THE LUNGS OF THE EARTH

I Introduction :
Forests are the lungs of the earth. Thus, we can see the importance of forest towards the living things as the forest contribute in supplying most of their needs, maintaining the world climate, and preventing catastrophic consequences to the environment.

II Body : A. Forest and all living things complement each other as forests is important in supplying the needs of life. 1. Forest will produce oxygen and absorb the carbon dioxide. a) Oxygen released by the trees in the forest is the chemical gas that are very important to human and animal life.(Chrisz,2006) b) Trees absorb carbon dioxide in the air and replaced it with clean air to remove toxic gases that facilitate human and animal respiration. 2. Supply various kind of food. a) Forests serves as the largest supplier of food and herbal plants that are important to humans, animals and in the medical field.(Chinery,2001) 3. Provides different kind of wood for many purposes. a) Wood being used as fuel because it creates less smoke and burns longer. b) Teak wood is used as house building materials as well as in the furniture industry.(Col,2006)

B. Another importance is in maintaining the world climate. 1. Decreased the thinning of ozone layers. a) Oxygen from trees is the main part of ozone creation that will protect earth from sunlight radiation and meteors fall.(Silverswan,2010) 2. Protects the earth from global warming. a) Forests absorb carbon dioxide, one of the poisonous gas that makes the earth warmer. b) Water vapour is released by trees into the air to cool the air temperature. C. One other importance is in preventing catastrophic consequences to the environment. 1. Prevent landslides a) Highland forest slows down the flow of rainwater down the…...

The Lungs of the Earth

...The earth has generously provided us with so much, yet we unthankful humans damage and destroy it. One of the majorly affected places on Earth that suffers from this untamed destruction is the forests. I strongly agree that destruction of forests will eventually lead to the demolition of the Earth. Of the 30 million known species on the Earth 28 million are found in rainforests. These species belong to theses forests; it is their natural habitat which we are annihilating by deforestation. These animals without their natural habitat will not be able to survive. One of the major causes of global warming is deforestation. The huge amounts of carbon emission for our factories and cars are released into the atmosphere. The plants and trees, which inhale the excess carbon dioxide being released, are now being cut and global climate change will soon reach its peak. Also, in these forests a lot of mining takes place due to deforestation. And this mining causes many rivers and lakes to get polluted. This can affect the wild life in sea as well, which can be very alarming. Nevertheless, one must balance the argument and take a look at the other side. Some people say that we need to clear these fields to build upon them. This will increase our standards of living. My response to that would be, that with climate change on the increase what is the need of the improvements in quality of life? What is the whole point, when we are ruining so many habitats? Are we humans that self-centred...

...Wang Lung’s Character in The Good Earth as a Typical Farmer Image in China Abstract Pearl Buck, who lived in China for almost 40 years, has formed an in-depth understanding of Chinese society and owned a spontaneous emotion toward Chinese people. With a meticulous and direct observation of Chinese farmers, she accurately grasped “earth” as the survival core and cultural root of Chinese farmers. In her masterpiece, The Good Earth, Pearl Buck brings authentic rural life and vivid images of farmer in China to western readers through her unique perspectives. The Good Earth not only changes distorted stereotype Chinese images in the westerners’ mind in 19th century, but also fully demonstrates various Chinese farmer’s characters. This thesis intends to analyze Wang Lung’s behavior and his hidden characters as a typical farmer in China. Through scrutinizing the text content, the author discovers that both merits of traditional Chinese farmer and backward thoughts under the feudal society are embodied in Wang Lung’s character. On the one hand, Wang Lung, industrious and frugal, simple and kind, has a keen attachment to earth. On the other hand, he is feudalistic, timid and conservative with a strong lust to women.

