I feel relaxed. The kinds of activity I choose depend upon the time of the year. When it is sunny and warm I go out. When it is cold, rainy and dull - I stay at home. In the summer I ride my bicycle. I like to go to the forest, where the air is fresh, but sometimes I ride round the city to see if something interesting is going on. Usually the bicycle trips take me about an hour. Also, if it is warm I use my bicycle when I go shopping or go to visit some of my friends. I often visit my friends and I like them to visit me. As we always have something interesting to talk about, we never get bored with each other. My friends and I often go for walks and it does not matter if it rains or the sun shines. Going for long walks and cycling are favourite outdoor activities of mine. Late in the evening I like to read books or magazines: Reading takes most of my spare time during the long winter nights. Someti¬mes I play computer games. But I do not spend much time in front of the TV screen. I am also interested in films and the theatre. I do not have any manual skills, so I neither draw nor paint. It seems that I am quite a busy person. I am, indeed. But sometimes, after a busy day the best way of spending my free time is just lying in bed, doing nothing.

My name is joanna. I was born on twenty sixth of May. I am 24 years old. I have economist education. I am a student of sociology in TWP in Olsztyn.
I like to ride a bike, walk and in the evening surf the Internet. Late evening I like watching films from the Bollywood.
I have straight, blond hair and grey eyes. I am an sociable person, optimistic and positive thinker. I?m very good at reading stories, cooking.
I am married. I live with my husband, Mark, my son Jacob and daughter Veronica in Warsaw. We?ve got four dogs Rachel, Anares, Axel and Domenica. Two amstaff, French bulldog and Chinese mane (chiński grzywacz).
My husband is twenty nine years old. He is an engineer. He works in building inspection. He has got short blond hair and blue eyes. His favorite actress is Monica Belluci. Mark likes photos and play volleybay.
Jacob is two years old, but he?s very clever for his age. He loves playing football. He has short, fair hair and big grey eyes, just like me.
Veronica is four years old. She likes to play computer games and she goes to forest. She has got short, fair hair, grey eyes, and a beautiful smile.
We all like dancing very much. We?re all very happy with our family life, and we would love to shae it with someone.

People are discavering more and more new things in order to make life easier and more carious. This what is useful brings us happy. Technology expansion influences on relation between people and shows us new possibilities.
Duties which were earlier done by humans now are done by a new machine e.g computer,robot,autamat.
Peolple stop create things which they are use. Clear progress in medicine, use new technologies to diagnose and combat diseases make therapy more effective. Statistic show that life expectancy is getting longer.
Also a very important is communication which is the fastest developing part of technology. Not only cars and aeroplanes but also the internet and phones are now inseparable part of human`s life.
Thanks of them our life is more comfortable. Ambulances and phones help to rescue people, also fire brigade can arrive faster to the place in fire.Besides, phones give us a better contact with our family, friends and other pepole.
I think that this big progress has made our life better and more carious and comfortable but the world isn`t better. In the enviroment is a lot of pollutions the crime rate is high and the only one thing what people care about is money!

good and bad things about computer

Computer technology has its advantages and disadvantages. It seems to me that there are more bad things than ones. The bad things is that to use computer and internet we have to pay a lot of many. We also have to change parts of it to somethings. Upolate it because computer technology devilopes. Like hard disk, mouse pad and keyboard. The bad thing is that we spend too much time indoor playing computer games and surfing the net, and then our eyes get weeker. There are many more bad things, but there are good things too. One is that we can find things which are important for us. There is laptop and we can take it everywhere we wont.
Internet is a good and bad thing. It is bad because there are pornographic websites, we can get e-mail error with spam and then we can throw away computer. Good things is that we can look for information, and we can play games but there is one more thing about internet we have to pay for it.
