Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). Acid rain is caused by emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, which react with water molecules. Distilled water(doesn't contain CO 2), has pH level 7. Liquids with pH level less than 7 are acidic, liquids with pH level greater than 7 are alkaline. Unpolluted rain has a pH level over 5.7, so it is slightly acidic. Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan Causes · It is caused when sulfur dioxide and nitrogen oxides are released into the air. In the atmosphere they re...
Causes: *The main cause of animal extinction, without doubt,is human demand, either for animal resources directly, or for the natural resources of the animals' habitats. *In addition to that, there are other indirect causes caused by human activities. *Habitat loss: Is considered to be the main cause for animal extinction. Humans are clearing our forests for wood and timber. The foodchain is disturbed and animals will die. *Wildlife trade: Poaching and wildlife trade are another common threat to animals. International wildlife trade has also been linked to drugs trade. The most common anilmal trade is pet trade, such as orangutangs. Animals are also killed for fur(tigers, leopards, cheetahs) *Climate change: It has been recently suggested that warmer global temperatures may be affecting animals. In fact, it has been suggested that the golden toad became extinct because of the warmer climate. The Animals *T-REX: Tyrannosaurus rex was on...

ENVIRONMENTAL PROBLEM The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natu...

Stress of the Young people Today I think every young people have been faced with stress, like feeling exhausted or undrer excessive pressure. It may cause a desire to run far away from problems just because couldn't cope with it. The main thing in school age peoples what causes stress is probably school. Teachers are giving too much homeworks for not thinking that them subject is the most important. Also about half tests in one period is in the same week. The second thing I bring up is lack of funding. For young people is important hang out with friends, going to the cinema, shopping or just käia kuskil trennis. Everything costs nowadays, but if you don't have money, it causes more stress. Thirdly some young people, especially teenagers, don't get on with their family. They find that everything parents doesn't let them be independent. Some young people's parents are divorced or are drinkers. I have also felt s...

Eating Disorders It seems like every little girl dreams of becoming a model. They want to be thin and pretty like the models they see on television . Often the desire becomes an obsession and young girls see "thinness" as being a needed characteristic. For many girls, the teenage years are spent trying to acquire this look. Eating disorders are a serious health problem. Three of the most common eating disorders are anorexia nervosa, bulimia nervosa, and binge eating or compulsive eating disorder. There are other possible causes to this widely known health problem. The media shows a great deal of beauty and thinness on television and magazines that are viewed by many people daily. Everyone has the desire to look like the actors and actresses do but, in reality, it just will not happen for most of us. An unfavorable relationship a person has with others is also...

Ristna Sea Store Ristna Sea Store (in Estonian called Mere Kaubamaja) is an exhibition which was founded in 2009. It's located in Ristna. Ristna Sea Store introduces the topic of marine debris in the Baltic Sea. This exhibition includes all items which are found from the coast of Hiiumaa. All these products have came from the polluted Baltic Sea. This is where it's located. We went there with 3 of us. We took pictures and collected some information about marine debris in the Baltic Sea aswell. This is how the museum looks like from the outside. Here are our students in front of the Ristna Sea Store sign. The most common components of marine debris in the Baltic Sea are food waste and packages. 31-43% of marine debris are plastic bottles and even 50-63% of marine debris is plastic. Marine debris is harmful for everyone. It causes garbage ingestion and entanglement for marine animals. For marine life it causes accumulation and sprea...

Having a job while studying Siin on minu nimi; 11klass Siin on kool, 30.05.2012 Many students nowadays prefer to have a job while studying or the other way around study while having a job. All that, just to support their hobbies/studies, gain experience or just to earn a bit more money. While there are many benefits, there is no good without the bad. Having a job especially while you are studying is great responsibility for a human being. It is difficult to keep both your job and studies up. Although there are good points, like earning money to support yourself, gaining work or life experience, learning more about how the world works something, that schools usually do not teach.

