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. Diseases such as bronchitis, lung cancer and heart diseases may all eventually appear in people exposed to a...
The Crucial Problems of the World There are many problems in the world right at this time. One of the biggest and maybe the one which people talk about the most is the waste and recycling problem. As we all know, humankind is producing more waist than we can handle, reproduce and recycle. Even in here, Estonia, people are thinking of building a nuclear power station, because fossil fuel is soon depleted. The other problem, a little bit connected to the first one, is the greenhouse effect. The light from the Sun reaches us and after that the light reflexes from the Earth's surface back to the space, but thanks to the pollution, it absorbs and reflexes back to us again, causing global warming. The third problem is the fastly growing population. There are now more than 7 milliard people in the world and the number is still getting bigger. That leads us to the overcrowded cities, poverty and hunger. ...
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.

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. Turn off the water, when you’re not using it. People often leave water running, when they’re br...
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. R...

London is the capital of both England and the United Kingdom, and the largest metropolitan area in the European Union. An important settlement for two millennia, London's history goes back to its founding by the Romans. Since its foundation, London has been part of many movements and phenomena throughout history, including the English Renaissance, the Industrial Revolution, and the Gothic Revival. The city's core, the ancient City of London, still retains its limited medieval boundaries; but since at least the 19th century, the name "London" has also referred to the whole metropolis that has developed around it. Today the bulk of this conurbation forms the London region of England and the Greater London administrative area, with its own elected mayor and assembly. London is one of the world's most important business, financial and cultural centres and its influence in politics, education, entertainment, media, fashion and the arts cont...
Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground. The average winter temperature is -28°C, but the average summe...

Temperate deciduous forest -Well-defined seasons with a distinct winter characterize this forest biome. Moderate climate and a growing season of 140-200 days during 4-6 frost-free months distinguish temperate forests. Temperature varies from -15° C to 25° C. Precipitation (750-1500 mm) is distributed evenly throughout the year. Temperate grassland- Semiarid, continental climates of the middle latitudes typically have between 25 cm and 50 cm of precipitation a year. Much of this falls as snow, serving as reservoir of moisture for the beginning of the growing season. Warm to hot summers are experienced, depending on latitude. In the winter, grassland temperatures can be as low as -40° C, and in the summer it can be as high 20° C. There are t...
Kui asi puudutab nafta ja vee segunemisesse, siis ookeanid kannatavad palju rohkema, kui lihtsalt mõningate lekete all. Kohutavad õnnetused jõuavad ajakirjandusee, aga sadu miljoneid liitreid naftat vaikselt satub merre iga aasta, põhiliselt mitte õnntuste tagajärjel. Nafta lekked põhjustavad haigusi ja tapavad Suured õnnetused ja lekked-isegi suhtliselt vähetähtis osa ookeani reostusest võib olla vägagi laastav. Sama suur kogus naftat võib teha mõnel alal rohkem kahjut kui teises kohas. Näiteks korallrahnud on nafta suhtes tunduvalt tundlikumad, kui liivarannad. Õlise ainega kaetud karvad või suled ei suuda isoleerida mereimetajat või sukelduvat lindu külmast veest ja kui loom puhastab end ta ka neelab naftat. Isegi, kui nafta kahjustus ei ole koheselt surmav võib see tekitada pikaajalist kahju. Kaladel võib see põhjustada maksahaigusi ja kasvuprobleeme. Kui nafta peaks sattuma mõningatele taimedele nt mangroovidele, siis võibsee seal...

Estonian University of Life Sciences Report on Soil Microflora By Katrin Vares Tartu 2013 Introduction The purpose of this report is to define soil microflora and establish the importance of it. Since the microorganisms clearly play an important role in preserving the balance of life, the next objective is to look into factors that influence this balance. Natural conditions and cultural impact could be considered as the variables that correlate the most with the activity and composition of microflora, hence some of the natural and cultural factors will be looked into a little more in detail. Definition, composition and importance of microflora Saunders Comprehensive Veterinary Dictionary (2007) cited by the online medical dictionary (2013) defines living microorganisms as that small that they can be seen only with a microscope and that maintain a more or less constant presenc...

Public International Law is a system of law, different from domestic law. Why is this system unique? Usually law regulates relations between people, people and the state etc, PIL regulates relations between states. Thats why PIL is important for international relation students. PIL influences the life of everybody, it doesn't regulate people directly but indirectly (through the decisions of the states), because it's everywhere. It's like air. E.g. when you want to send a letter to Brazil, you put a stamp from your own country and send it from your post office and the letter gets delivered. Why is this so easy, because there are certain international conventions that 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 ...
