  • Buckley Jr - 2,713 words
    1. WM. F. BUCKLEY JR. Last summer WFB was asked by the New York Bar Association to make a statement to the panel of lawyers considering the drug question. He made the following statement: We are speaking of a plague that consumes an estimated $75 billion per year of public money, exacts an estimated $70 billion a year from consumers, is responsible for nearly 50 per cent of the million Americans who are today in jail, occupies an estimated 50 per cent of the trial time of our judiciary, and takes the time of 400,000 policemen--yet a plague for which no cure is at hand, nor in prospect. Perhaps you, ladies and gentlemen of the Bar, will understand it if I chronicle my own itinerary on the sub ...

  • Acid Rain - 1,289 words
    Acid Rain Pollution comes in various forms. Whether its toxic waste, CFCs, or sewage, they are all hazardous, to the earth. These can deplete the earth and its inhabitants of resources, causing a harmful change. A product of pollution is acid rain. We shall see that acidification is harmful to all forms of life. Acid rain is any form of precipitation that is polluted by sulphur dioxide (SO2), and nitrogen oxides (NOX). This acid precipitation can be in the form of rain, snow, sleet, fog, or cloud vapors. The acidity of substances dissolved in water are measured by their pH levels. Normal precipitation pH levels fall between 5.0-5.6.2 When levels fall below these numbers, then the precipitati ...

    ... . These particles collect on the leaves of the tree, and studies have shown that when these particles contain acid they can cause damage to the leaves. The leaves are the part of the tree that help make food, hence any damage to the leaves will result in harm to the health of the entire tree. Coniferous trees are vulnerable to the harmful effects of acid rain as well. The tree's needles are designed to nourish the tree after they fall to the ground. Each needle houses whole colonies of microscopic bacteria and algae that help the tree change nitrogen into food at the roots. Acid rain will often burn away this material, thereby reducing adequate food supply, and weakening the tree's healt ...

  • Air Pollution - 1,546 words
    Air Pollution Air Pollution is addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life. Pollution is changing the earth's atmosph ...

Ozone depletion is looked upon as a problem that up till now, we can not fix. Air pollution has caused this hole in the ozone layer. The ozone layer absorbs 99% of the sun's harmful energy. It prevents ultraviolet radiation from reaching the Earth's surface and the troposphere. It protects humans from sunburn, skin and eye cancer, and cataracts. It also prevents much of the oxygen in the troposphere from being converted to ozone (gas). In the mid-seventies chemists F. Sherwood Rowland and Mario J. Malian discovered CFC's were creating a global chemical time bomb by ...

  • Alternative Medicine - 1,013 words
    Alternative Medicine Alternative Medicine by Joe Grodjesk Sociology Of Medicine Professor Buban May 5, 2001 Alternative Medicine Throughout recorded history, people of various cultures have relied on what Western medical practitioners today call alternative medicine. The term alternative medicine covers a broad range of healing philosophies, approaches, and therapies. It generally describes those treatments and health care practices that are outside mainstream Western health care. People use these treatments and therapies in a variety of ways. Alternative therapies used alone are often referred to as alternative; when used in combination with other alternative therapies, or in addition to co ...

  • Animal Cruelty - 1,051 words
    Animal Cruelty Jeff Albrecht Joseph Aimone Writing and Rhetoric 13 December 2000 Animal Cruelty One of the most touchy aspects of our relationship with animals is the use of animals in laboratory sciences. Some manufactures of cosmetics and household products still conduct painful and useless tests on live animals, even though no law requires them not to. Some people, called anti-vivisectionists, are at one extreme in their concern. They want an abolition of all experiments on live animals. At the other extreme there are those who say that it is quite all right for us to do whatever we like to animals. They say that God gave us such a right, since it is written in the bible (Genesis 1:26) th ...

  • Animal Rights - 488 words
    Animal Rights Animal Rights As Doctor Zola-Morgan stated in a speech to animal right activists, I've seen the impact of the animal rights movement. I believe this is an attack on science of the worst kind. If we allow it to prevail it will take us back to the dark ages. Too much of the public has come to think of medical researchers as tormenters rather than healers. The good is overlooked and the bad is exploited. Although many people think that animal research is morally wrong, animal research should continue because it is critical to continued progress in human health and alternatives to research animals are not available. Animal rights activists feel that animal research is immoral. They ...

