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
The environment in realtion to mobility/transport in Europe Air pollution is problem all over the world. Through some pollution comes from these natural sources, most pollution is the result of human activity. The biggest causes are the operation of fossil fuel- burning power plants and automobiles that combust fuel. Combined, these two sources are responsible for about 90% of all air pollution in the United States. All kind of pollutions can lead us to serious health problems. For example, air pollution is increasingly being cited as the main cause of lung conditions such as asthma - twice as many people suffer from asthma today compared to 20 years ago. Every year, 3.2m Europeans are diagnosed with cancer - the most common cause of death after heart disease. Most widespread are cancers of the lungs, breast and colon

Genetic modification of food results in increased toxins and diseases as genes from an allergic plant can transfer to target plant. Genetically modified crops can cause serious environmental problems as an engineered gene may prove toxic to wildlife. Another drawback is that increased use of toxins to make insect resistant plant can cause resultant organisms to become resistant to antibiotics. FIND OUT 5 REASONS TO AVOID GM FOOD.

Although it’s true that we cannot physically stop our ozone layer from thinning there are
air that we breathe, becomes dangerous to our health. The ozone layer around the Earth, there is a special type of oxygen called ,,ozone". Ozone is important because it stops ultraviolett radiation from the sun. Many aerosol sprays and factories destroy ozone and they have made a very big hole in the ozone layer. This means that too much ultraviolet radiation now enters the Earth. This is very dangerous because it can cause cancer. Poisonous chemicals also cause acid rain, that destroyes plants, rivers, lakes and buildings. Acid rain can travel thousands of miles, so pollution in one country can become acid rain for another country. So how to avoid the worst? Lets talk about cars, which are the main means of transport in our everyday life, they are useful and take us to the place, where we want to go. But lets be honest, they have also negative aspects.

Taking up cycling instead of using a car is too dangerous in cities. It could be argued that taking up cycling is very healthy for people. It supports people more to move and it is like doing a sport. Besides it is very good for environment. Thanks to using bicycles cities air will be cleaner and air is not such impure. Thanks to cleaner air people's can breathe better air. This is partly true, but taking up cycling instead of using a car is really more dangerous than use only cars. Thanks to taking up cycling traffic will go busier and messier. There is much different kind of movers in traffic and it makes traffic really dangerous. It is clear that it is not too dangerous. There are many cities where cycling is very popular, for example in Copenhagen
to Les' habits. USES OF ENERGY The United States is a highly developed and industrialized society. We use a lot of energy - in our homes, in businesses, inindustry, and for traveling between all these different places. The industrial sector uses almost one-third of the total energy. The residential and commercial sectors combined use 39 percent of all energy. These two sectors include all 4 types of buildings, such as houses, offices, stores, restaurants, and places of worship. Energy used for transportation accounts for more than a quarter of all energy. Picture 2.1. Share of energy consumed by major selectors of the economy (2007) 2.1 Uses of energy in homes The ability to maintain desired temperatures is one of the most important accomplishments of modern technology. Our ovens, freezers, and homes can be kept at any temperature we choose, a luxury that wasn't possible 100 years ago
make acid rain less of a problem are: Only run the dishwasher and washing machine with a full load. Turn off the lights in empty rooms or when you will be away from home. Turn off the hot water tank when you will be gone for a long period of time. Don't use your air conditioner or heater as much. Install fluorescent light bulbs instead of incandescent light bulbs. Try to reduce, reuse, and recycle as often as you can. Try not to burn a fire often. When you are going to work, you could walk, ride your bike, or take a bus. Car-pool to a place with someone else. Try to use alternate fuels, like: ethanol, propane, or natural gas. Take the train or a bus for long trips. L imit the amount of long trips you take in your car. M ake sure that your vehicle's air conditioning system isn't leaking. Try not to overflow the gas tank. M ake sure that you are traveling at high speeds only when you need to.
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 react with water, oxygen and other chemicals to form more acidic pollutants, known as acid rain. Sulfur dioxide and nitrogen oxides dissolve very easily in water and can be carried very far by wind. As a result, the two compounds travel long distances where they become part of the rain, sleet, snow or fog. SO2 and NOx come mainly from power stations and factories burning fossil fuels, or from motor vehicles. · Carbon dioxide in the air can dissolve in rain water to form carbonic acid, H 2CO3
Environmental issues in Estonia The Earth is considered to be the most beatiful planets in the Universe. But our planet is threaten by environmental problems. Even a small country like Estonia can make difference. Our capital city is fighting against air pollution. But people produce much refuse and ways of recycling are getting old. Water pollution is also a problem in Estonia. We have factories that let their waste run into rivers. One of the biggest problems in Estonia is air pollution. Our air is polluted by exhaust fumes, because today we have a lot of cars, buses and other machines. In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the greenhouse effect. Tallinn wants to fight against it by offering public transportation for free, to Tallinn citizen. So that people wo
Report Compiler: Teisi Timma 8a Teacher: Esther Linask Tartu 2009 Acid Rain Acid rain is rain consisting of water droplets that are unusually acidic because of atmospheric pollution - most notably the excessive amounts of sulfur and nitrogen released by cars and industrial processes. Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. Acidic deposition occurs in two ways: wet and dry. Wet deposition is any form of precipitation that removes acids from the atmosphere and deposits them on the Earth's surface. Dry deposition polluting particles and gases stick to the ground via dust and smoke in the absence of precipitation. This form of deposition is dangerous however because precipitation can eventually wash pollutants into streams, lakes, and rivers.
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 its population has grown, the problem of water pollution has intensified. The simple fact that millions of people live along coastlines and near rivers means that these bodies of water are likely candidates for heavy and destructive pollution. It is hard to know now what our oceans will look like in the future
Water pollution Water pollution is the contamination of water bodies such as lakes, rivers, oceans, and groundwater caused by human activities, which can be harmful to organisms and plants and for all of us. First, we have to talk about the causes of water pollution. Domestic households, industrial and agricultural practices produce wastewater that can cause pollution of many lakes and rivers. Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment. Dumping of litter in the sea can also cause huge problems. Different items take different lengths of time to degrade in water. Oceans are polluted by oil on a daily basis from oil spills, everyday shipping and dumping. Secondly, it is very significant to know about dangers of water pollution.
Both uses are made possible because certain substances called nuclear fuels undergo fission when struck by free neutrons and in turn generate neutrons when they break apart. This makes possible a self-sustaining chain reaction that releases energy at a controlled rate in a nuclear reactor or at a very rapid uncontrolled rate in a nuclear weapon. The amount of free energy contained in nuclear fuel is millions of times the amount of free energy contained in a similar mass of chemical fuel such as gasoline, making nuclear fission a very tempting source of energy; however, the products of nuclear fission are radioactive and remain so for significant amounts of time, giving rise to a nuclear waste problem. Concerns over nuclear waste accumulation and over the destructive potential of nuclear weapons may counterbalance the desirable qualities of fission as an energy source, and give rise to ongoing political debate over nuclear power. What is radioactive decay?

