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. Virtually all types of water pollution are harmful ...

Water pollution and society This essay is about fresh water and pollution. It's based on an article by David Krantz and Brad Kifferstein. I read it through and now I'm trying to give the conclusion of the article as well as express my own opinion. 70 percent of planet Earth's surface contain water. Water is the beginning of life and vital natural resource. It's vital for every living organism. That's why we have to keep the water bodies clean and stop polluting our fresh water. It's hard to believe, but planet Earth is in great danger. People can't see the whole picture. They are being indifferent to the future. Everyone thinks about themselves and tries to find a better and easier way to get rid of garbage and waste. Money is everything for them. Money talks and nobody cares about giving a dollar to save the nature. Usually a person thinks that what difference can he make. But if everybody think so, it's o...
How to Stop Water Pollution Water pollution is one of the biggest threats to the environment today. There are several sources of water pollution ranging from sewage and fertilizers to soil erosion. 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 change...
WATER POLLUTION THERE ARE THREE DIFFERENT WAYS THAT WATER CAN BE POLLUTED. ⦿ Surface Water Pollution - Most common type, you can visually see the pollution floating (plastic containers or oil and gasoline spills). ⦿ Ground Water Pollution – This becomes more relevant as it affects our drinking water. It become infected by toxic chemicals. ⦿ Microbial Pollution – Found in the countries who don’t have the facilities to cure the water so the bacteria and viruses grow in the water. The people have no other way of getting water so they are forced to drink it. WHAT CAUSES WATER POLLUTION? ⦿ Wastewater ⦿ Marine dumping ⦿ Industrian waste ⦿ Radioactive waste ⦿ Oli pollution ⦿ Underground storage ⦿ Global warming WHY IS IT A PROBLEM? ⦿ It causes worldwide disasters and deaths. ⦿ It may not damage our health immediately but can be harmful after long time. ⦿ Industrial waste often contains...
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...
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 transportati...
Good afternoon, i talk about environmental problems in Estonia. plakatile ei kirjuta :D Main environmental problems in estonia: · Oil shale mining and burning · Excessive tree felling · Air pollution · Eutrophication Oil shale mining and burning. Estonia environmental problems are mostly caused by oil shale mining and burning. About 30 000 Hectare ground is unusable. We have a large ash mountains thanks to burning of oil shale. To reduce pollution we need to decrease mining of oil shale and shale-based electricity producing. Air pollution the biggest air pollution is in large cities. It´s caused by big factories, a lot cars and deficient environment ordinance. To decrease air pollution we need to use less cars and more public transport. Eutrophication It means water enrichment of nutrient. In eutrophic water there is less oxygen and water quality low. There are some things to improve it: · To disable phosphate use ...
Report Poku Organisation Poku deals the most common environment problems. For example air pollution, water and contamination of ground. Poku has taken charge of all kind package recycling problems. The most common environment problem is air pollution. It is caused by the most common but almost unavoidable activites(heating stoves,car driving, emissions from manufacturing plants). Those activities are hard to avoid however Poku 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 res...

We do not inherit the earth from our ancestors, we borrow it from our children Our planet has resources which are necessary for people's everyday life. As the population is growing the resources are decreasing. One of the things that affects the life on the earth is overconsumption. We consume more than what the earth can regenerate. 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 als...
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. If this method will be chosen, city needs to build special cycling roads. Thanks to these roads traffic should be safer. More energy is used up taking items to re...
I'd like to present the main issues of our planet and today i'll name 5 of them. These are air pollution, water pollution, endangered animals, deforestation and rubbish. Air pollution Firstly, lets talk about air pollution, which endangeres our life in cities and also the forests near by. Cars and factories blow poisoned gas in the air and it mixes with the oxygen, so the 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 ...

Presentation about enviroment Good afternoon everyone. First, let me introduce myself. My name is Valter and I am a student of Tallinn University of Technology. I'd like to talk about environment, its pollution and protecting. I shall only take 3 minutes of your time. Let me begin with the word enviroment and what it means! It means surroundings in which people, animals and plants exist. These are the things that we need, to be alive, but they are also many man-made things and technical progresses that harm the nature. Therefore we can´t live on this planet without basic components which are needed for human existence - air, water and soil. Firstly air, which is mostly a mixture of oxygen and nitrogen. People, animals and plants can ´t live without air. Without oxygen there would be no fire. So we can see, that air is the basic condition for life on the Earth. Did you know that till 18th century people...
The most pressing environmental issues in Estonia The earth is considered as one of the most beautiful planets in the Universe. Unfortunately, our planet is suffering due to many problems which should be solved before it is too late. Of course our country is not an exception. The major problems that are facing our country today are air and water pollution and recycle problem. 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 ...

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. 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 ...
Sustainable city planning Sandra Erik 11L What is sustainable city planning? • A sustainable city, or also know as eco-city, is a city designed with consideration of environmental impact, inhabited by people dedicated to minimization of required inputs of energy, water and food, and waste output of heat, air pollution - CO2, methane, and water pollution. • It should meet the needs A sustainable city should be able to... • feed itself with minimal reliance on the surrounding countryside, and power itself with renewable sources of energy. • create the smallest possible ecological footprint • produce the lowest quantity of pollution possible • efficiently use land • compost used materials - Practical Achievement • Different agricultural systems - agricultural plots within the city – reduces distance. • Renewable energy sources - wind turbines, solar panels,...
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...