Essay: Money is the root of all evil Vanessa Maibaum Money is the only thing you need to pay for things you have to buy. It helps to buy and sell things and pay for the services. When money is so important, then why people say that its the root of all evil. Money is also something that causes a lot of troble. For example when you have it much then some people only are friends with you because they need money. Like, they play friends with you only because they know that when they need money then they can borrow that from you. Also it causes troble too when you do not have money. Because when you do not have it you think that you are so unhappy only because you do not have money. It is because you cannot buy things you think you need to be happy. I think that, when someone thinks that they are unhappy because they do not have money, they a...
We do not inherit the Earth from our ancestors; we borrow it from our children There is a saying that „we do not inherit the Earth from our ancestors, we borrow it from our children.“ Nowadays people don not think about it and are ruining the planet. There are researches which say that the human life on Earth will go extinct within a century. Eventually the Earth will become uninhabitable. People cannot change the past but their actions affect the future. One of the ways how people are affecting the lives of future generations is increasing pollution. Clean air and water are the most valuable resources, but they are getting more and more polluted. For example the air in China is so polluted that people need to wear masks. The pollution of water kills hundreds of thousands of water animals and birds. Some of the big companies have accepted the problem and are taking action. For example M...
Smoking is on the increase among young people One of the largest issues today is underage smoking. The number of teens who smoke has dramatically risen over the past years. Smoking is one of the biggest causes of death and health diseases. Most of the youths start smoking to improve their self image with no attention of becoming addicted. The awareness of the harmful effects of smoking among young people has been rising but many of the young people ignore the dangers of smoking. One possible solution to reduce smoking is to educate the teens. Schools could have classes and seminars that increase the knowledge about the consequences of smoking. That way teens would be aware of the health problems such as many different cancers, heart diseases, asthma and strokes caused by cigarettes. Youths should also see the visuals how smoking ages skin and yellows teeth. Also a similar meetings for parents and students ...
1 Caffeine 2 3 Caffeine (C8H10N4O2) is the common name for trimethylxanthine (systematic name is 1,3,7- 4 trimethylxanthine or 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione). The chemical is also 5 known as coffeine, theine, mateine, guaranine, or methyltheobromine. Caffeine is naturally 6 produced by several plants, including coffee beans, guarana, yerba maté, cacao beans, and tea. 7 For the plants, caffeine acts as a natural pesticide. It paralyzes and kills insects that attempt to 8 feed on the plants. The molecule was first isolated by the German chemist Friedrich Ferdinand 9 Runge in 1819. 10 When purified, caffeine is an intensely bitter white powder. It is added to colas and other soft 11 drinks to impart a pleasing bitter note. However, caffeine is also an addictive stimulant. In 12 humans, it stimulates the central nervous system, heart rate, and res...
TSUNAMI Kristjan Sillaots G1R2 WHAT IS TSUNAMI? A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore. WHAT CAUSES A TSUNAMI? These awe-inspiring waves are typically caused by large, undersea earthquakes at tectonic plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly, it displaces the water above it and launches the rolling waves that will become a tsunami. WHAT CAUSES A TSUNAMI? Tsunamis may also be caused by underwater landslides or volcanic eruptions. They may even be launched, as they frequently were in Earth’s ancient past, by the impact of a large meteorite plunging into an ocean. ...
Drugs are chemicals that change the way a person's body works. You've probably heard that drugs are bad for you, but what does that mean and why are they bad? Medicines Are Legal Drugs If you've ever been sick and had to take medicine, you already know about one kind of drugs. Medicines are legal drugs, meaning doctors are allowed to prescribe them for patients, stores can sell them, and people are allowed to buy them. But it's not legal, or safe, for people to use these medicines any way they want. Cigarettes and Alcohol Cigarettes and alcohol are two other kinds of legal drugs. (In Estonia, adults 18 can buy cigarettes and alcohol.) But smoking and excessive drinking are not healthy for adults and off limits for kids. Nicotine is the drug in tobacco leaves. Whether someone smokes, chews, or sniffs tobacco, he or she is delivering nicotine to the brain. Each cigarette contains about 10 milligrams of nicotine. Nicotine is what keeps peo...
Air pollution Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Air pollution has been a problem throughout history. Even in Ancient Romepeople complained about smoke put into the atmosphere. The effects of air pollution are diverse and numerous. Air...

1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a l...

My Magna Carta. When I first started my own Magna Carta, I thought what's the most near heart and important to me. I chose two main topics, what I find important and relevant. I'm sure that I'm not the onl one who thinks like that. The first thing I would do, is forbid bullying. What is bullying? Bullying is the use of force, threat or duress to abuse, terrorize or aggressively dominate others. There are different types of victims. One of those is the one that ignores all the hate and insulting what comes at him/her. The other one takes it all by heart and seriously. Words can hurt, a lot. Most of the people don't realize what are they causing the victim, when bullying him/her. The worse cause that bullying can cause, is suicide. There is 7% of young people who attempt suicide every year. Nearly 30% of students don't go to school, because they don't want to get bullied. Also ...

Water pollution Attention for water pollution exploded in the 1980s. The oil spill of the Exxon Valdez showed many around the world just how horrible the effects of water pollution could be. However, even the Exxon Valdez spill barely touched the surface of the problem of water pollution. The ship spilt only 5% of the oil spilt that year, and oil is just one of many pollutants that people dump into the water every year. Every year, 14 billions pounds of sewage, sludge, and garbage are dumped into the world's oceans. 19 trillion gallons of waste also enter the water annually. The problem of ocean pollution affects every nation around the world. This is especially true because water is able to transport pollution from one location to another. For many years, chemicals were dumped into bodies of water without concern. While many countries have now banned such behavior, it continues to go on today. As the world has industrialized and i...