Formaldehyde Formaldehyde is a colorless, flammable gas at room temperature. It has a pungent, distinct odor and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. Formaldehyde is also known as methanal, methylene oxide, oxymethylene, methylaldehyde, and oxomethane. Formaldehyde can react with many other chemicals, and it will break down into methanol (wood alcohol) and carbon monoxide at very high temperatures. Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin. A major source of formaldehyde that we breathe every day is found in smog in the lower atmosphere. Automobile
(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 people smoking despite its harmful effects. Because the smoker inhales only some of the smoke from a cigarette and not all of each puff is absorbed in the lungs, a smoker gets about 1 to 2 milligrams of the drug from each cigarette. A drop of pure nicotine would kill a person-in fact, nicotine can be used as a pesticide on crops. You might hear cigarettes referred to as smokes, cigs, or butts. Smokeless tobacco is often called chew, dip, spit tobacco, or snuff. How Many Teens Use It? More than 3 and one-half million teens between the ages of 12 and 17 use tobacco-that's about
(http://www.environmental-protection.org.uk) Technological Nowadays technology is evolving in an immense speed and that is why car manufacturers have to develop their products continuously to stay in the competition. Thanks to the technology development companies can increase volume of the production and also reduce the cost of product or improve car performance. Fuel consumption can be serious factor when people are buying a car. Because when fuel consumption is low then it will not harm consumers' financial status as much as cars with higher fuel consumption and also can be more neutral against environment. Mini Cooper with 1,6 litre diesel engine takes 3,9 litres of diesel for travelling 100 kilometres. The test was done by using both freeway and urban travelling route. That is even less than some of the hybrid cars. Mini has also equipped their vehicles with automatic start-stop system to keep the fuel consumption low
D i ox i n s a n d f u r a n s i n t h e atmosphere. Their impact on humans and nature. Emission sources What are dioxines and furans? The term Dioxin is commonly used to refer to a family of toxic chemicals that all share a similar chemical structure and a common mechanism of toxic action. Most dioxins and furans are not manmade or produced intentionally, but are created when other chemicals or products are made. This family includes: seven of the polychlorinated dibenzo dioxins (PCDDs), ten of the polychlorinated dibenzo furans (PCDFs) and twelve of the polychlorinated biphenyls (PCBs). · PCDD · 2,3,7,8TCDD · PCDF · PCB · PCDDs and PCDFs are not commercial chemical products but are trace level unintentional byproducts of most forms of combustion and several industrial chemical processes.