Ozone Depletion

...Running Head: OZONE DEPLETION Taylor Graham Ozone Depletion The Ozone Layer The ozone layer prevents most harmful solar ultraviolet light, (UV) from passing through the earth’s atmosphere by absorbing 93-99% of these UV rays. UV rays are potentially damaging to life on earth. The ozone layer is comprised of high concentrations of ozone, (03) and mainly located in the lower portion of the stratosphere (rabbitair.com). The atmosphere of the Earth is divided into 5 layers. From closest and thickest to farthest and thinnest the layers are: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The majority of the atmosphere’s ozone resides in the stratosphere, which extends from 6 miles above the Earth’s surface to 31 miles (Sivasakthivel, 2011). The density of the ozone varies according to the season and also the location. The ozone layer has historically protected the Earth from the harmful UV rays, however in recent decades this protection has diminished due to stratospheric ozone depletion. History of Ozone Depletion Ozone depletion is largely a result of man-made substances. Humans have introduced gases and chemicals into the atmosphere that have rapidly depleted the ozone layer in the last century. The possibility of ozone depletion was first introduced by scientists in the late 1960's as dreams of supersonic transport began to become a reality. Scientists had long been aware that nitric oxide (NO) can catalytically react with ozone (O3) to......

The Good Earth

...Irony in the Good Earth Irony plays a major part in the novel, The Good Earth by Pearl S. Buck. Authors often use irony in their writings to show contrast between what is said or what is meant, and what really happens. There are many different examples of irony throughout the book. The displayed irony includes: Wang Lung, money, and sons. These three topics are perfect examples of the use of irony in this novel. When the main character, Wang Lung, first started out in the novel he was a poor farmer awakening to his wedding day. At this point, Wang Lung was very sensible about money and lived in an earthen house on his land. Wang Lung married O-Lan, a slave that lived in the Great House of Hwang. He was treated poorly and unequally by the Great family and he never would have thought he would later come to live in the Great House. Sure enough, his fortune changed and Wang became a rich man and his family became much like the Great family. Wang Lung became slightly careless with his money, but with the persuasion of his sons, he purchased the Great House later on in the novel. “I could sit on that seat where the old one sat and from whence she bade me stand like a serf, and now I could sit there and so call another into my presence” (Buck 288). Truly this is a great rags-to-riches story and this is ironic because once he was a poor farmer looking up at the Great house, and later he owned it. “Now Wang Lung, as this hour drew near stayed more and more in the house in the...

Pollution

...they all result in the same thing, earth is slowly dying. Pollution is harmful to both the environment and the creatures that inhabit it, including humans. If you are wondering what the most harmful causes of pollution are, look no further, because you should consider the terrible causes of air pollution, sewage, and oil spills, as well as the effects that they have on the environment. Air pollution is one of the most common ways that the earth is polluted. Air pollution is caused by many things including exhaust fumes from cars, manufacturing factories and the household and farming chemicals. The fuel that is used in cars includes fossil fuels, which emit carbon dioxide into the air, causing global warming. Power plants also burn oil and coal, which releases poisonous gases into the air, which may result in acid rain. Air pollution effects many people across the world as well as the environment. “Health experts have known for years that air pollution increases the risk of a wide range of ailments, including respiratory problems and heart disease. Some compounds in the air we breathe, such as diesel exhaust, have already been deemed cancer-causing.” (Barboza). It is not only a major risk to health, it’s also a leading environmental cause of cancer death. There were 220,000 people that died of lung cancer due to air pollution in 2010 in China. Though you may not think of it, sewage is a major pollutant as well. Pipes under the earth take the sewage from homes to......

Causes of Global Warming

...Adryen SEKA 10/09/2015 ENGL-121 Instructor: Yu Bai Topic: The causes of global warming Climate changes are not new. The studies conducted by the researchers show that global temperature during the prehistoric times was generally warmer than today except during the 5 ice ages. Changes in our climate are indeed as old as our planet earth. However, global warming is one of the biggest issues of the twenty first century. Many researchers, scientists, and environmentalists are expressing concerns about changes on the climate on earth. Some believe that the climate is becoming abnormally warmer an issue which is referred as “global warming”. That’s why the major part of the world comes together to discuss about what are the causes and which impact they have on the life on earth. More and more countries are joining the meeting to discuss about how to define new restrictions to prevent and slow down the global warming. The surface of the earth which is warming up is not without consequences. Indeed some negative effects of the global warming have a heavy impact such as the rise in sea levels, less precipitation, expansion of the desert retreat of glaciers and sea ice. All these effects have their own consequences and there are many reasons which explain this global warming. Overpopulation, deforestation and burning of fossil fuels are listed as causes of the global warming. Fifty years ago the world population was about 3.7 billion with an emission of fossil fuels of 14......

