How Pollution Destroys the Atmosphere and Habitats Essay Introduction â€Å"Nowadays, industries, automobiles, power stations, etc. have become indispensable in our daily life.† ( Science Level K page 242) Have you ever wondered what causes pollution? Forms of Pollution Pollution is the process whereby various harmful substances are added to the environment (land, water, air etc.) by human and natural activities. The main various types of pollution that exist are: Air Pollution Air pollution is the cause of release of chemicals, and particulates into the atmosphere which endanger human life and living matter on the earth by humans, human products and natural disasters. As the current era of modern industrialization progresses more and more waste of the results of their production become toxins which can be freely inhaled and fatal to mammals. Water Pollution Water pollution is the introduction of chemical, biological and physical matter into large bodies of water that corrupt the quality of life that lives in it and consumes it. Like the discharging of waste water from commercial and industrial waste (intentionally or through spills) into surface waters; oil spills, household chemicals, pesticides and fertilizers are the major sources of water pollution. Land Pollution Land pollution is pollution of the Earth’s natural land surface by industrial, commercial, domestic and agricultural activities. It occurs when chemicals are released intentionally, by spill or underground leakage. Some of the main contributions to land pollution are deforestation, construction debris, industrial factories etc. Effects on Environment Human Health Pollution has many different forms that are not only doing damage to our environment but also to our health. Pollutants can enter human body causing diseases. Air pollution can cause breathing problems and eye, throat and skin irritation. When solid waste is not properly treated and disposed of, it can become a breeding for pests and disease can spread. Water pollution can cause waterborne diseases by polluted drinking water, polluted beach water, and, serious diseases by water polluted by chemicals. Water pollution may also result from interactions between water and contaminated soil, as well as from deposition of air contaminants (such as acid rain).Damage to people may be caused by fish foods coming from polluted water and vegetable crops grown or washed with polluted water. Plants Leaves find it difficult to produce food in polluted air. When trees begin to lose their leaves, they may eventually die. When there is too much chemical content in the water absorbed by the roots, it can also affect plant life. Water Pollution that affects plants would include acid rain. Soil Pollution problems affecting plants include the overuse of pesticides which selects for resistant strains of insects and weeds, the loss of topsoil due to overdevelopment and soil erosion, and the uptake of toxic chemicals through the mismanagement of solid waste. Acid rain can kill trees, destroy the leaves of plants, can infiltrate soil by making it unsuitable for purposes of nutrition and habitation. Trees and plants may absorb soil contaminants and pass them up the food chain. Animals Oil spills in the seas and oceans result in birds and animals (e.g. penguins and seals) being coated in oil. This makes it difficult for them to float and keep warm and they may eventually die. Solid waste in the water encourages the growth of algae which depletes water of oxygen and kills marine life. People, who don’t throw away their trash, throw it on the ground. It is very sad for stray cats and dogs who wander the streets with nothing to eat but garbage. That is how pollution is very effective on animals and how they used to live. Pollution Originates in Nature Volcanic eruptions, sandstorms and natural forest fires are one of the natural activities that cause pollution. These events cause a large amount of substances such as ash and dust, which are harmful to our health, to be added to the environment. The volcanic gases that pose the greatest potential hazard to people, animals, agriculture, and property are sulfur dioxide, carbon dioxide which also can be generated by forest fires, and hydrogen fluoride. Sulfur dioxide gas can lead to acid rain and air pollution downwind from a volcano. Globally, large volcano explosive eruptions that inject a tremendous volume of sulfur aerosols into the stratosphere can lead to lower surface temperatures and promote depletion of the Earths ozone layer. Because carbon dioxide gas is heavier than air, the gas may flow into in low-lying areas and collect in the soil. The concentration of carbon dioxide gas in these areas can be lethal to people, animals, and vegetation. A few historic eruptions have released sufficient fluorine-compounds to deform or kill animals that grazed on vegetation coated with volcanic ash; fluorine compounds tend to become concentrated on fine-grained ash particles, which can be ingested by animals. Ways to Prevent Pollution Most human activities produce some waste products, but it is important to make sure that we have as little pollution as possible. Many people are switching to clean technology. That means having the same benefits from our modern life-style without the pollution. Electric cars, environmentally sensitive washing powders and solar-powered energy are examples. Less pollution is not only good for wildlife and nature human health benefits from less pollution as well. That means lower medical bills, and a better quality of life. There are many ways to stop pollution like:- * The best way to prevent water pollution is to not throw trash and other harmful chemicals into our water supplies because it causes harm to the rivers and lakes. * Throw trash in the proper places. * Reduce, reuse, and recycle things in your house. * Because of water run-off, dont put oils down the storm drain. * Cut the plastic ties on sodas so they dont hurt animals in case the ties in up in the bay. Conclusion We should all work to reduce pollution to work towards a greener and safer earth; for the next generation. Let’s give people hope for a better future; and let’s erase the thought of the â€Å"2012† ending, all over the world.

