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

Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing
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
In 2006, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood-burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation),followed by solar hot water/heating, which contributed 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.8% of final energy consumption. While there are many large-scale renewable energy projects and production, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.Kenya has the world's highest household solar ownership rate with roughly 30,000 small (20100 watt) solar power systems sold per year. Some renewable energy technologies are criticised for being intermittent or unsightly, yet the market
ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. 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
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
history, etc? It is obvious that such skills are more valuable than any single subject which might be used as the vehicle to develop them. Inequality. Some students, subjected to identical classwork, learn rapidly and progress, while others fail. How can we predict success or failure, and compensate the at-risk children? Few practical options may be available to teachers. It is inevitable in universal public schooling that the extreme students, either dull or bright, will be hurt by our emphasis on the average. It is horrible to admit, but our society cannot assume that all members are capable of being well educated. We have unequal physical, mental and environmental status, and the poorer fringe will always exist. Those of us lucky enough to have a conscience, mature enough to see how things really are, must do what we can to help the less fortunate. Obligation to help. How can a rich person help a poor one? By giving some money? Well,
Air pollution Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Air pollution has been a problem throughout history
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 summer temperature is 3-16°C. During the brief summers, the top section of the soil may thaw out allowing plants and microorganisms to grow and reproduce. However, these plants and microorganisms become dormant during the cold winter months. Soil is formed slowly. The constant freezing and thawing in the tundra helps to break the rocks into smaller pieces. Permafrost consists mostly of gravel and finer material
To begin with, everyday life has been disturbed because of COVID-19. Life stopped during this pandemic not only in China where it started, but also across the globe. When we look at the present situation, very many people are confined to their own homes. In Estonia, students can’t go to school normally, they have to stay behind the computer every day and it is very 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
Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of 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
had been just recently discovered at the time 1895. 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-
Margit Tepner k0848752 Sustainability aspects of biofuels 1. Introduction The literature review will discuss the sustainability aspects of biofuels. Food production will be the main concern as it is the most debated issue, but other aspects, such as land use change and water consumption will be also considered as they are essential aspects in the biofuels sustainability criteria. The review will discuss the viability of biofuels based on the current technologies. Second-generation biofuels are not yet commercially viable and therefore will not be discussed; although they could significantly improve the sustainability of biofuels when they break through to the industrial scale. 2. The scale of biofuels production 2.1
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
....................................................................184 Notes...........................................................................................................186 About the Author........................................................................................189 CHAPTER ONE THE FLOWERING OF HUMAN CONSCIOUSNESS EVOCATION Earth, 114 million years ago, one morning just after sunrise: The first flower ever to appear on the planet opens up to receive the rays of the sun. Prior to this momentous event that heralds an evolutionary transformation in the life of plants, the planet had already been covered in vegetation for millions of years. The first flower probably did not survive for long, and flowers must have remained rare and isolated phenomena, since conditions were most likely not yet favorable for a widespread flowering to occur. One day, however, a critical threshold was reached, and suddenly there would have
Acid rain 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. Recently, more
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

PSYCHOLOGY PART 1: CORE Biological level of analysis Outline principles that define the biological level of analysis. 1) Behavior can be innate, because it is genetically based. Evolution may play a key role in behavior. 2) Animals may be studied as a means of understanding human behavior. 3) There are biological correlates of behavior. Cognitions, emotions and behaviors are products of the anatomy and physiology of our nervous and endocrine system. Explain how principles of the biological level of analysis may be demonstrated in research. 1) Correlational studies: Study by Buss, who hypothesized that across cultures, men will prefer to marry younger women because of greater reproductive capacity and women will place greater value on a potential mate's earning
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. Through buffoonery, utter mismanagement and downright stealing of the wealth of the masses, these leaders have so impoverished Africa that we are now nothing but a beggar continent. We beg for
1. Bacteria a) Heterotrophic bacteria, eg. symbiotic and non - symbiotic N2 fixers, ammonifier, cellulose decomposers, denitrifiers b) Autrotrophic bacteria, eg. nitrosomonas, nitrobacter, sulphur oxidizers, etc; 2. Fungus; 3. Viruses 4. Actinomycetes and stretomyces; 5. Algae eg. BGA, yellow gree algae, golden brown algae. 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

Kati-Liis Karu 03.01.2011 The euro in Estonia Joining the European Union in 2004 made people in Estonia think about the changing of currency. We had almost six years to get used to the fact that the Estonian kroon is eventually going to end. In that time there was a lot of discussion about whether we should stick to the kroon or change our money to the euro. Lots of people were afraid that they lose their money during the period of transition - this belief was quite popular among people who still remember the time when the Russian rubles were changed into kroons and did lose much money. Luckily there haven't been any complaints yet. The reason I chose this political concern is its contradictoriness. I myself dislike the fact that the kroon is "leaving us" but I hope that in the long run it will seriously benefit us
"I am become death, the destroyer of worlds." So said the physicist Robert Oppenheimer, who helped to invent the atomic bomb. The two bombs dropped on Hiroshima and Nagasaki in 1945 killed around 200,000 Japanese people. No other species has ever wielded such power, and no species could. The technology behind the atomic bomb only exists because of a cooperative hive mind: hundreds of scientists and engineers working together. The same unique intelligence and cooperation also underlies more positive advances, such as modern medicine. But is that all that defines us? In recent years, many traits once believed to be uniquely human, from morality to culture, have been found in the animal
