Modern Health Hazards
Modern Health Hazards, dangers arising from man made circumstances that threaten the wellbeing of humans environment. These are normally taken as hazards arising from the mistakes human's have made over the past year's affecting the Healthy status of the entire planet completely. Different hazards threat human life on earth & By the level or extent of threat the effect can be serious and sometimes even cause death. Modern Hazards mainly are pollution of different types ,Drugs , chemical usage and some day to day human activities too Air Pollution, contamination of the atmosphere by gaseous, liquid, or solid wastes or by-products that can endanger human health and the health and welfare of plants and animals, or can attack materials, reduce visibility, or produce undesirable odours. Among air pollutants emitted by natural sources, only the radioactive gas radon is recognized as a major health threat. A by-product of the radioactive decay of uranium minerals in certain kinds of rock, radon seeps into the basements of homes built on these rocks, posing a risk of lung cancer to residents.
Effects of Air Pollution
Potential pollutants may exist in the materials entering a chemical or combustion process (such as lead in petrol), or they may be produced as a result of the process itself. Carbon monoxide if inhaled in excess can cause lung problems, loss of oxygen in the blood & finally cause death .In December 1984 deadly methyl isocyanate gas was leaked from a chemical plant in Bhopal, causing the deaths of at least 3,300 people.
Water Pollution, contamination of water by foreign matter such as micro-organisms, chemicals, industrial or other wastes, or sewage. Such matter deteriorates the quality of the water and renders it unfit for its intended uses.
Effects of Water Pollution
Notable effects of water pollution include those involved in human health. Nitrates (the salts of nitric acid) in drinking water can cause a disease in infants that sometimes results in death. Cadmium in sludge-derived fertilizer can be absorbed by crops; if ingested in sufficient amounts, the metal can cause an acute diarrhoeal disorder and liver and kidney damage. The hazardous nature of inorganic substances such as mercury, arsenic, and lead has long been known or strongly suspected.
Noise Pollution, adverse effects of noise in our living and working environment. Noise is, by definition, unwanted sound. It may be annoying, it may interfere with speech communication, leisure, or relaxation, and, at very high levels which may occur at work or during certain noisy leisure activities, it may result in hearing loss by causing damage to the hair-cells in the cochlea in the inner ear.
The novel Jane Eyre, written by Charlotte Bronte, is about Jane who is a strong, independent women who went from being an orphaned, isolated ten-year-old to excelling at school and becoming a governess.The character Blanche Ingram is intended to marry Edward Rochester, the man Jane loves. Throughout the first half of the novel Bronte uses Blanche Ingram as a foil to Jane, to reveal her true persona. This is evident firstly by appearance, where Blanche is described as beautiful and Jane plain, their different inner characters, the way they connect with Adele and finally how they express their feelings towards Edward Rochester.
Today pollution is very high in both inland and marine waters. All different types of water pollution are contributing factors in this problem. Here are some things that are associated with pollution: Pathogens: Pathogens are disease causing bacteria, viruses, and protozoa. They usually come from human sewage. As pathogen numbers increase, so does the risk of human health.
There are six common pollutants in the air, which include ozone, particulate matter, carbon monoxide, nitrogen oxide, sulfur dioxide, and lead. These pollutants led to many different symptoms across the United States. Ozone pollution leads to impaired respiratory system. Particulate matter affects respiratory systems, causes cancer, and premature death. Carbon monoxide affects the bloodstream and reduces oxygen to the body’s organs. Nitrogen oxide causes influenza. Sulfur dioxide effects respiratory illness and pulmonary defenses. Lead causes effects in the liver,
Residents living closest to manufacturing plants and factories reap the most adverse health affect, however, hazardous air pollutants effect the ozone layer which effects everyone.
'Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives(in) it. ' (Azeem 1). In Canada, most people live in the southern part along with many agricultural and industrial activities causing the worst cases of water pollution. Water pollution is caused by population growth and industrialization, but can be prevented if proper controls are taken into consideration to help reduce the discharge of waste materials. Water pollution has been a huge disadvantaging concern for humans as well as wildlife for over many decades, but can actually be prevented if attempted. Preventing waste materials from being dumped into lakes and rivers, controlling
Ursula Le Guin’s A Wizard of Earthsea shares a lot of themes with Lao Tzu, the legendary philosopher’s Tao Te Ching. A Wizard of Earthsea has a constant theme of controlling power and of not ruining the balance. The more power a person has, the more responsibility he or she bestows. The book also focuses on the need of one to be farsighted, and to seek consequences. Ged represents an average young man of today, who seeks power, and doesn’t realize that every one of his actions has consequence. In Tao Te Ching, Lao Tzu constantly talks about doing by not doing. This does not mean literally not doing anything, but it means not doing those things that don’t follow the way of nature, which is simil...
