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 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
Fourth level Fifth level Negative aspects of solar energy Solar energy does not work at night without a storage device such as a battery. Cloudy weather can make the technology unreliable during the day. Solar technologies are very expensive. Requires a lot of land area to collect the sun's energy. Wind energy Most wind energy comes from wind turbines. Wind turbines are used to wring electricity from the breeze. Wind turbine use has increased at more than 25 percent a year. Wind is a clean source of renewable energy that produces no air or water pollution. Wind is free, operational costs are nearly zero once a turbine is erected. Negative aspects of wind energy Wind turbines make noise. Slowly rotating blades can kill birds and bats. Wind is variable: if it's not blowing , there's no electricity generated. Wind turbines are expensive. Hydroelectric power
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
INKA ISESEISEV TÖÖ Me and the environment It is very important to keep the environment clean. Many people don' t think what wrong behavior does with the envoronment. Very much people throw their garbage into th environment. Why people throw so many things into the environment whent there is so much garbage bins everywhere, many collecting points. I don' t throw my garbage to outside, i put it in the garbage bin. I will try to sort my garbage. But there's also things why I am forced to ruin nature . I really don 't wanna do that but I can't change it anyhow. I'm forced to do it because in that department whe I live , here is no drainpipe. Because of that we have to throw all our used water to the nature. Everything what we do, what needs to waste water, that's goes all to the nature
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 and protects natural habitats for the future. As recycling saves energy it also reduces greenhouse gas emissions, which helps to tackle climate change
How to save fresh water? We all know what the problem is. Our lakes are dirty, people are wasting water for no reason not understanding how important it is not to waste it because we may soon run out of fresh water. It can seem like there's no solution, but there is! A few simple changes can help a lot. First of all, it is really important to keep our lakes clean, because nature is the premier source of fresh water. So people should stop dropping garbage into the lakes or near them. And walking pets near the lakes is also not such a good idea. It's not very nice to find some animal's body wastes while going to swim. Secondly, think about how much water you use. A few simple steps could save your money and help protect the environment. For example you should prefer shower to bath or you should turn the water off while brushing your teeth.
Foundation, the long list of health- and environment- improving benefits of having trees around include reducing your air-conditioning costs by providing shade; possibly raising the property value and resale appeal of your home; pulling carbon dioxide out of the environment and creating oxygen; improved water quality; and providing you with calming surroundings. .

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,

of these can vary considerably. Some technologies are already mature and economically competitive (e.g. geothermal and hydropower), others need additional development to become competitive without subsidies. This can be helped by improvements to sub-components, such as electric generators. The table shows an overview of costs of various renewable energy technologies. For comparison with the prices in the table, electricity production from a conventional coal-fired plant costs about 4¢/kWh. Though in some G8 nations the cost can be significantly higher at 7.88p (~15¢/kWh).Achieving further cost reductions as indicated in the table below requires further technology development, market deployment, an increase in production capacities to mass production levels,and of the establishment of an emissions trading scheme and/or carbon tax which
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. 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
that are in no danger of a lack of long-term availability. Some natural renewable resources such as geothermal power, fresh water, timber, and biomass must be carefully managed to avoid exceeding the worlds capability to displace them. Solar energy is the energy derived directly from the Sun. Along with nuclear energy, it is the most important source of energy on Earth. People usually use solar energy to produce electricity and heat. Wind power is the conversion of wind energy into a useful form of energy, such as electricity, using wind turbines. These wind turbines are popular in counties, where the average speed of the wind is at least 6 meters per second for example in Germany, Denmark, USA and India. Hydropower is energy derived from the movement of water in rivers and oceans,it can be used to generate electricity using turbines, or can be used mechanically to do useful work.

