    Animal Testing
    Please Read This Warning Before You Use This Essay for Anything (It Might
    Save Your Life) Animal Testing Using animals for testing is wrong and should be
    banned. They have rights just as we do. Twenty-four hours a day humans are using
    defenseless animals for cruel and most often useless tests. The animals have no
    way of fighting back. This is why there should be new laws to protect them.
    These legislations also need to be enforced more regularly. Too many criminals
    get away with murder. Although most labs are run by private companies, often
    experiments are conducted by public organizations. The US government, Army and
    Air force in particular, has designed and carried out many animal experiments.
    The purposed experiments were engineered so that many animals would suffer and
    die without any certainty that this suffering and death would save a single
    life, or benefit humans in anyway at all; but the same can be said for tens of
    thousands of other experiments performed in the US each year. Limiting it to
    just experiments done on beagles, the following might sock most people: For
    instance, at the Lovelace Foundation, Albuquerque, New Mexico, experimenters
    forced sixty-four beagles to inhale radioactive Strontium 90 as part of a larger
    ^Fission Product Inhalation Program^ which began in 1961 and has been paid for
    by the US Atomic Energy Commission. In this experiment Twenty-five of the dogs
    eventually died. One of the deaths occurred during an epileptic seizure; another
    from a brain hemorrhage. Other dogs, before death, became feverish and anemic,
    lost their appetites, and had hemorrhages. The experimenters in their published
    report, compared their results with that of other experiments conducted at the
    University of Utah and the Argonne National Laboratory in which beagles were
    injected with Strontium 90. They concluded that the dose needed to produce
    ^early death^ in fifty percent of the sample group differed from test to test
    because the dogs injected with Strontium 90 retain more of the radioactive
    substance than dogs forced to inhale it. Also, at the University of Rochester
    School Of Medicine a group of experimenters put fifty beagles in wooden boxes
    and irradiated them with different levels of radiation by x-rays. Twenty-one of
    the dogs died within the first two weeks. The experimenters determined the dose
    at which fifty percent of the animals will die with ninety-five percent
    confidence. The irritated dogs vomited, had diarrhea, and lost their appetites.
    Later, they hemorrhaged from the mouth, nose, and eyes. In their report, the
    experimenters compared their experiment to others of the same nature that each
    used around seven hundred dogs. The experimenters said that the injuries
    produced in their own experiment were ^Typical of those described for the dog^
    (Singer 30). Similarly, experimenters for the US Food and Drug Administration
    gave thirty beagles and thirty pigs large amounts of Methoxychlor (a pesticide)
    in their food, seven days a week for six months, ^In order to insure tissue
    damage^ (30). Within eight weeks, eleven dogs exhibited signs of ^abnormal
    behavior^ including nervousness, salivation, muscle spasms, and convolutions.
    Dogs in convultions breathed as rapidly as two hundred times a minute before
    they passed out from lack of oxygen. Upon recovery from an episode of
    convulsions and collapse, the dogs were uncoordinated, apparently blind, and any
    stimulus such as dropping a feeding pan, squirting water, or touching the
    animals initiated another convulsion. After further experimentation on an
    additional twenty beagles, the experimenters concluded that massive daily doses
    of Methoxychlor produce different effects in dogs from those produced in pigs.
    These three examples should be enough to show that the Air force beagle
    experiments were in no way exceptional. Note that all of these experiments,
    according to the experimenters^ own reports, obviously caused the animals to
    suffer considerably before dying. No steps were taken to prevent this suffering,
    even when it was clear that the radiation or poison had made the animals
    extremely sick. Also, these experiments are parts of series of similar
    experiments, repeated with only minor variations, that are being carried out all
    over the country. These experiments Do Not save human lives or improve them in
    any way. It was already known that Strontium 90 is unhealthy before the beagles
    died; and the experimenters who poisoned dogs and pigs with Methoxychlor knew
    beforehand that the large amounts they were feeding the animals (amounts no
    human could ever consume) would cause damage. In any case, as the differing
    results they obtained on pigs and dogs make it clear, it is not possible to
    reach any firm conclusion about the effects of a substance on humans from tests
    on other species. The practice of experimenting on non-human animals as it
    exists today throughout the world reveals the brutal consequences of speciesism
    (Singer 29). In this country everyone is supposed to be equal, but apparently
    some people just don^t have to obey the law. That is, in New York and some other
    states, licensed laboratories are immune from ordinary anticruelty laws, and
    these places are often owned by state universities, city hospitals, or even The
    United States Public Health Service. It seems suspicious that some government
    run facilities could be ^immune^ from their own laws (Morse 19). In relation,
    ^No law requires that cosmetics or household products be tested on animals.