The impact of water pollution on wildlife and their natural habitat can be immense. While it may seem like preventing water pollution can be an overwhelming subject to tackle, there are also a number of things that the average person can do to help stop water pollution. Tips on Preventing Water Pollution The best solution for water pollution is prevention. While pollution that has already occurred is a current threat to all life on Earth, attempts to clean it up may cause even more harm.There are several steps that can be taken to help prevent water pollution from getting worse. Keep Machinery in Good Working Order The oil used to lubricate engines in all types of machines needs to be changed regularly. When the oil is changed, it presents a number of environmental hazards if not disposed of properly. As oil moves throughout the crank case of an engine, it breaks down into many different types of carcinogenic and even mutagenic compounds

Nurses work closely with doctors in the clinics, hospitals and medical centres. Nurses also provide many services to patients independent of the doctors. Various kinds of therapists give special treatment as ordered by the doctor. Other skilled workers serve clinics, medical laboratories, X-ray departments and operating theatres. Diseases There are many different diseases in the world. Some have been stamped out, others have improved and come back. New diseases have also developed, such as AIDS, stress, diabetes etc. These diseases are called the diseases of the 20th century. Today many diseases are well known and can be cured. Such diseases are flu, pneumonia, measles and many others. Coughs and cold are common diseases in winter. They can easily be cured if you rest and make medicine properly. But if you don't cure them well, they might turn into a worse disease. Cold, for example, can develop into sinusitis (põsekoopapõletik), cough into

A world government is both desirable and necessary. A world government is both desirable and necessary. What is there to gain from a world government? Are there any downsides to such world order? A lot of people believe that a world government is the only way in future. It would unite countries and people, eliminating differences. What would help to preserve peace in the world. Also a world government would help to rationalize recourses. As there would not be any duplicating, allowing much faster development of new technologies and faster production. In addition recourses would not pile up in one place because they would be diverted to places where the need is greatest.
Why have we got to create large institutional families? If people decide to have children, then they should value family life. Why should other people pay for the exhibition of junk which nobody wants? But you're already paying for the NHS through national insurance. Why should you have to insure yourself twice? Once the level of the benefit is higher than their take-home pay, why should they do a job? Why shouldn't those who cause air and noise pollution do something to reduce it? ... if mountainous countries like Japan can export good cars, why shouldn't they import their food?
Efficient initiatives to help protect the environment Just like our bodies, the environment functions best when it's in balance. Unfortunately, we're not quite there. Many of us believe that we lead lives that respect nature but our consumption habits give us away. Many little habits that seem to be sustainable are in fact polluting. Along with pollution, issues like depletion of resources, the rise of consumerism, and the "throw away" culture have led to serious issues. That being said, the fight's not over yet. Fortunately, more people than ever are both aware of and active in the protection of the environment. To protect the environment, waste management and recycling are crucial. When we recycle, used materials are converted into new products, reducing the need to consume natural resources. If used materials are not recycled, new products are made by extracting fresh, raw material from the Earth, through mining and forestry. Recycling helps conserve important raw materials an
A respirator can protect you against breathing in harmful contaminants that are in the air - if you use it properly. MIS ON RESPIRATOR? Respiraator on teatud tüüpi isikukaitsevahendeid (IKV). On kulunud üle nina ja suu. Mõned respiraatorid ka katta nägu ja silmad.Respiraator võib teid kaitsta vastu hingamise kahjulikke saasteaineid, mis on õhus - kui te kasutate seda õigesti. WHY IS IT IMPORTANT TO WEAR A RESPIRATOR? Workers doing cleanup or ripout jobs create a lot of dust that gets into the air. This dust is there even if you cannot see it. It may contain mold or chemicals like asbestos or lead. If you breathe in this dust, you might become temporarily or permanently ill. You might become ill right away or sometime in the future. Always wear a respirator for cleanup or ripout jobs. This can prevent harmful substances in the air from getting into your body and making you sick. MIKS on tähtis kulumise respiraator?
situations, when something is mentioned for the first time, some is used. We passed some beautiful houses on our way to the beach. There were some people at the station. There was some sand on the building site. In extraordinary situations or when we want to emphasize something no article is used. Poor people cannot afford to live in beautiful houses. There were people inside the house on fire! There was sand on my plate! The Indefinite Article is used when referring to an indefinite object (just any of the kind). Could you lend me a pen? (Any pen would do, I just need something to write with.) I'll take a sandwich. (Any of those on the plate.) 3 The Definite Article is used when the context specifies which particular one(s) is (are) meant. Could you turn off the light, please
regulate postal services. E.g. traffic signs are almost the same everywhere, why? Because of certain int conventions that require the states to have more or less unified traffic signs. States apply international regulations to national regulations and they have to be in accordance with each other, the states can always specify these regulations. Therefore, PIL regulates people indirectly. Another unique feature: domestic law sources have a clear pyramid (top to bottom: constitution, laws, individual contracts, they cannot contradict each other) and all sources are written. In PIL there is no such hierarchy, but there are primary sources (all are equally important) and secondary sources and all are not written. Primary sources: written documents (int treaties, conventions, declarations etc), international customary law (legally binding), fundamental principles (legally binding).
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius
on lessons, which gives them personal experiences, opinions and understanding that they will most likely to remember. Outdoor education creates meaningful learning experiences when teachers help children to move beyond simple observations to more complex activities that require higher-level thinking and collaboration with peers. Students nowadays do not spend as much time outside as the generation before them. This situation might cause them health problems and wrong lifestyle choices. Reasons why they are spending less and less time outside are that today we have so many indoor activities that students are keen on and parents are too cautious, preventing accidents. Outdoor education can improve student's health, while taking place in fresh air and making students physically active. The more students show their potential and skills, the more parents will allow them to be independent
