Humans are changeing the planet with their ordinary life. The principle cause of climate change is the increase in carbon dioxide concentrations in the atmosphere. The main cause of that is the burning of fossile fuels. This is leading to the global warming. People have discovered a way to reduce the amount of CO2 in the atmosphere. It is possible to seperate the CO2 from the other gases by adding liquid which is very good at absorbing CO2. Then it can be pumped to underground. Scientist came up with this idea because methane gas has been down there for thousands of years and it has not come up
Black Carbon (must süsinik) Annika Pindis 10A Mis on must süsinik ja kuidas see tekib? Must süsinik on atmosfääri aerosooli koostisosa. Tekib põlemisproduktina, (eriti mittetäielikul põlemisel) fossiilkütustest, bioloogilisest kütusest, biomassist. Esineb nii looduslikest protsessidest kui ka inimtegevusest eralduva tahmana. Musta süsiniku toime Maale Must süsinik soojendab atmosfääri, kuna see on kõige suurema valguse neeldumisvõimega atmosfääris. Tahm vähendab maakera albeedot (päikesekiirguse peegeldumisvõime), muutes lume ja jääga kaetud alad tumedamaks. Mõjutab arktiliste alade jääkatte sulamist.

Green Technologies - innovation and climate change sustainagility Scientists can examine ice, but they cannot tell out anything about our future. Even if scientist has lived thousand years he won't be able to do it. The graph in video shows that the amount on carbon dioxide rises and then rises the temperature, but it is not so, it is exactly the opposite. One way to save energy is to build better buildings, because big headquarters are built to last only for 30-35 years. Building them up and pulling them down needs a lot of energy and about 30% of building energy is spent on it. It is thought that if in Tokyo 50% of all roofs are green it will save 1 million dollars a day of Tokyo businesses in cooling costs
the tundra a miserable place to be in the summer. Mosquitoes can keep themselves from freezing by replacing the water in their bodies with a chemical called glycerol. It works like an antifreeze and allows them to survive under the snow during the winter. The marshy tundra is a great place for migratory birds like the harlequin duck, sandpipers and plovers. The tundra is one of Earth's three major carbon dioxide sinks. A carbon dioxide sink is a biomass that takes in more carbon dioxide than it releases. Carbon dioxide is a greenhouse gas that contributes to global warming. During the short summer tundra's plants take in carbon dioxide, sunlight and water in the process of photosynthesis. Plants normally give off carbon dioxide after they die and decompose. But because of the short, cool summer and freezing winter temperatures, plants can't decompose. Remains of plants thousands of years old have been found in the tundra permafrost

interesting applications for this gas which appeal to people who are interested in sustainable energy and the health of the environment. The basis for biogas is organic material such as food scraps and feces which are held in an anaerobic area, which can range from a storage tank which is not ventilated to a device which is specifically designed to produce gases. The conditions attract anaerobic bacteria, which start to break down the organic material, producing methane and carbon dioxide as a by-product. Another type of biogas which includes hydrogen, nitrogen, and carbon monoxide can be obtained through the gasification of biomass such as wood or rice husks, a technique which is used to manufacture gas industrially. The gases produced through anaerobic fermentation or gasification are combustible in addition to having a strong smell which makes them stand out to the human nose. Methane leaks from landfills are an ongoing problem, as is the
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 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

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 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
Acid Rain Acid rain is any precipitation that is unusually acidic. It possesses elevated levels of hydrogen ions(it has low pH level). 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

The soil microflora largely depends on the type of soil, temperature, moisture, plant growth, nutrients, pH, and many other factors which may vary between locations but also within a single plot and over very small distances (OECD, 2007). Nevertheless of the quantity of microflora, biomass of all microorganisms living in soil play an important role in the functioning of entire soil ecosystems because their enormous biochemical activity (Barabasz et al. 2002). Soil microflora cycles carbon, nitrogen, phosphorus, and sulfur, plays a role in soil structure formation, decomposition of organic matter, toxin removal, promoting plant growth, and in changes in vegetation (Canbolat at al. 2005 and Martin et al. 2012). Therefore, soil microflora plays a major role in preservation and the balance of life. Because of active role of soil micro- population, the diminution in microbial activity is always alarming (Barabasz et al. 2002). Factors influencing soil microflora

