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
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. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food
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
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 third of the United States and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan 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
PH is the scale measuring the amount of acid in the water and liquid. The pH scale ranges from 0 to 14 with lower pH being more acidic while a high pH is alkaline; seven is neutral. Normal rain water is slightly acidic and has a pH range of 5.3-6.0. Acid deposition is anything below that scale. It is also important to note that the pH scale is logarithmic and each whole number on the scale represents a 10-fold change. Causes and History of Acid Rain Acid deposition can occur via natural sources like volcanoes and rotting vegetation but it is mainly caused by the release of sulfur dioxide and nitrogen oxide during fossil fuel combustion. When these gases are discharged into the atmosphere they react with the water, oxygen, and other gases already present there to form sulfuric acid, ammonium nitrate, and nitric acid. These acids then disperse over large areas because of wind patterns and fall back to the ground as acid rain or other forms of precipitation.

...................................................................60 17.3 How Does Oil Impact The Environment?................................................................60 3 ENERGY STORY Once upon a time, in a town not far away, there was an 8th grader who was afraid of the dark. Her name was Jules. She was also afraid of the quiet, and of the cold. So she always left on the lights, the TV, and stereo even when she had her I-Pod earbuds on. She took lots of very long, hot showers. She never walked anywhere, but got rides from her mom in a big SUV. She couldn't be happy unless she was using all the energy she possibly could for all the stuff around her. Her friend, Les, didn't like to use any energy at all. He walked to school, read books instead of watching TV, played the trumpet instead of Guitar Hero, and turned off the lights anytime he left a room. Then one evening, there was a power outage
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
It is energy released by the splitting (fission) or merging together (fusion) of the nuclei of atoms. The conversion of nuclear mass to energy is consistent with the mass-energy equivalence formula E = m.c², in which E = energy release, m = mass defect, and c = the speed of light in a vacuum. Nuclear chemistry can be used as a form of alchemy to turn lead into gold or change any atom to any other atom (albeit through many steps). Radionuclide (radioisotope) production often involves irradiation of another isotope (or more precisely a nuclide), with alpha particles, beta particles, or gamma rays. Iron has the highest binding energy per nucleon of any atom. If an atom of lower average binding energy is changed into an atom of higher average binding energy, energy is given off. What is nuclear fusion? Nuclear fusion is the process by which multiple like- charged atomic nuclei join together to form a heavier nucleus
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.

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. There is made lot of campaigns, spend lot of money and so on. But quite big proportion of people does not care about it and think it is only wasting their time. Also they think that even they attend in this campaign, it change nothing.

The term Dioxin is commonly used to refer to a family of toxic chemicals that all share a similar chemical structure and a common mechanism of toxic action. Most dioxins and furans are not manmade or produced intentionally, but are created when other chemicals or products are made. This family includes: seven of the polychlorinated dibenzo dioxins (PCDDs), ten of the polychlorinated dibenzo furans (PCDFs) and twelve of the polychlorinated biphenyls (PCBs). · PCDD · 2,3,7,8TCDD · PCDF · PCB · PCDDs and PCDFs are not commercial chemical products but are trace level unintentional byproducts of most forms of combustion and several industrial chemical processes.

ENVIRONMENTAL PROBLEM The term acid rain refers to what scientists call acid deposition. It is caused by airborne acidic pollutants and has highly destructive results. Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natural causes as well
The problems the contemporary world faces Over Loorits LE108 Pollution Air pollution produced by industry and motor vehicles. Water pollution caused by chemicals and sewer water dumped into water. Soil pollution caused by chemicals released into underground lakes. Natural resources running out Rainforests are being cut down constantly. There are not enough fresh water in some parts of the world. Fossil fuels are used too much and most of its reserves will be used up by 2050. Endangered species 40 percent of all organisms are endangered All the different species are important for biodiversity Habitat loss and hunting are the most widespread cause of species endangerment .

