Air Pollution, Water Pollution And Land Pollution

Air Pollution, Water Pollution And Land Pollution POLLUTION POLLUTION, the most commonly used word in our everyday life relating to the destruction of the natural air we breathe, the water we drink and the land we live on. No doubt the world is rapidly developing in every area possible which makes our lives much easier to live but on the other hand forgetting that we ourselves are destroying the natural resources. Many environmental researches have proved that it is because of the rapid growth in technology and other areas of growth that leads to a massive increase the growth of pollution. The unexpected pollution caused is mainly due to the human activities such as globalization, industrialization, and expanding increase in technology. This change is experienced not in a short term but in a long run, when it slowly started affecting people. Pollution can be formally defined as the undesirable and unintended contamination of the environment by human activities such as manufacturing, waste disposal, burning fossil fuels etc. The effect of pollution can be experienced in different ways. The most common ways of pollution are: Air pollution Water pollution Land pollution. AIR POLLUTION: This tern is not something new, it has been existing since he time of industrial revolution where in big chimneys are pointed out in the air which releases harmful gases into the atmosphere. This phenomenon has been increasing since then as the industries have been developing simultaneously. Today, air pollutants have shown a great effect on plantations, health and life, decreasing the enjoyment of living, rising medical costs, causes global warming and also causes the destruction of the ozone layer. One of the major causes of air pollution is the release of carbon di oxide into the atmosphere. This happens because of deforestation and fossil fuel burning. Sulfur dioxide is another main air polluter and is released into the atmosphere by the burning of sulfur containing compounds of fossil fuels. Sulfur dioxide is very harmful for the humans on high concentration and sulfur in the atmosphere is the main cause of acid rains. Chlorofluorocarbons also contribute to air pollution by reducing the ozone layer in the stratosphere. CFCs are produced by the burning of plastic foam items, leaking refrigerator equipment and spray cans. WATER POLLUTION: Contamination of available natural water by industrial wastes and other waste products can be defined as water pollution. Factors causing water pollution can be categorized into two different groups; Point sources and Non- point sources. Point sources are easy to identify and control. Some point sources of water pollution include waste products from factories, waste from sewage, waste from power plants , waste from underground coal mines and waste from oil wells. They are called point sources because these are the direct sources of water pollution and be reduced and monitored. Non- point sources are ambiguously defined and are much harder to control. The term non -point source encompasses a large range of sources like when rain and snow moves through the ground and picks up major pollutants and mover towards a major body of water, the runoff of fertilizers from farms animals and crop lands, air pollutants getting washed or deposited to earth, and storm water drained from streets parking lots and lawns. LAND POLLUTION: The contamination of and with different kinds of wastes is called land pollution. The major causes of land pollution are construction, domestic waste , industrial waste and agriculture. The rising construction of building takes away the trees that takes away the homes of the animals living there. As there are more and more people inhabiting on our planet, the demand for food increases and the forests are cut down to make farm lands. In addition, Herbicides, pesticides, artificial fertilizers and animal manure are washed into the soil and pollute it. Tons of domestic waste is dumped everyday from homes offices etc. They can be recycled or burnt in incinerators. There are still more waste machinery products such as refrigerators and washing machines that are dumped in landfills simply because they cannot be recycled. Plastic factories, oil refineries, nuclear waste disposals, and large animal farms, all lead to land pollution. WAYS TO STOP POLLUTION: We can help to reduce global air pollution and climate change by few ways: Driving a car that gets at least 35 mpg, walking, biking, and using public transportation, using CFL bulbs over incandescent bulbs, buying only energy efficient appliances, recycling newspaper, aluminum, and others, planting trees, avoid purchasing products that contains CFCs, supporting much stricter clean air laws and enforcement of international treaties to reduce ozone depletion and slow global warming.

Book: Gung Ho Essay examples -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Gung Ho, by Ken Blanchard and Sheldon Bowles was a wonderful book that discussed many important factors involved in making a company truly successful. It had a good storyline to help to tell the story of Gung Ho. When I first picked up the book to read it I really had no idea what to expect to learn from the book. The points that were made in this book were very simple and common sense principles. I say that these principles are simple, but many companies do not think of these little things when running a large business. They try to go â€Å"by the book† and get too caught up in sticking to their rules and regulations. Sometimes you just have to use a little common sense when running a business.   Ã‚  Ã‚  Ã‚  Ã‚  Gung Ho is a great idea to help a business become as successful as possible by looking at the internal workings of the company. The idea of Gung Ho starts with the most basic part of a company, the employees. If your employees are happy and excited about working at your company, then productivity will increase. Everyone will work harder for something they think is worthwhile. Take my classes and myself for example. I will be tempted to work harder and study more in a class that I think is worth my time and a class that I enjoy. Professors at Methodist College could learn a lot from this book. If they would try to make classes more enjoyable, instead of standing up and lecturing and reading straight from the book, then perhaps students would be more interested. Some of my favorite classes are with Mr. Hogge. Not because they are easy classes, because its not, but because he makes class fun with the stories and the way he teaches the material.   Ã‚  Ã‚  Ã‚  Ã‚  One of the three main principles of the book Gung Ho is the principal of â€Å"The Spirit of the Squirrel†. Two words that are very important in a business are â€Å"worthwhile work†. People will work harder at something that they think is worthwhile. The last two summers that I was in High School I was a manager in a Bar and Grille at a local golf course. I enjoyed my job and worked closely with my employees to help the Bar and Grille is successful. I attribute this very method of Gung Ho. We all worked very hard at what we did because we had a worthwhile goal. The Grille had gone through some very rough spots and had changed owners many times in the pa... ... The workers were taking great pride in their work. Something else that set them apart was their mission. They had a five-point constitution. The very first point was to protect the health, safety, and well being of every person in the department. Every other department in the factory was putting profit first in their missions.   Ã‚  Ã‚  Ã‚  Ã‚  Any business can highly benefit from the Gung Ho approach. If a business utilizes all of the methods used in the Gung Ho approach they greatly increase their chances for success. Busy golf facilities can also benefit greatly from the Gung Ho approach. This approach can help maximize productivity in what can be a hectic business. It also helps bring the different departments of a golf facility closer towards their goals.   Ã‚  Ã‚  Ã‚  Ã‚  Gung Ho was an excellent book with excellent theories on how to make a business more productive. Many of the points are already know by many businesses, however they are not know in great detail as this book describes them. This book has taught me many things in the business world and I know that I will continue to read this book and have my employees in the future read this book.