With global warming adding to it, it's only going to get worse and worse. Furthermore, warmer temperatures would widen the range of disease carried by rodents and mosquitoes. This increase of temperatures is happening at a pace that outstrips anything the Earth has seen in the past 100 million years. We have caused all of this over many years of over industrialization in this growing world. Many different things cause the greenhouse effect. The amount of carbon dioxide in the atmosphere is increasing because of the massive consumption of fossil fuels such as oil, coal, and natural gas. Another contributing factor is the the amount of forest logged. Every second of the day the area of a football field in trees is cleared by either being logged or burnt. The potential costs of cutting down on greenhouse gas emissions might sacrifice economic growth and our standard of living. By doing this we might need to change our habits and behavior
I talking about that, why horse would be better than car. With horse you can run on everywhere, without damaging the ground. A horse dont need any fuel like cars, only food, water,and some vitamins. Horse does not emit toxic lead or carbon monoxide which can cause diseases on people and animals. But with horse you cant drive so fast and long distances like with car. Horse causes no traffic jam, he does not need to be managed traffic light since it travels with much slower speed and can stop faster than car. But of horse you must take more care than car. Car may stay in garage a long time, nothing happening with that, but horse often needs food and takeing more care.

petroleum is converted into energy-rich fuels (petroleum-based fuels), including petrol, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas. The lighter grades of crude oil produce the best yields of these products, but as the world's reserves of light and medium oil are depleted, oil refineries are increasingly having to process heavy oil and bitumen, and use more complex and expensive methods to produce the products required. Because heavier crude oils have too much carbon and not enough hydrogen, these processes generally involve removing carbon from or adding hydrogen to the molecules, and using fluid catalytic cracking to convert the longer, more complex molecules in the oil to the shorter, simpler ones in the fuels. Due to its high energy density, easy transportability and relative abundance, oil has become the world's most important source of energy since the mid-1950s. Petroleum is

Solar panels are used to collect sunlight. Solar panels are made up of photovoltaic cells that convert the sunlight into energy. Why do we need it? How does it lead to better health? Solar power is source of clean energy. It does not produce pollution or greenhouse gases or carbon compounds. Solar power would be a lot safer for the environment and a lot better for the health of people. What would happen if we don't use solar power? If we don't start using solar power, we would use oil and coal. They produce pollution and will cause millions of people to suffer from respiratory related problems. The oil and coal will run out and people will have to resort to other ways of power. Solar energy Karol Pakkas

to reduce them and do their bit for the environment. Here’s a list of LOVE AND CARE THE ENVIRONMENT important topics and with them a list of big ways that you can help. LEAVE YOUR CAR AT HOME Every time you drive, you're adding more than 1.5 pounds of carbon dioxide or other greenhouse gases to the environment with each mile. Change your driving habits and you make an immediate impact on the environment. Take short trips on foot or by bike instead, and you'll also make an immediate impact on your health. While riding your bike at a leisurely 6 miles per hour, you can burn 240 calories an hour or more. Walking at a normal pace of 2 to 3 miles per hour, you can burn up to 300 calories or more each hour. Choose Locally Grown or Organic Food
atmosphere, which causes the damaging of the environment, human health and the quality of life. Firstly, we should use green methods of powering like wind energy and landfill gas energy. This would reduce the amount of harmful gases. Another useful suggestion would be to plant trees. In this way we can increase the source of breathable oxygen. Unfortunately, many companies are contributing to deforestation. Finally, it would help if we put taxes on carbon emissions or higher taxes on gasoline. In this way people and companies will have greater incentives to conserve energy and pollute less. In conclusion, there are many ways to pollute the air less. We all have to do whatever we can to solve this major problem. As Shimon Peres said “If a problem has no solution, it may not be a problem.”

Importance of tourism to countries such as Egypt, Greece and Spain can not be questioned, as employment, service industry and opportunity to sell goods, is related to it. Tourism has also helped to build up certain regions, which otherwise would still be struggling in poverty. Futhermore, to make country desirable destination, governments have to keep crime rate under control, which makes life safer for locals as well. On the negative side, relentless waves of tourists increase our carbon footprint. Transportation increases pollution and creates gridlocks. Often big hotels consume unreasonably large amount of water, while locals are left in dry. And after all, tourist are not the ones who suffer from the effects, locals are. Tourism has its positive and negative sides. It is important part of today's economy, as many countries live of it, but it also has darker side. It is important to remember, that when tourist leave the destination, locals will still be living there.
AVON, CT SNOWSTORM THE CATSKILLS, NY HURRICANE JOPLIN, MO TORNADOES video TUSCALOOSA, AL TORNADOES NASHVILLE, TN - FLOODING HISTORY Story begins in the early 1920s with an inventive scientist named Samuel Ruben and Philip Rogers Mallory During World War II, for instance, Ruben devised the mercury cell, which packed more capacity in less space and was durable enough for the harsh climates of wartime theaters like North Africa and the South Pacific--places where ordinary zinc carbon batteries used in flashlights, mine detectors, and walkie-talkies couldn't hold up. P.R. Mallory manufactured millions of mercury cells for the war effort. The Mallory Battery Company was formed shortly thereafter. And in 1950s they improved that battery, making it more compact, durable, and longer lasting. And now they are the world's leading producer of high-performance alkaline batteries.