Introduction To be honest I got the list of topics after most interesting ones for me were taken. At first I was not very satisfied with my topic but then I realized that this could be actually really interesting thing to make a report of. I chose this particular topic because I have always been interested in green energy. This topic gave me an excellent opportunity to improve my knowledge about these kinds of things. For me this report is a great challenge because I have not done anything like this before, especially in English. Primary goal for me is to improve my knowledge about renewable energy and also usage of English language. This report is going to talk about biogas. It provides a brief review of usage and future prospects of the biogas. I have tried to make this report as understandable as
and if one of the species goesis going to extinct, then the whole natural ecosystem will be disheveled. It will affect humans as well because we are a part of wildlife. Animals and plants benefit us just by being there. These benefits, whichthat are called "ecosystem services", which most of us take for granted. Some of these services are obvious; fFor instance, there are the plants and animals that we eat. Meanwhile, photosynthetic plankton in the sea and green plants, provide us with the oxygen we breathe. If those things disappear humans will lose physical goods in their life. From a lot of different animal species that are in a danger of extinction we, humans, get the medicine that cures will cure our sicknesses. The use of animal parts in traditional medicine can also contribute to a species' decline, despite there being no real evidence of the efficacy of these treatments. The

The government should close The these companies who have polluted rivers first thing for a long time. This way our rivers will The we can do is be cleaner. People would have clean water living to stop to drink and to swim in. conditions in throwing There is also a way to fight against our city are litter. Also, air pollution. It is mostly caused by getting worse the city factories, so we should force factories to and worse. should place put filters on their chimneys. We can also Exhaust fumes

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 to the health of humans and animals. Water pollution may not damage our health immediately but can be harmful after long term exposure. Such as the water pollution is global ecological problem we have to know
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 big problem in Estonia. Big fatories
Water pollution Secondly, water pollution is also a main issue. Many peole throw rubbish in rivers and lakes. Ships at the sea cause oil problems, where oil flows in the water and causes a lot of damage, like killing the sea animals and also birds, who are on the seacoast, where the oil reaches. When these problems continue, soon we won't be able to swim in a clean body of water and the drinking water becomes unusable. In some places there are floods after the snow melts or in autumn, when raining cause sea level rising. When water retreats, it brings along trash and rubbish from the streets in the sea or rivers. Many peole have built ramparts, to avoid the consequence of floods and also picked up rubbish from coasts, where seawaves have washed the trash.
diagnosed with cancer - the most common cause of death after heart disease. Most widespread are cancers of the lungs, breast and colon. Diseases such as bronchitis, lung cancer and heart diseases may all eventually appear in people exposed to air pollution. When the wind blows, then it carries the pollution with him. Futhermore, the rain reduces the pollution. Air pollutants such as ozone, nitrogen oxides, and sulphur dioxide also have harmful effects on natural ecosystem. A clean air supply is essential to our own health and that of the environment. But since the industrial revolution, the quality of the air we breathe has deteriorated considerably - mainly as a result of human activities. The pollutant emissions from road vehicles are regulated separately for light-duty vehicles (cars and light vans) and for heavy-duty vehicles (trucks and buses). It is located in the atmosphere, air pollution is able to travel easily
composition of the air? They only used the knowledge of moving the air. Turning to water which covers over 71 % of Earth´s surface. It is also in underground and, naturally, in the air. Even clouds consist of water steam. People, animals and plants couldn´t live without water. Their bodys contain more than a half of water, they need water constantly. Thirdly soil, which is the surface of all continents. The soil on the Earth is not the same fertility. Some places are covered by different plants and some are not, imagine a desert, where isn't growing anything. I'm sure you know there are many ecological problems today. It is the pollution of seas and oceans, dissapearance of many species of animals and plants, acid rains, destruction of the ozone layer and etc. In spite of this, people are still harming the enviroment. The great number of cars contribute much to the air pollution. Many factories are built near rivers into which they put their chemical waste
diabolical individuals who set out to invade Africa and take our people as slaves. They braved the inhospitable environment and maneuvered our forebears into handing our brothers and sisters to them. A capitalist Nigger must develop the same killer instinct and death-wish as the Caucasian. He must develop this killer instinct as if he is to succeed in laying this assault on the corporate world. He must develop the same whatever-it-takes attitude of the Caucasian. He must keep his eyes on the prize – that is using the same means available to our brother-Caucasians to achieve his goal of levelling the playing field for generations of Blacks to come. A capitalist Nigger must not have anger which can disrupt his concentration. He must cultivate the friendship of the Caucasian, let him mentor him. Listen, right now, we must accept the fact that he is far too ahead of us for us to continue to sit on our high hides and allow him to move even further ahead
Some people say that every body should do voluntary work for environment Nowadays when most of the people live in city environment don't see what that makes to the nature. Big city's wastes lot of water and product a lot garbage all so waste air with fumes. It would be great when people who take something from the environment give something back to it. This is easy when just start doing something. If nobody doesn't drop junk on the ground then that's a good thing to. Also should take part on different trees planting and junk cleaning events. I guess that government and local authorities should make more and more with that kind of purpose events.
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 its population has grown, the problem of water pollution has intensified
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 recycling banks than the benefits gained from recycling materials. It could be argued that there is more energy used up