Earth Science Final

Describe the difference in stellar evolution of stars the size of our sun with that of stars 4+ times larger than our sun. Include all of the steps and the causes of each step. A nebula, an immense cloud of hydrogen gas and dust, condenses into smaller regions of matter. On occasion, one of these regions collapses under the force of its own gravitational attraction, often triggered by an outside force, like a nearby supernova-an explosion of a star. After the collapse of a cloud, atoms begin gravitating together to form a condensed center.The condensed center is a protestor. As gravity pulls in more gas and dust, pressure builds, causing the protestor core to heat up. Clouds and matter begin to rotate around the protestor and flatten due to their rotation. They surround the protestor like a rotating disk. The protestor continues to grow and its core continues to heat. When the core is hot enough, nuclear fusion begins. The start of nuclear fusion is technically the beginning of a sta r's life. Eventually, when the nuclear energy runs out, the star dies.Depending on the size and mass of the star, it can go through many stages and die in different ways-one of those ways being a supernova. . Choose a region or landscape, describe the landforms in it, the drainage pattern, how the geology influenced the landscape, and the sacrificial processes that influenced it as well. Much of the region of western New York State north of the Pennsylvania border has dendrites drainage because rock layers are flat and there are few faults or folds to divert streams.A region that has prominent parallel and perpendicular faults, repeated folds, or a strong rectangular Jointing pattern will display a rectangular drainage pattern. Anoints are cracks in bedrock along which no significant movement has occurred. They may be related to expansion or regional forces acting on bedrock. ) Streams seek the lowest areas of folds, fractured rocks along faults, or the weakest surface bedrock locat ions. Annular drainage is a pattern of concentric circles that are connected by short radial stream segments.This type of drainage occurs in an eroded dome A radial drainage pattern resembles the spokes of a wheel. Streams flow away. Climate is the other major factor in landscape development. A humid climate favors chemical weathering, which produces rounded, less angular landforms. Most of the hill slopes of New York State are rounded and gentle because f the relatively humid climate. A moist climate also allows plants to grow and protect soil from erosion. Desert areas sometimes have a stepwise profile, with flat hilltops and terraces separated by steep escarpments.The climate of New York State does not change very much from place to place. All of New York has a moist, temperate, mid-latitude climate. Therefore the landscape differences in New York State are not the result of differences in climate. The variations seen in the New York landscape are caused by geological factors. 6. Link Ocean currents and the weather conditions of 3 specific regions. In each case, describe how the weather patterns of the place are influenced by one or more ocean currents.Winds, water density and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Acropolis Effect which also influences ocean currents. Similar to a person trying to walk in a straight line across a spinning Merry-Go-Round, winds and ocean waters get deflected from a straight-line path as they travel across the rotating Earth. This phenomenon causes ocean currents in the Northern Hemisphere to veer to the right ND in the Southern Hemisphere to the left.Rica, Chile lies within one of the driest regions on Earth called the Tacoma Desert. Ocean currents keep clouds and fog Just off the coast, so most rain falls into the nearby ocean. Dethroned, Norway has a temperate climate. Summers and winters are remarkably mild for their l atitude. Rainfall is very heavy. The local harbors are free of ice most of the winter. Seattle, Washington has a mild climate with temperatures moderated by the sea and protected from winds and storms by the mountains. This area is often cloudy with light rain.

Marie Curie

She discovered the mysterious element radium. It opened the door to deep changes In the e way scientists think about matter and energy. She also led the way to a new era for medical Knowles edge and the treatment of diseases-Curie became the first woman to win a Nobel Prize and the only y woman to win the award In two different fields (physics and chemistry).Curie's efforts, with her hush band Pierre Curie, deed to the discovery of polonium and radium and, after Pierce's death, the developed NT of Grays. She was fascinated with the work of Henry Becquerel, a French physicals who discovered t hat uranium casts off rays, weaker rays than the grays found by Wilhelm Roentgen. Curie took Becquerel's work a few steps further, conducting her own experiments on uranium rays. She discovered that the rays remained constant, no matter the condition or form of the our annum.The rays, he theorized, came from the element's atomic structure. This revolutionary idea cream Ted the field of atomic phy sics and Curie herself coined the word radioactivity to describe the phone mean. Working with the mineral pitchblende, the pair discovered a new radioactive element in 1898. They named the element polonium. They also detected the presence of another radioactive material I n the pitchblende, and called that radium.In 1902, the Curies announced that they had produced a decide ram of pure radium, demonstrating its existence as a unique chemical element. With their Nobel Prize win, the Curies developed an international reputation for their scientific efforts, and they used their prize money to continue their research. Curie received another great honor In 1911, winning her sec nod Nobel Prize, this time In chemistry. She was selected for her discovery of radium and polonium, a ND became the first scientist to win two Nobel Prizes.