Radon in Domestic Dwellings

...Brenner ,1989).Radon is undetectable to humans through their senses. Radon has also been present geologically on the earth for as long as the earth has been formed and was discovered by a German chemist Friedrich Ernst Dorn in the 1900’s, and is found with the noble gases on the periodic table. Because radon is a gas it can seep through rocks and it is suggested by (Scivyer, 2004) granite areas tend to disperse more radon in to the air and homes. Radon progeny get in to the Epithelial lining of the lungs by respiration via air containing radon and irradiate tissue. Radon is an alpha particle which causes further damage to the lungs resulting in possible Lung Cancer or a higher risk to a smoker or non-smoker. Radon is a carcinogen suggested by (Cancer Research uk, 2012). According to the ( S, Darcby , et al 2009) “Each year around 1,100 deaths from lung cancer (3.3% of all deaths from lung cancer) are related to radon in the home” this is also stated by (Public Health England, 2013). These statistics suggest that there is a risk to public health. The mass of radon caused cancers are usually low to medium concentrations as opposed to high concentration due to the fact that largely in the UK people are not exposed to very high doses depending on location. Also there are no suggestions as to precisely known threshold which radon poses no risk with regards to lung cancer (WHO, 2005). Radon changes over time stated by the ( Health Protection Agency,......

Air Pollution

...global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Carbon dioxide, a greenhouse gas, is the main pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. In the past 150 years, such activities have pumped enough carbon dioxide into the atmosphere to raise its levels higher than they have been for hundreds of thousands of years.1 Other greenhouse gases include methane, which comes from such sources as swamps and gas emitted by livestock, and chlorofluorocarbons (CFCs), which were used in refrigerants and aerosol propellants until they were banned because of their deteriorating effect on Earth's ozone layer.1 Another pollutant associated with climate change is sulfur dioxide, a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and causes Earth to cool. Volcanic eruptions can spew massive amounts of sulfur dioxide into the atmosphere, sometimes causing cooling that lasts for years. In fact, volcanoes used to be the main source of atmospheric sulfur dioxide; today people......

...Pearl S. Buck’s The Good Earth is about a farmer, Wang Lung, who experiences times of poverty and prosperity throughout his life; however, to summarize the book in one sentence is to do a great disservice to it. One of the novel’s recurring themes is that of beauty. The book takes place in China in the late 19th or early 20th century. Time has changed our world in many ways since then. Has time changed the meaning of beauty? Is there a difference in how the Chinese and Americans see beauty? Do we perceive beauty in different ways than the people in the time of The Good Earth? I conclude that the ideals of beauty have changed since the book was written and that modern American society has taken on new views of what it means to be beautiful. Men and women today can use cosmetics as part of a regular beauty routine to achieve certain beauty standards and to increase confidence. Throughout the last century in America, the very meaning of beauty has changed very often: from the Gibson Girl in the early 1900s to the flappers in the 1920s, from the full-figured pin-up girls of the 1940s and the 1950s to the “heroin chic” waifs of the 1990s, what the western world considered beautiful changed with each decade. When one considers beauty, it is now most likely physical appearance that comes to mind. Hilhorst notes, “The view that physical beauty can be conceived of as a value in its own right is, however, a modern thought.” Hilhorst explains in “Physical Beauty: Only Skin Deep...

...still except for the faint, gasping cough of his old father, whose room was opposite to his own across the middle room. Every morning the old man's cough was the first sound to be heard. Wang Lung usually lay listening to it and moved only when he heard it approaching nearer and when he heard the door of his father's room squeak upon its wooden hinges. But this morning he did not wait. He sprang up and pushed aside the curtains of his bed. It was a dark, ruddy dawn, and through a small square hole of a window, where the tattered paper fluttered, a glimpse of bronze sky gleamed. He went to the hole and tore the paper away. "It is spring and I do not need this," he muttered. He was ashamed to say aloud that he wished the house to look neat on this day. The hole was barely large enough to admit his hand and he thrust it out to feel of the air. A small soft wind blew gently from the east, a wind mild and murmurous and full of rain. It was a good omen. The fields needed rain for fruition. There would be no rain this day, but within a few days, if this wind continued, there would be water. It was good. Yesterday he had said to his father that if this brazen, glittering sunshine continued, the wheat could not fill in the ear. Now it was as if Heaven had chosen this day to wish him well. Earth would bear fruit. He hurried out into the middle room, drawing on his blue outer trousers as he went, and knotting about the fullness at his waist his girdle of blue cotton cloth. He left......