....................13 Introduction What is nuclear power? Nuclear power is any nuclear technology designed to extract usable energy from atomic nuclei via controlled nuclear reactions. The most common method today is through nuclear fission, though other methods include nuclear fusion and radioactive decay. All utility-scale reactors heat water to produce steam, which is then converted into mechanical work for the purpose of generating electricity or propulsion. In 2007, 14% of the world's electricity came from nuclear power. More than 150 nuclear-powered naval vessels have been built, and a few radioisotope rockets have been produced. Nuclear life cycle The Nuclear Fuel Cycle begins when uranium is mined, enriched, and manufactured into nuclear fuel, which is delivered to a nuclear power plant. After usage in the power plant, the spent fuel is delivered to a reprocessing plant or to a final repository for geological disposition. In
That comes from cars. It makes me feel very ill. Then I just have to step on trash, because people can't wait and look for a bin. That's why our streets are so dirty. Everywhere I go, there are always some workmen building big houses. If we improved public transport or made electric cars, our streets wouldn't be so polluted. In Tallinn, for example, the air there is so polluted, that you can hardly breathe there. If the authorities put bins everywhere in the streets, our cities would be cleaner. The second thing is, that people still drop litter on the ground, even if there is a bin somewhere nearby. If we didn't build so much houses all around cities, we could save money from that and better build animal parks, green areas and playgrounds for children. If there were more green areas, people would have more oxygen. All in all, we must understand the importance of oxygen and where must litter go,
· Energy, food and water sources, transportation systems and basic infrastructure, must all adapt to emerging pressures from climate change, dwindling resources and growing urban populations. · 70 million people a year migrate from the country to cities. That is about 130 a minute, that means very massive globalization. · At this rate, our future cities may turn out to be quasi-temporary, missing the basics of human life, such as water and electricity, still belching out the waste of fuels that warm the globe. · The New City in China: The buildings and all around it work like biological, growing beings, photosynthesising and producing and re- using their own energy. China will be largest solar manufacturer in the world. · Masdar city in United Arab Emirates near Abu Dhabi. First city in the world, that would rely on the renewable energy sources. 6 square kilometers, home for 50,000 people and 1,500 businesses.
Simple and small ways affect the enviroment for the better Everyone can do something for the enviroment. All of us should do something, because enviroment is very important to people. Our planet is changing and we need to help it change for the better. One way how to help the enviroment is saving energy. You should switch off anything, that uses electricity. If you’re not using it, then turn it off, it’s simple. This goes for lights, televisions and so on. Also try unplugging if possible, because even when an appliance is turned off, it still may use power. You could switch your light bulbs to LED light bulbs, because these are using less energy and even last longer. If you use renewable energy sources, you won’t cause burning fossil fuels, that causes pollution. Another way how to help the enviroment would be saving water