  • Animal Rights Vs Human Rights - 1,858 words
    Animal Rights Vs. Human Rights h Laboratory animals The use of laboratory animals is important to three main areas: biomedical research, product safety testing, and education. Biomedical researchers use animals to extend their understanding of the workings of the body and the processes of disease and health, and to develop new vaccines and treatments for various diseases. The research these people do isnt only for human benefit; it is also helping to develop veterinary techniques. The industry uses animals to test the effectiveness and safety of many consumer products, such as cosmetics, household cleaning products, pesticides, chemicals, and drugs. Educators, from elementary school all the ...

  • Animal Testing - 953 words
    Animal Testing For centuries, animals have been used in medical research. Since 1875, animal experimentation has been an on going heated debate on whether experiments on animals are ethical. At the very start, the movement against animal testing focused mainly on the "inhumanity of hurting and killing living beings for experimental discovery" (Achor 95). However, in these few decades, scientific invalidity was one of the focusing claims to object to vivisection, which is an "injurious use of animals in laboratories and classrooms, whether for experimentation, product testing, training, or demonstration" (Achor 94-95). Animals are innocent and they are not able to fight back for any means of ...

  • Animal Testing - 972 words
    Animal Testing Traditionally, animals have been used to ensure the safety of our consumer products and drugs. Yet around the world, scientists, regulators and animal protectionists work together to develop alternatives to their use. The use of animals in the life sciences dates back to ancient Greece and the earliest medical experiments. To learn about swallowing, physicians cut open into the throat of a living pig. To study the beating heart, they cut open into its chest. For centuries physicians and researchers used animals to enhance their knowledge about how the various organs and systems of the body functioned, as well as to hone their surgical skills. As long as animals have been used ...

  • Automobile Emissions - 1,899 words
    Automobile Emissions Pollution from automobile emissions has become over the past few decades an issue of great concern. With a growing number of motor vehicles on our roads great concern has been attributed to the effects of these emissions to our health and to the environment. Several of the gases emitted, which when present in certain concentrations in our atmosphere can be toxic, therefor these ultimate concentrations must never be achieved. Strict legislation as well as sophisticated control technology has been implemented in the automotive industry in order to limit the pollution caused. These aspects of automotive pollution shall be further discussed in this paper. KEYWORDS: Pollution ...

  • Clean Air Act - 1,133 words
    Clean Air Act 1990, the federal Clean Air Act was passed to improve air quality in the United States. President Bush's proposed amendments to the Clean Air Act initially would have led to the introduction of alternative, non-petroleum fuels. The petroleum and oxygenate industries responded by offering a reformulated gasoline program as a substitute for most of the alternate fuel proposals. As a result, the amendments to the federal Clean Air Act adopted in 1990 required steps to achieve lower vehicle emissions, including programs to oxygenate and reformulate gasoline. Oxygenated gasoline is designed to increase the combustion efficiency of gasoline, thereby reducing carbon monoxide emissions ...

  • During The 1970s, Health Concerns About The Herbicides Brought About Government Restrictions That Caused A Sharp Decrease In - 1,180 words
    During the 1970s, health concerns about the herbicides brought about government restrictions that caused a sharp decrease in the manufacture and use of 2,4,5-T. Since 1983, the use of 2,4,5-T has been prohibited in the United States. Many other countries also have ended its use. Of additional concern is a contaminant called dioxin (2,3,7,8,-tetrachlorodibenzo-p-dioxin, or TCDD), which often forms when 2,4,5-t is manufactured. Of the approximately 75 chemicals in the dioxin family, TCDD is the most toxic. It can cause chlorance, a skin disease, and is suspected to cause some kinds of cancer. The TCDD level in agent orange varied from 0.02 to 54 micrograms per gram of 2,4,5-T. (Cancer 1996) Ag ...
