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.
The RRR rule Reduce- reduce your waste. That means, use alternatives to things that you would just throw away. For example: instead of paper cups and plates use ordinary plates. Reuse- Use thing that you have already got or give them to people who need those things. For example: glothes, use newspaper as a wrapping paper. Recycle- recycle thing. It does not take too long and it makes so much differencs Saving energy and your money Save electricity - people use a lot of electricity only because they forget or leave electrical appliances on. How: unplug everything that you do not use and do not forget to turn the light off Save water - Wasting water wastes electricity wich wastes energy. How: repair all leaky water mechanisms and if possible take shorter showers Saving energy and your money Save gasoline- It takes a lot of energy to operate a car. How: use other healthier alternatives like bicyclel or

efficient than cars, and they help reduce wasteful traffic congestion. If we increase their use, the governments will increase the frequency and convenience of the schedules, which in turn will further increase their use, thereby discouraging individual car and truck traffic. 5. Plan Ahead --- Reduce your driving by planning ahead and combining several small trips into one, whenever possible. Over a year's time, your savings in energy, money and time could be substantial, while your part in traffic congestion shrinks. 6. Live Near Your Place of Work or School --- If it takes more than 30 minutes to walk to your workplace or school, perhaps you could move closer. 7. Demand Higher Fuel Efficiency Standards --- The gas-guzzling of most cars and trucks is an embarrassment for our country. We're being thoughtless about our children's needs and future. Each of us needs to demand that our elected officials set much higher fuel- efficiency standards. 8

................................................................................ 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 possible. By the end of this report I want to come to a conclusion whether biogas is

Money in our everyday life Money plays a quite important role in our everyday life First of all, nowadays mostly everything circles around money and how much people can afford things. Secondly, every adult has to work so they could get the paycheck at the end of the month they need to pay the bills, buy food and to pay for any other expences. On the other hand, money is not the only thing in the world and money does not give you everything. You can't buy a family and friends. In conclusion, even if people work every day in order to pay for their expences, money is not the only thing in the world that makes people happy and satisfied with their life Advertising on TV Advertising on TV is a very popular way that companies use to advertise their products. First of all, advertisements on TV are called commercials and to get air time on Tv is very expencive and not every company can offord it.

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. Now that solar radiation is at a climactic peak, we can reap power from the sun using solar panel systems. These range from home systems to larger scale systems powering entire communities and cities. 2. Deforestation.
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 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

Each part has a special job, and all the parts work together to keep you alive and healthy. Good health is one of the most important things in life. There are certain things we can do to stay healthy. We should eat a balanced diet that includes the right kinds of food and drink plenty of clean, fresh water. We should exercise regularly, strengthening our muscles and keeping us in shape. Exercise helps the blood circulate around our bodies, cleaning out waste and supplying plenty of oxygen. It is also important what we get enough sleep. The number of hours we sleep we need depend on our age. Young babies sleep
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.
requires little energy for space heating or cooling. Sounds appealing right? Sustaining the earth for our future generations and also in the long run benefit from living there with paying lower taxes. However sadly, nowadays there is known to be only up to 20,000 passive houses world-wide out of 1,6 billion households. Which leaves us only 1 house out of 80,000. So why such shocking figures? The main reason, why there aren´t enough energy efficient homes, is because it costs more money to build one of those. Another reason is, that many houses were built before the energy laws were passed. So let´s talk about the cost. It is said that passive homes cost 6 to 12% more than other new homes, supposedly a medium house costs about 100,000 euros, so you would have to pay 12,000 euros more, it ´s actually quite a lot, isn´it? And to ensure that your passive house is efficient, it would be wise to get the certification, which ensures
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. I see this as a more sufficient way compared to saving electricity for example (but which, of course, is important too), for it’s generally easier to just recycle. It's really easy to carelessly waste energy–– leaving a light bulb on here and there, keeping the air conditioning on at home when you're out at work or school all day etc. Although it may not be obvious, there is a connection between energy use and the environment. As the same with recycling; when you consume less power, you reduce the amount of toxic fumes
persecuted for protesting against Shell and the Nigerian dictatorship over exploitation in their homeland. The Body Shop At HomeTM, the direct-selling arm, was launched in the UK in 1994, Canada in 1995, Australia in 1997, and USA in 2001. It has now rolled out in 48 states in the USA and is set to grow even bigger. The Body Shop continues to increase its environmental practices. In 2001, The Body Shop UK region and service centre head offices in Watersmead switched to Ecotricity providing them with energy from renewable sources. In addition, a number of The Body Shop® stores have now converted to green electricity while the rest of the stores are set to follow suit. Campaign successes include the Against Animal Testing campaign. The campaign led to a UK-wide ban on animal testing on cosmetic products and ingredients in November 1998 and led to the largest ever petition (four million signatures) being delivered to the European Commission in 1996.

Acid rains This morning you contributed to atmosphere desolation H ow it is formed? Acid rain is formed by burning fossil fuels such as coal, natural gas, and oil. Gases of acid rain Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. Our health and acid rain Acid rain effects even our health. Breathing and lung problems in people (especially those with asthma) and have been linked to acid air pollution. Some things that you can do to 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.
celebrating Africa’s coming of age, as more and more African countries received their independence either from Britain or France. It was especially a poignant time for Africa, as then British Prime Minister Harold McMillan articulated his now famous “winds of change” sweeping Africa. We had high hopes for Africa, for the Black race, that the insidious imposition of foreign rule on us, the looting of Africa’s natural resources by our colonial masters accorded us would be things of history. That is more than forty years ago. Unfortunately, the promise of independence has not been fulfilled. Today, Africa has become more desolate; there is more starvation, diseases and non-provision of essential services than when we got our independence. There are all kinds of wars in Africa than the rest of world put together. The majority of so-called Africans leaders want to stay in power until the day their bodies are put in the grave

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 CO2 + H2O H2CO3 · During the last century the rain water in some parts of the world has become far more acidic. This acid rain has been caused by the

............................12 References..........................................................................................................................................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.

One of the biggest energy-wasting manifestations is the compulsion to begrudge energy. 33. One need not have a better theory to object to a theory's defects. 34. One needs more energy, higher frequencies, more bandwidth, and less interference in order to sustain a finer quality of attention. 35. One who has authority over others is responsible for deterring them from behaving unustly toward one another and for effecting the redress of injustices when they occur. 36. One who is not still looking for answers is either a buddha or a damn fool. 37. People say that they want to be "loved for themselves" but I find that insulting. I want to do things that are worthwhile and be admired because my actions are admirable, not for foolish subjective reasons. 1 38
various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and permeable structures). It is refined and separated, most easily by boiling point, into a large number of consumer products, from petrol (or gasoline) and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals
The Political Problem A common example of a free rider problem is defense spending: no one person can be excluded from being defended by a state's military forces, and thoes free riders may refuse or avoid paying for being defended, even though they are still as well guarded as those who contribute to the state's efforts. Therefore, it is usual for governments to avoid relying on volunteer donations, using taxes and, in some countries, conscription instead. In the case of defense spending, alternative perspectives of the free rider problem also exist. A free rider may be an individual or group of military contractors, ideologues, government officials or lobbyists that inflate the risk of enemies, or even convinces the state to launch an unnecessary and expensive war, in order to sell more arms and consolidate their power. In this example, the free riders avoid all of the personal risks of