When General Rochambeau met General Washington in 1781 to determine their next move against the British, Washington wanted to attack New York City. Rochambeau convinced him that the wiser move was to move South. Word had come from General Lafayette in Virginia that Cornwallis had taken up a defensive position at Yorktown. Cornwallis was situated next to the York River. If they could surround the city by land and cut off Cornwallis' escape route on the river, Washington and Rochambeau would strike an enormous blow to the British forces. Planning for the elaborate campaign began immediately. French Admiral de Grasse, stationed in the West Indies, would sail with his fleet to the Chesapeake Bay and secure the mouth of the York River. Meanwhile, Washington and Rochambeau would march south to Yorktown and form a semicircle around the city. The plan was simple in concept, but it would take great military skill to execute. First, Washington and Rochambeau started to march towards New York City. They stationed approximately 2500 men at the American forts near the city to fool the British into believing that Washington's entire force was still there. Then the combined Franco-American army raced south to Virginia. As they marched south, Admiral de Grasse's fleet arrived at the Chesapeake Bay. They defeated the British fleet of Admiral Thomas Graves and won control of the entire bay. More importantly, this meant that they controlled the mouth of the York River and could prevent both Cornwallis' escape and any British communication with Cornwallis. On September 28, 1781, Washington and Rochambeau, along with Lafayette's troops and 3,000 of de Grasse's men, arrived at Yorktown. In all, there were approximately 17,000 men converging on Cornwallis' camp. The stage was set for the final showdown in America's fight for independence. The combined forces approached Yorktown from the South. The French, under Rochambeau, formed the left flank of the attack, while the American troops, under Washington and Lafayette, approached from the right. The city was soon surrounded and under heavy fire. On October 14, the Franco-American forces captured 2 major British redoubts. Cornwallis' options were running out. He even tried sending blacks infected with smallpox over enemy lines in an attempt to infect the American and French troops. After a futile counterattack, Cornwallis offered to surrender on October 17. On the 19th of October, the papers were signed and he officially surrendered. jane eyre :: essays research papers When General Rochambeau met General Washington in 1781 to determine their next move against the British, Washington wanted to attack New York City.

Moral absolutism Essay

The choices we make in our everyday life all have to do with our ethics. In this paper the topic will discuss the similarities and differences between virtue theory, utilitarianism, and deontological ethics. In order to understand the similarities, and differences of virtue theory, utilitarianism, and deontological ethics we must first define them. Virtue theory is defined as a moral excellence. It is a positive trait quality demand to be morally good and is valued as a foundation of principle and good moral being. It takes the viewpoint that in living your life you should try to cultivate excellence in all that you do and all that others do. Utilitarianism is a theory that suggests that an action is morally right when that action produces more utility for the group than any other alternative. We need to understand what our consequence would be based on our choice. When we make the right choice we will get a positive consequence and are acting morally; if we make the wrong choice the consequences will be acting immorally. Deontological moral is focused on loyalty to independent moral rules or duties. To make the right choices we need to comprehend what our duties are and the rules of our moral perspective. This is a matter of what we view to be moral or immorally based on our beliefs. The similarities between the three theories represent the good in people and how they strive for excellence. The differences are with virtue theory describes a person’s character, cultivating excellence in all we do. Utilitarianism addresses ethical and morality issues by addressing the balance of good over bad consequences. The morality associated with this theory suggests actions that produce a total utility for the group. Deontological ethics have a definition of a definition of a person’s dedication to recognize moral duties. In my current position as an assistant manager I am often put in a situation that includes some type of confidentiality with an associate that falls under me. If I am told about a certain situation that an associate is having in their personal life I have been told in trust and this be unethical for me to tell everyone else what is going on. Also when I have to write up any associate for work performance, that should be kept between me and that associate. For me to be able to keep my word about a particular situation involving any of my associates consist of moral concepts. Values, virtues, and ethics distinguish those actions as being morally right or morally wrong.

Around the world there are numerous types of addictions that every type of person suffers from, but there is only one type of addiction that I am interested in discussing today, alcoholism. I am sure that even if your life is not directly affected by the disease, you are at least a little familiar with the basics. In this paper I plan to give you a brief understanding of the three basic issues you should be informed upon so you can make better decisions involving alcohol in the future. First, I will discuss who is at the most risk of falling victim to alcoholism, second, I will discuss the symptoms of alcoholism, and finally I will discuss the impact alcoholism has on family, children, and the individuals suffering from alcoholism. To begin, there are all types of people from every walk of life that become victims of alcoholism. But you may be asking yourself who is at the most risk of developing an addiction to alcohol? Well, the answer to that question depends on several variables like, genetics; high stress, anxiety, or emotional pain; close friends or partners who drink excessively; and sociocultural factors that glorify alcohol (Kail Cavanaugh 341). Taking these factors into account, when it comes to gender, more men than women develop alcoholism (Kail Cavanaugh 341).