Monstrous Dawn of Progress

...time--thus, it makes them more invincible to the dangers of their natural environment. In contrast with these, we try to colonize our indigenous people and force them to live our own way of living without thinking that they could not handle the fast phasing of our daily living. We deteriorate the current order of a simple society which bring about pandemonium to their physiology, behavior and culture. One study shows that the indigenous people of Australia, Maori, are now suffering from high risk of lung cancer. Doctors assumed that almost all cases of lung cancer in Maori are due to smoking; this is unlikely to be the case because long before, it is not in the culture of the Maori to smoke. Smoking only penetrated the culture of Maori when they forced to undergo European settlement. Environmental tobacco smoke (passive smoking), smoking marijuana, occupational exposures, diet, socioeconomic status, or level of deprivation are also likely to play a role in the pathogenesis of lung cancer in Maori. (Journal of the New Zealand Medical Association) Another case reported, according to the article “The Price of Progress” is the aggravated case of vitamin A deficiency in Brazilians which caused permanent blindness. Many specialists speculate, the deficiency was worsen by a milk distribution program. However, who will be jailed by only giving milk to the people they think needs it? None; who would even believe that they would lose their sight only by drinking milk? Health......

Process II How cigarette smoking affects the lungs Smoking has a detrimental effect on various organs on the body, but none are more directly affected than the lungs. After all, this is where all the smoke goes in soon after you take a puff. If you’ve been wondering how cigarette smoke can affect your lungs. The smoke that you inhale travels through your windpipe (trachea), down the bronchiole tubes, and into the air sacks (alveoli) within the lungs. This is where the regeneration of oxygen within our system takes place. The effects of smoking work in disturbing the balance that is maintained within the lungs; tar starts to deposit on the bronchiole tubes, and nicotine works in constricting the blood vessels. The lungs do work in trying to get rid of this toxic build up by pushing up tar and other constituents up the bronchiole pipe, and this travels further up the trachea. This is what comes out in the form of phlegm. However, not all the build up manages to come out in this manner. Since the nicotine works in paralysing the cilia within the lungs, the lungs find it harder to expel the tar. While the cilium does get better after an all night’s absence of cigarette smoke, habitual smoking can cause permanent damage to the cilia. Chemicals such as hydrogen cyanide that are found in......

These systems are known as the Integumentary system includes the skin, hair, nails, sebaceous and sweat glands. The Skeletal system includes the bones, cartilage, ligaments, and other stabilizing connective tissue structures. Muscular system includes skeletal muscles, connective tissue such as fascia and tendons, and proprioceptors. Nervous and Endocrine systems work together to coordinate organ system functions and respond to environmental stimuli. The nervous system controls relatively swift responses, like those related to movement, while the endocrine system regulates slower responses such as metabolic rate. The Cardiovascular system includes the heart, blood vessels, arteries, veins, and blood. The Lymphatic system is a network of lymphatic vessels, fluid called lymph, and lymph nodes that contain a large number of lymphocytes. The lymphatic systems functions are to return fluids from the body tissues to the blood; transport hormones, nutrients, and waste products from tissues into circulation; and defend the body from infection and disease via white blood cells or lymphocytes.

Asbestos, Health

...window glass and computer chips). These substances form fibers with varying shapes and sizes and are found throughout the earth. There are three commonly available types of asbestos; chrysotile (white asbestos) comes mainly from Canada, and has been very widely used in the US, amosite (brown asbestos) comes from southern Africa, and crocidolite (blue asbestos) comes from southern Africa or Australia. All three have been associated with cancerous and non-cancerous lung disease. Asbestos has been used often in a variety of building materials for insulation and as a fire retardant. Asbestos is usually found in older homes in pipes, furnaces, roof shingles, millboard, textured paints, coating materials, and floor tiles. However, the presences of asbestos containing products in the area in which you live, work, or go to school at is not necessarily a hazardous condition. It is only hazardous when asbestos containing products break down and become airborne then a hazardous condition is created. The clinical symptoms usually include pain in chest or abdomen, coughing up blood, difficulty swallowing, bone pain or tenderness, weight loss, slowly progressing shortness of breath and cough, often 20 to 40 years after exposure to asbestos(Medicine net). Currently about 125 million people in the world are exposed to asbestos at the workplace.
