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 pollution can have serious consequences
Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and burning of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients. FIND OUT 5 WAYS HOW TO STOP POLLUTION. 2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth surface causing melting of polar ice caps, rise in sea levels and also flash floods, excessive snow or desertification. FIND OUT 5 WAYS HOW TO STOP GLOBAL WARMING. 3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food
Light bulbs are measured in watts. Air conditioners and hot water heaters are measured in BTUs, while energy used by cars is measured in gallons of fuel. They used a spreadsheet to figure out how much energy they consumed for each of their activities. Each of the lights, car miles, games, and other appliances was converted to a common unit of power consumption called kilowatt-hours. The spreadsheet was used to determine how many kilowatt-hours were used during each day, each week, and each year for each energy consumption activity. The spreadsheet converted their energy consumption to show them the amount of money it costs for each energy consumption activity. In the end, they were shocked to see how much money Jules' energy using habits cost compared 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.
Air pollution Janne Sinkarev, 8c Air pollution · Natural sources such as: Dust,smoke, volcanic eruption and · What is it? also forest fire. · Air pollution is the introduction of · Anthropogenic sources such as: chemicals, particulate matter, or aerosol sprays, toxic biological materials that cause gases,rocketry and some more for harm or discomfort to humans or millitary use. Also chemicals and other living organisms, or dust. Also transport: cars, motor damages the natural environment vehickles, marine vessels, planes. into the atmosphere. · Air pollution divided into two: Air pollution, which cames by human activity(Anthropogenic sources) and air pollution, which cames by nature(Natural sources)
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 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
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. Like heavy traffic in the morning, while you are
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.
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 would use more public transportation than their own car. Furthermore, it will change our climate. In addition our air is polluted by hydrogen sulfide from plants and factors (Especially in Kohtla- Järve and Maardu). Other big environment problem is garbage. Huge amount of waste is produced every day and it is all because of overconsumption
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?
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 solve them. Firstly, the main issue is pollution, that is caused by our own carelessness and thoughlessness. In Estonia there are too many old cars and other vehicles, which exhaust fumes that pollute air what we breathe. Although, there are some newer vehicles like busses and cars that contaminate less and even few electric cars, people do not pay enough attention to it. When the levels of pollution are too high, it may cause some serious diseases. The second aspect is that people fell quite a lot of trees, but that is not so big problem. In Estonia there are a lot of forests and groves. Also, people are planting new trees all the time and know abot the importance of green. Lastly, one of the issues is that people consume too much and therefore produce a lot of garbage. Most of the people recycle things like plastic, bottles and paper, but some do not know or care what kind of damage growing landfills

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.
Internal marketing evironment is divided into 6 different groups; which are customers, competitors, suppliers, distributors, employees and stakeholders. Also this assignment is provided with the SWOT analysis, where strengths, weaknesses, opportunities and threats are examined. Mini Mini was at first manufactured by the Austin Motor Company Ltd. In 1957 Alec Issigonis was commissioned to develop a new type of small car. At the same year were the first sketches of Mini made and after that the Mini model is been created from wood and also the most important mechanical parts for Mini has been developed. Four years later the Mini hits the streets. In 1965 the first Mini with an automatic transmission enters the market and in 1969 Mini gets itself an own badge. In 1971 Mini was the best-selling British car in the world. 1994 BMW group bought the Mini and year after that Mini was voted as the best car of the century

Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year.
Cars should be banned in city centers Nowadays, most of the people have their own car. Most of them say that they can´t live without it.Many environmentalists opinion is that cars should be banned in city centers. I support this view for a variety of reasons. First and the most important thing is the pollution. Using cars increase the level of pollution in big city centers. This is especially important because town centers always consist of tall buildings and narrow streets which often hold the pollution in one spot.Global warming is big problem all around the world. So, people should use public transport instead of their own car, if they do think about the nature and the air they breathe every second. Secondly, with less traffic there would be fewer accidents. Nowadays many people, especially younger persons, die in the car accidents every week. When we reduce the number of cars in city centers we can avoid these kind of disastrous.
Also we have, for example, deforestation problem and traffic jams, for instance, in Tallinn in rush-hour. Nevertheless, those problems are not so significant than previous. One of the biggest problems in Estonia is air and water pollution. One example of air pollution is exhaust fumes. Today we have a lot of transport: cars and buses, in the main in our capital. Gases which are produced by cars contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the green house effect. Furthermore, it will change our climate. In addition our air is polluted by hydrogen sulfide (H2S) from plants and factors. Substantially, in Kohtla-Järve and Maardu. Our water is also polluted. We can't drink it, because there are a lot of chemical ingredients. In some cities water is chlorine a lot. As I know a lot of waste waters are putting out to see, near in the beach. In witness of it is appearance of blue seaweeds. In my opinion these thing is very
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
How can we reduce air pollution levels in our cities? Are our cities clean and fresh enough? Unfortunately people don't see that actually cities aren't clean enough. The Aair pollution is growing every day, but how can WE change it? Firstly, we should watch out for the garbage we produce. Many things that are thrown away can be recycled, but some of the people aren't aware of that. They throw things away which may be dangerous for nature. Another solution is to use more buses and bicycles. Every family member doesn't need his/her own car. When you move more in fresh air, you will feel better yourself, your health will be better and you will reduce air pollution levels. Finally, big-factory owners should pay attention where they build on their factories. I think that it is very important that they don't build them in the middle of cities. The pollution twhat comes from the factories is bigdrastic. In conclusion, there are many ways to make our cities' air pollution levels lo
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
What is a electric car An electric car is a plug-in battery powered automobile which is propelled by electric motor. Electric cars are a variety of electric vehicle (EV); the term "electric vehicle" refers to any vehicle that uses electric motors for propulsion, while "electric car" generally refers to road-going automobiles powered by electricity. While an electric car's power source is not explicitly an on-board battery, electric cars with motors powered by other energy sources are generally referred to by a different name: an electric car powered by sunlight is a solar car, and an electric car powered by a gasoline generator is a form of hybrid car. Thus, an electric car that derives its power from an on-board battery pack is a form of battery electric vehicle (BEV). Most often, the term "electric car" is used to refer to pure battery electric vehicles. What types electric cars we have Usual electric cars have a batterey and elecrtic motor jusr like toy cars.
such as water, air and forests products. However, things have improved in recent years. What has been done to improve the environment in Estonia? People today are too lazy to think or to do something to protect the environment. They dump their waste into forests and even rivers which causes air and water pollution. Fortunately, people have come up with different organisations and events to help clean our envrionment. An annual event such as ,,Teeme ära!" motivates people to go out, spend time with friends and family and have fun while cleaning up the trash. This event first took place in 2008 and is now one of the biggest worldwide environmental events. Estonian Commission on Sustainable Development is one of the organisations that is working on improving the conditions of our country´s environment. This organisation focuses on the growth of welfare, economical balance and viability of the Estonian cultural space. Its
Topic Health Introduction Good health is very important for us. We should do everything we can to stay healthy. Being in good health means having our body and mind in good working order, free from disease and pain. Ways of keeping health There are many ways for keeping health. To stay healthy we should eat right foot, dress comfortably, spend much time in fresh air, have enough rest, keep ourselves clean and have regular checkups with the doctor and the dentist. A big part of prevention of diseseases is sporting. Poeple need to have phsical exercise. If they can not have it, they will get stressed and they will be infected with dieseases much easier

The Major Environmental Problems in Estonia I would like to talk about the major environmental problems in Estonia. There are many of them but I would like to point out the most important of them: air pollution, huge amounts of waste because of overconsumption and abuse of the natural resources. To begin with, air pollution is a big problem in big cities and in industrial areas. Air pollution is often caused by the exhaust fumes of the cars or by big factories. It affects nature and peoples health causing them breathing problems. Secondly, huge amounts of waste are being produced every day and it is all because of overconsumption. Although, in recent years peoples knowledge about recycling and using eco-friendly products have improved, there are more landfills in Estonia than ever before. The government should take some actions and instead of talking about recession, improve recycling programs. Last but not least, abuse of the natural resources is also a
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.
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 McDonald`s and Burger King are not using plasti
Summary The present summary is based on the book "Northern Europe’s seas. Norther Europe’s environment" by Britt Aniansson. Oceans and seas are polluted every day by different substances that reach the waters from different sources on land and at the sea. The author points out four main problems in the marine environment. One of the main problems is the chemical pollution which is caused by natural or man- made halogenated compounds, pesticides, dioxins, chlorinated organic materieals and so on. These compounds are causing deformage in marine animals and are storaged in their fatty tissues. They have also been found in organisms throughout the world oceans because they are dispersed quickly by winds and currents.
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
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.
This is a big problem because our exhaustible resources are running out. This is a problem that has huge consequences. It means that in the future people may not have enough resources, beacuse right now we are using too much. Secondly, there is a huge amout of waste and pollution. Clean air is our most valuable resource, but it is getting more and more polluted, in the same way as the water. For example, the pollution of water kills hundreds of thousands of birds and water animals. As a result of pollution , there are holes in the ozone layer, which in its turn loses some of its protection. Pollution is also the cause of acid rain, which damages the forests. In conclusion, we cannotonly consider with our needs, we have to think more broadly. In the future our children will need the same resources in the same way as we do. If we do not consider with the others' needs, and increase the overconsumption even more, then we will finally destroy our planet.
has thought that people could use environmentally friendly fuel for cars and use natural heating materials. The other major environment problem is water pollution. Many peoplerefer their carbage pipes andchemicals substances to bigger watercourses, which unfortunately damage and destroy many spices who live there. According to Poku, people shouldn't was their car, clothes or themselves in water.However they should ban toxic substances flow to water by manufactorys.As a result, we can save many aquatics and other animals, who use lake or river water for drink. We all know that currently very active business"recycling" has been save pollution of the trash what doesn't decomposist or need many years for that. If people continue with this same active then wild animals are rescued.