    Nevertheless, by six^o clock this evening, hundreds of animals will have their
    eyes, skin, or gastrointestinal systems unnecessarily burned or destroyed. Many
    animals will suffer and die this year to produce ^new^ versions of deodorant,
    hair spray, lipstick, nail polish, and lots of other products^ (Sequoia 27).
    Some of the largest cosmetics companies use animals to test their products.
    These are just a couple of the horrifying tests they use, namely, the Drazie
    Test. The Drazie test is performed almost exclusively on albino rabbits. They
    are preferred because they are docile, cheap, and their eyes do not shed tears
    (so chemicals placed in them do not wash out). They are also the test subject of
    choice because their eyes are clear, making it easier to observe destruction of
    eye tissue; their corneal membranes are extremely susceptible to injury. During
    each test the rabbits are immobilized (usually in a ^stock^, with only their
    heads protruding) and a solid or liquid is placed in the lower lid of one eye of
    each rabbit. These substances can range from mascara to aftershave to oven
    cleaner. The rabbits^ eyes remain clipped open. Anesthesia is almost never
    administered. After that, the rabbits are examined at intervals of one,
    twenty-four, forty-eight, seventy-two, and one hundred an sixty-eight hours.
    Reactions, which may range from severe inflammation, to clouding of the cornea,
    to ulceration and rupture of the eyeball, are recorded by technicians. Some
    studies continue for a period of weeks. No other attempt is made to treat the
    rabbits or to seek any antidotes. The rabbits who survive the Drazie test may
    then be used as subjects for skin-inflammation tests (27). Another widely used
    procedure is the LD-50. This is the abbreviation of the Lethal Dose 50 test.
    LD-50 is the lethal dose of something that will kill fifty percent of all
    animals in a group of forty to two hundred. Most commonly, animals are
    force-feed substances (which may be toothpaste, shaving cream, drain cleaner,
    pesticides, or anything else they want to test) through a stomach tube and
    observed for two weeks or until death. Non-oral methods of administering the
    test include injection, forced inhalation, or application to animals skin.
    Symptoms routinely include tremors, convultions, vomiting, diarrhea, paralysis,
    or bleeding from the eyes, nose, mouth. Animals that survive are destroyed (29).
    Additionally, when one laboratory^s research on animals establishes something
    significant, scores of other labs repeat the experiment, and more thousands of
    animals are needlessly tortured and killed (Morse 8). Few labs buy their animal
    test subjects from legitimate pet stores and the majority use illegal pet
    dealers. There are many stolen animal dealers that house the animals before,
    during , and after testing. These ^farms^ most frequently hold animals between
    tests while the animals recuperate, before facing another research ordeal. These
    so called farms in question are mainly old barn-like buildings used as hospitals
    and convalescent (recovery) wards are filthy, overcrowded pens. At one farm in
    particular dogs with open chest wounds and badly infected incisions, so weak
    that many could not stand, were the order of the day. These dogs were
    ^recuperating^ from open-heart and kidney surgery. Secondly, a litter of
    two-day-old pups were found in a basket, with no food provisions in sight (Morse
    19). In every pen there were dogs suffering from highly contagious diseases. An
    animal^s road to a lab is seldom a direct one. Whether he^s stolen picked up as
    a stray, or purchased, there^s a de tour first to the animal dealer^s farm;
    There he waits- never under satisfactory conditions- until his ride, and often
    life, comes to an end at the laboratory (23). Every day of the year, hundreds of
    thousands of fully conscious animals are scalded, or beaten, or crushed to
    death, and more are subjected to exotic surgery and then allowed to die slowly
    and in agony. There is no reason for this suffering to continue (Morse 8). In
    conclusion, animal testing is inhumane and no animal should be forced to endure
    such torture. Waste in government is one thing; it seems to be an accepted
    liability of democracy. But the wasting of lives is something else. How did it
    ever get this way?