Turismi negatiivne mõju majandusele ja keskkonnale MAJANDUS 1. Riikide poliitiline ja majanduslik olukord mõjutavad oluliselt turismi. Riikides, kus on näiteks orkaanid, maavärinad, terroriak või haiguste levik, võib turistide arv olla väike. 2. Turismi abil loodud töökohad on tihti madala palgaga ja hooajalised. Turism võib ka kergitada toodete, teenuste ja kinnisvara hinda kohalike jaoks. 3. Suur osa turismitulust viiakse sihtriigist välja. Selle põhjuseid on mitu: välismaise päritoluga majutusasutused ja reisiagentuurid, reklaamikulud ja toorainete hankimine turistide jaoks. KESKKOND 1.

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. Another problem that affects the marine life is excess phosphorus and nitrogen flow into the sea from towns, factories and other man-made sources which cause intense alg...

Miina Härma Gymnasium Acid Rain 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 strea...
Environment in Estonia Nowadays environmental problems are too big to be managed by individual persons or individual countries. In other words, it is an international problem. But what are the biggest problems in Estonia,why and how people could solve it? Air, water, and land pollution rank among Estonia's most significant environmental challenges. The combination of 300,000 tons of dust from the burning of oil shale by power plants in the northeast part of the country and airborne pollutants from industrial centers in Poland and Germany poses a significant hazard to Estonia's air quality. Estonia's water resources have been affected by agricultural and industrial pollutants, including petroleum products, which have also contaminated the nation's soil. Some rivers and lakes within the country have been found to contain toxic sediments in excess of 10 times the accepted level for safety...
Acid rains Stefani Nimtsuk What is acid rain? Rain or any other form of precipitation that is unusually acidic It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids History Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon The term "acid rain" was generated in 1972 Canadian Harold Harvey was among the first to research a "dead" lake Public awareness of acid rain in the U.S in...

How to deal with water shortage problems? Water covers more than 70% of the Earth's surface and it is the most valuable resource in the world. We need water to live on this planet otherwise life on Earth wouldn't be possible. Many countries suffer from water shortages. There is no fresh water for people usage. It's actually a major problem in the world but what can we do to decrease this? Firstly, people need to realise that there are many other people in the world who does not have accessibility to water. We can decrease it by not wasting water on pointless things for example long showers and watering flowers outside the house. By doing this we will economize water and it may be possible for other people to use fresh water as well. Secondly, it is really important to keep the water fresh and clean but many factories let their sewage into the groundwater which can cause a pollution and the lack of fresh water a...
Acid rain is rain or any other form of precipitation that is unusually acidic. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of compounds of ammonium, carbon, nitrogen, and sulfur which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the production of sulfuric oxides into the Earth's atmosphere with positive results Since the Industrial Revolution, emissions of sulfur dioxide and nitrogen oxides to the atmosphere have increased.[2][3] In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England.[4] Though acidic rain was discovered in 1852, it was not until the late 1960s that scientists began widely observing and studying the phenomenon.

The results of the opinion poll are presented below. Pollution General situation at Poku is satisfactory as the level of water and noise pollution is rather low as there are no big industrial enterprises in the vicinity. Problematic areas are air and litter pollution as many tourists visit the place leaving behind exhaust gases and rubbish on the ground. Wildlife In the forests near Poku there is comparatively rich in wildlife. The only problem seems to be cutting trees which may leave the local animals without their usual habitat. Recycling Recycling of paper and glass is very well organised in the area of Poku. More problema...

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 no...
Recreational use of Pärnu river The catchment area of Pärnu river is 6920 km2 (For example Emajõe river drainage area is 9740 km2). The output is 70m3/s, mean altitude above the sea level - 50 m, maximum altitude - 78 m, mean flow 64,4 m3/s and precipitation 700 mm. Main problems are floods, agricultural pollution, pollution from the local communities, drainage system and flood plain grasslands. There is an excessive flooding in spring. The most known is the Soomaa swamplands flooding in april. It is called to be the fifth season. A lot of rich soil are situated near the pärnu river, for example some of the biggest farmlands are situated in the Järva county. 83% of phosphorus and 79% of nitrogen originates from human activities of the total discharge of biogenes from Pärnu River basin. The soil does not bind a huge amount of the nutrients. 65 % of the treatment plants are over 15 years of age and most of them are programmed in ...
Water creates energy Eduard Kamenski 11a form The world uses energy from many different sources, such as: hydroelectric power, nuclear power plants, solar energy, and wind generated power. There are positive and negative aspects of each source, but which source of energy is best? My opinion is that the best source of energy is water and I'll bring up some facts why do I think so. Hydroelectric power is currently the world's largest renewable source of electricity. It accounts for six percent of the worldwide energy supply or about fifteen percent of the world's electricity. Water has been found to be a major source of energy. Water power is utilized at present mainly as hydro-electricity. It is produced from moving water and from falls with the help of turbines and dynamos. Hydro-electricity has acquired great significance as a source of energy in the country in the present times and is being put to different uses. The following are the...
Environmental Issues and Sustainable Development in Estonia We are all a part of the environment that surrounds us. Unfortunately, people do not always know how to take care of the things that are vital to our survivor but what we take for granted 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.

Environmental problems Many environment problems are caused by human actions. 1. Air pollution. Use public transportation instead of your own when going to work. Air pollution is also drastically reduced by conserving energy. It is the little things, like switching off fans and lights when you are not at home. Electricity causes the burning of large amounts of fossil fuels, which in turn pollute the air. Solar power is a fantastic solution.