Essay. Is global climate change (global warming) man-made or not? Over the last hundred years the Earth has been warming. This warming is believed to lead to many issues such as increasing of nature disasters, weather changes and draught. All of these consequences could become a reason of economic decay in many countries, especially in some undeveloped countries. Therefore it is very important to find out who is guilty of the climate changing. Many people are confident that the reason of global warming is man made carbon dioxide. Over the last hundred years our society has been developing very fast: there has been built a huge amount of different factories, has been made so many inventions in all fields of human activity. Unfortunately only recently we have noticed that by making our life more comfortable and more enjoyable we destroy nature and cause appearance of ozone holes wh...

deforestation due to land-use changes. A study (Lapola et al., 2009) concluded that in the future, soybean production is likely to be a cause of a direct deforestation in Amazon. It will also be responsible for 60% of indirect deforestation as rangelands will be moved to Amazon region due to the competition for land in other areas (Lapola et al.,2009). 4. Other sustainability concerns 4.1. Greenhouse gas (GHG) balance One of the advantages for adopting biofuels is the offsetting of carbon in the production process. Biofuels are carbon neutral when their combustion doesn't release any more carbon dioxide into the atmosphere, than was sequestered by the plant through photosynthesis (Rajagopal, Zilberman, 2007). Nevertheless, there are many uncertainties around the biofuels' carbon neutrality. In the production process, biofuel require significant amounts of energy for tillage, fertilizers, pesticides, irrigation and for harvesting. Nitrogen oxide from fertilisers are
Erinevate sihtotstarvetega süsinikkiudude valmistamiseks kasutatakse erineva päritoluga pigiliike ja erinevaid valmistamismeetodeid. Igal neist on omad eelised ja puudused, kuid eelistatakse ikkagi protsesse, mis võimaldavad kiiremini soovitud tulemini jõuda. Selleks, et tootmine oleks kiirem ja tõhusam, on välja töötatud erinevaid võimalusi süsinikkiudude valmistamiseks pigist, millest mõningaid ka selles referaadis tutvustasin. Kasutatud kirjandus: 1.

exhausting. Many parents have lost their jobs because of the virus. And still there are people who won’t listen to the government rules and spread the virus further. Secondly, global warming is increasing at an alarming rate with the progress in technology. In recent years, industrialization and extensive use of automobiles have been observed, and these developments have significantly raised the levels of greenhouse gases in the atmosphere. Moreover, these gases like carbon dioxide and methane trap the sunlight and elevate the temperature of the earth. This change in temperature is not only responsible for global warming but also other associated problems of climate change and air pollution. In conclusion, to ensure positive contributions and to minimize risks to the planet, relying on govenment alone will not lead to the desired results. Each person's effort can effectively help protect the environment.

vastust ,või teda lihtsalt teavitatakse. Seega tasub kirja kirjutamisel vaadata, millisele väljale saaja või saajate meiliaadressid on märgitud ja kirja saajana pöörata tähelepanu, millisel väljal on Sinu nimi. · TO on saaja(d) ehk adressaat, kellele meil on suunatud. · CC (Carbon Copy) - meili koopia saaja. Edastatud teabe saamiseks, sest see ei nõua otseselt vastust. · BBC (Blind Carbon Copy) salakoopia saaja, kes saab meili teadmiseks.(To ega CC ei tea ,et ka BBC-le on kiri saadetud) Proovi kirjale vastata esimesel võimalusel, vaikimine võrdub samaga, kui me näost-näkku suhtlemisel pöördume inimese poole ja ta meist välja ei tee. Seetõttu on oluline meilidele vastata ja teha mõlemale poolele sobivad kokkulepped meilivahetuses, millega mõlemad ka arvestada saavad. Oluline on ,et meili saatja saaks tagasisidet, et meil on kenasti temani jõudnud
composition. Because of these similarities, it was thought that Venus might even have life. Venus is also called the Morning star or the Evening star, because it reaches its brightness shortly before sunrise or shortly after sunset. It is the brightest object in the sky except for the Sun and the Moon. During the last few years the scientists have found that Venus and Earth are very different. It has no oceans and is surrounded by a heavy atmosphere composed mainly of carbon dioxide with virtually no water vapor. There are strong winds at the cloud tops but winds at the surface are very slow, no more than a few kilometers per hour. The surface of Venus retains a constant temperature between day and night and between the equator and the poles. We can't see the surface of Venus from Earth, because it is covered with thick clouds that strongly reflect sunlight. However, space missions to Venus have shown us that its