This saga is an exquisite account of a life-long reverence for a women who Jim has known as a friend and companion since his childhood when he, an orphaned boy from Virginia, and she, a fourteen year old immigrant from Bohemia, travelled to the unsettled, unbroken plains of Nebraska at the turn of the century. The reader follows the mesmerizing tale of immigrant origins, hardships, as Jim celebrates the strength and the beauty of a heroine, Ántonia Shmirida, whose strength to overcome, has won both his love and soul. While Jim lives on his grandparent’s already successful farm, the immigrant family is forced to reside in a grass house carved into the side of a hill. The Bohemian immigrants struggle against nature to learn how to farm, to survive the hardship presented in this foreign, unaccepting land. Although her name is in the title, it is not truly her story. The preposition “my” in the title carries possession, so Jim’s story is his version. The subsequent story is his account, his perspective, of his first
In Jane Eyre, Charlotte Bronte uses various characters to represent aspects of reason and passion, thereby establishing a tension between the two. In fact, it could be argued that these various characters are really aspects of her central character, Jane. From this it could be argued that the tension between these two aspects really takes place only within her mind. Bronte is able to enact this tension through her characters and thus show dramatically the journey of a woman striving for balance within her character. As a prerequisite for marriage, Jane uses this determination in her relationships with Mr. Rochester and St. John.
In O’Connor’s short story, “The Misfit”, a grandmother, her son, and his wife and children go on a family field trip. There is a criminal on the loose but the family decides to proceed with their plans anyway. The criminal is called the Misfit, and as with the rest of the story, this is full of irony. The thwarted family road trip might symbolize the choices a person makes and the consequences they bring.
There are many kinds of air pollution. The ones I want to talk about are the ozone, acid rain, carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore, ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease, loss of pulmonary elasticity, and premature aging of our lungs. Next, is acid rain, which occurs in the atmosphere in the form of sulfur and nitrogen oxide. These pollutants can have serious damaging affects on aquatic, forest and wildlife ecosystems, as well as deterioration of buildings. Carbon monoxide is another form of pollution. It reduces the blood?s ability to carry oxygen. If a human is exposed to higher levels, it can cause chest pains, angina attacks or even death.
Sigmund Freud was born on May 6, 1856, in Freiberg, Moravia, a small town in Austro-Hungarian. His parents were Amalia and Jacob Freud. His father was an industrious wool merchant with a happy and witty personality. His mother was a cheerful and vivacious woman. He was one of nine siblings. He was the first-born child of Amali and Jacob; however, two male siblings where from his father’s first marriage. When he was a young boy, his family moved to Vienna where he lived most of his life. At the age of twenty-six, he fell madly in love with Martha Bernays when she was visiting one of his sisters. Shortly thereafter, they married and had six children of their own three boys and three girls. His children describe him as a loving and compassionate man.
Out of the female characters that are presented in Bronte's novel most serve a purpose in developing or contributing to Jane's character. Through these five women the evidence is obvious the Bronte used the other characters as models for Jane. Some possess qualities that Jane needed to avoid, some that she needed to learn. Some of the women were exaggerations of personality traits that Jane already possessed but were able to show the reader the outcome of such exceeding qualities.
Technological and accidental hazards can be occur without warning and can be both hazardous material incidents and failures at nuclear power plant. In some cases, victims that have been exposed to harmful chemicals or radiation show little to no symptoms until several years later. There are an increasing number of new substances and chemicals being manufactured which has increased the likelihood of a hazardous material spill or release. This also increases the risk to the environment and to the health and safety of a community.
Water pollution is one of the main concerns of the environment. It is known as a change in the chemical or physical condition of the waters. Polluting the waters is causing harmful and tragic diseases that affect many families. It is also a global problem that not only affects people but also animals and plants. Water pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
Water pollution is very harmful to the environment and living things. Water pollution can come from many different sources. If the pollution comes from only one source, such as an oil spill, it is called point-source pollution. If it comes from many different sources, it is called nonpoint-source pollution. Most water pollution affects the immediate area surrounding the source, but there are some types of pollution, such as hazardous, that can affect areas miles away from the source. Water pollution is something that can be prevented; it is important to be aware of the causes of water pollution to keep the environment safe and clean for the many generations to come.