Air pollution in Japan Birgit Tohter Air pollution The presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk. The effects of air pollution is global warming, heart problems, acid rains etc. There are solutions like public transport, cleaning smokestacks, laws, renewable sources, The history Industrial activity in Japan devoloped rapidly after the World War II. People became really sick and described it as more horrible suffering than death. In the 1970s Japan managed to clean up without sacrificing growth by investing in pollution-control technologies. They made new laws. It was the start of "Japan's Pollution Diet". Today, Japanese cities are among the world's least polluted, according to the World Health Organization. Air pollution in Japan
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.
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

Formaldehyde Formaldehyde is a colorless, flammable gas at room temperature. It has a pungent, distinct odor and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. Formaldehyde is also known as methanal, methylene oxide, oxymethylene, methylaldehyde, and oxomethane. Formaldehyde can react with many other chemicals, and it will break down into methanol (wood alcohol) and carbon monoxide at very high temperatures. Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin. A major source of formaldehyde that we breathe every day is found in smog in the lower atmosphere. Automobile
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. The nation's land pollution problems are
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. In witness of it is appearance of blue seaweeds. In my opinion these thing is very
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.

population, distribution and their activity in the soil are: 1. Natural conditions (including soil fertility, pH, aeritation, temperature, moisture, organic matter, food and energy supply, microbial association and interactions) 2. Cultural practices These factors play a great role in determining not only the number and type of organism but also their activities. Variations in any one or more of these factors may lead to the changes in the activity of the organisms which ultimately affect the soil fertility level. Natural conditions Extreme environments such as high-altitude and highlatitude ecosystems are very sensitive to environmental changes. Global warming is hypothesised to alter both above- and below ground processes affecting the soil ecosystem (Asher et al. 2012). As an example, Asher et al. (2012) further proved in their research on humus creation that thermal conditions (due to
How can we reduce air pollution levels in our cities? Are our cities clean and fresh enough? Unfortunately people don't see that actually cities aren't clean enough. The Aair pollution is growing every day, but how can WE change it? Firstly, we should watch out for the garbage we produce. Many things that are thrown away can be recycled, but some of the people aren't aware of that. They throw things away which may be dangerous for nature. Another solution is to use more buses and bicycles. Every family member doesn't need his/her own car. When you move more in fresh air, you will feel better yourself, your health will be better and you will reduce air pollution levels. Finally, big-factory owners should pay attention where they build on their factories. I think that it is very important that they don't build them in the middle of cities. The pollution twhat comes from the factories is bigdrastic. In conclusion, there are many ways to make our cities' air pollution levels lo
[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 term "acid rain" was generated in 1972. [5] Canadian Harold Harvey was among the first to research a "dead" lake. Public awareness of acid rain in the U.S increased in the 1970s after the New York Times promulgated reports from the Hubbard Brook Experimental Forest in New Hampshire of the myriad deleterious environmental effects demonstrated to result from it. Occasional pH readings in rain and fog water of well below 2.4 have been reported in industrialized areas.[2] Industrial acid rain is a substantial problem in Europe, China,[8][9] Russia and areas down- wind from them. These areas all burn sulfur-containing coal to generate heat and electricity.[10] The problem of acid rain not only has increased with population and industrial growth, but has become more widespread
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 result, we can save many aquatics and other animals, who use lake or river water for drink. We all know that currently very active business"recycling" has been save pollution of the trash what doesn't decomposist or need many years for that. If people continue with this same active then wild animals are rescued.
For example McDonald`s and Burger King are not using plastic straws anymore. Second thing that affects the life on Earth is overpopulation. The estimated population in 2050 is near 10 billion. Population growth also raises overconsumption. People are encouraged to consume by companies and their commercials. The problem is that humans are consuming more than the Earth can regenerate. The exhaustible resources are running out. And with the population growing, it will become an even bigger probleem. This means people in the future may not have enough resources, because right now humans are using too much. Another huge problem is global warming. The effects of global warming can already be seen today. Half of the Great Barrier Reef already dead because of the increasing temperature. Global warming causes a lot of species to go extinct. It also causes extreme weather conditions. Rising temperatures may lead to droughts and increase wildfires. If people don not

the awe-inspiring experience of standing in the heart of a primary rainforest. Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources that for eons, by virtue of their richness in both animal and plant species, have contributed a wealth of resources for the survival and well-being of humankind. These resources have included basic food supplies, clothing, shelter, fuel, spices, industrial raw materials, and medicine for all those who have lived in the majesty of the forest. However, the inner dynamics of a tropical rainforest is an intricate and fragile system. Everything is so interdependent that upsetting one part can lead to unknown damage or even destruction of the whole. Sadly, it has taken only a century of human intervention to destroy what nature designed to last forever.
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
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.
