Hypnosis And Psychics Essay, Research Paper


Until the recent demise of the Soviet Union, we lived under the daily


threat of nuclear holocaust extinguishing human life and the entire


biosphere. Now it looks more likely that total destruction will be


averted, and that widespread, but not universally fatal, damage will


continue to occur from radiation accidents from power plants, aging


nuclear submarines, and perhaps the limited use of tactical nuclear


weapons by governments or terrorists.


What has gone largely unnoticed is the unprecedented lethal threat of


genetic engineering to life on the planet. It now seems likely, unless


a major shift in international policy occurs quickly, that the major


ecosystems that support the biosphere are going to be irreversibly


disrupted, and that genetically engineered viruses may very well lead


to the eventual demise of almost all-human life. In the course of the


major transformations that are on the way, human beings will be


transformed, both intentionally and unintentionally, in ways that will


make us something different than what we now consider human.


Regardless of the dangers, we are rushing full speed ahead on almost


all fronts. Some of the most powerful multinational chemical,


pharmaceutical and agricultural corporations have staked their


financial futures on genetic engineering. Enormous amounts of money are


already involved, and the United States government is currently


bullying the rest of the world into rapid acceptance of corporate


demands concerning genetic engineering research and marketing.


In the 1950’s, the media was full of information about the great new


scientific miracle that was going to make it possible to kill all of


the noxious insects in the world, to wipe out insect-born diseases and


feed the world’s starving masses. That was DDT. In the 1990’s, the


media is full of information about the coming wonders of genetic


engineering. Everywhere are claims that genetic engineering will feed


the starving, help eliminate disease, and so forth. The ideas and


evidence presented below are intended to help evaluate that central


question.


Some scientists believe that, since genetic codes determine the


appearance, personality, health, and aging process of human beings, if


that genetic information in the chromosomes could be decoded and the


genetic mechanism were understood, we could potentially control and


improve our health, quality of life, and the biochemical processes in


our bodies. In other words, we could control our own fate. Also, we’d


be able to improve the genes of other animals and vegetables so that


they could serve humankind better. At first sight, these ideas seem


reasonable and attractive. However, careful analysis reveals that they


are based upon an incorrect theory–the theory of gene determinism.


Genes are often described as ‘blueprints’ or ‘computer programs’ for


our bodies and all living organisms. Although it is true that genes are


specific sequences of DNA (deoxyribonucleic acid) that are central to


the production of proteins, contrary to popular belief and the now


outmoded standard genetic model, genes do not directly determine the


‘traits’ of an organism.1a They are a single factor among many. They


provide the ‘list of ingredients’ which is then organized by the


‘dynamical system’ of the organism. That ‘dynamical system’ determines


how the organism is going to develop. In other words, a single gene


does not, in most cases, exclusively determine either a single feature


of our bodies or a single aspect of our behavior. The genes are


processed through the self-organizing (’dynamical’) system of the


organism, so that the combination of a complex combination of genes is


subjected to a variety of environmental factors that lead to the final


results, whether somatic or ! behavioral.


^a gene is not an easily identifiable and tangible object. It is


not only the DNA sequence which determines its functions in the


organisms, but also its location in a specific chromosomal,


cellular, physiological and evolutionary context. It is therefore


difficult to predict the impact of genetic material transfer on the


functioning of the extremely tightly controlled, integrated and


balanced functioning of all the tens of thousands of structures and


processes that make up the body of any complex organism.


What has gone largely unnoticed is the unprecedented lethal threat of


genetic engineering to life on the planet. It now seems likely, unless


a major shift in international policy occurs quickly, that the major


ecosystems that support the biosphere are going to be irreversibly


disrupted, and that genetically engineered viruses may very well lead


to the eventual demise of almost all-human life. In the course of the


major transformations that are on the way, human beings will be


transformed, both intentionally and unintentionally, in ways that will


make us something different than what we now consider human.


Genetic engineering refers to the artificial modification of the


genetic code of a living organism. Genetic engineering changes the


fundamental physical nature of the organism, sometimes in ways that


would never occur in nature. Genes from one organism are inserted in


another organism, most often across natural species boundaries. Some of


the effects become known, but most do not. The effects of genetic


engineering, which we know, are usually short-term, specific and


physical. The effects we do not know are often long-term, general, and


also mental. Long-term effects may be either specific4 or general.


What harm could Genetic Engineering bring? The main potential harm of


Genetic Engineering is associated with artificial horizontal gene


transfer experimentation. Horizontal gene transfer occurs commonly in


nature. Genes can be exchanged between different bio-species. But the


frequency of these natural transfers is limited by the defense systems,


i.e. immune systems, of each bio-species. The immune system serves to


prevent invasion by harmful foreign genes, viruses, and so forth, so


that the bio-species can maintain its characteristic traits and normal


metabolism. The Genetic Engineering method of artificial horizontal


gene transfer works by penetrating or weakening the immune system and


using virule

nt genes as delivery vehicles. That is, the gene to be


transferred is combined with a virulent gene to effect penetration.


This method allows harmful virulent genes, especially those with


resistance to antibiotics, to become widespread in nature.


Genetically engineered material can enter the body through food or


bacteria or viruses. The dangers of lethal viruses containing


genetically engineered material and created by natural processes have


been mentioned above. The dangers of generating pathogens by vector


mobilization and recombination are real. Over a period of ten years, 6


scientists working with the genetic engineering of cancer-related on


co-genes at the Pasteur Institutes in France have contracted cancer.42


Non-human engineered genes can also be introduced into the body through


the use of genetically engineered vaccines and other medicines, and


through the use of animal parts genetically engineered with human genes


to combat rejection problems.


Gene therapy, for the correction of defective human genes that cause


certain genetic diseases, involves the intentional introduction of new


genes into the body in an attempt to modify the genetic structure of


the body. It is based on a simplistic and flawed model of gene function


which assumes a one-to-one correspondence between individual gene and


individual function. Since horizontal interaction43 among genes has


been demonstrated, introduction of a new gene can have unforeseen


effects. Another problem, already mentioned, is the slippery slope that


leads to the notion of designer genes. We are already on that slope


with the experimental administration of genetically engineered growth


hormone to healthy children, simply because they are shorter than


average and their parents would like them to be taller.44


A few years ago a biotech corporation applied to the European Patent


Office for a patent on a so-called “pharm-woman”, the idea being to


genetically engineer human females so that their breast-milk would


contain specialized pharmaceuticals. Work is also on going to use


genetic engineering to grow human breasts in the laboratory. It doesn’t


take much imagination to realize that not only would they be used for


breast replacement needed due to cancer surgery, but also to foster a


vigorous commercial demand by women in search of the “perfect” breasts.


A geneticist has recently proposed genetically engineering headless


humans to be used for body parts. Some prominent geneticists have


supported his idea.


Since the birth of the duplicated sheep “Dolly,” genetic engineering


(GE) has attracted attention from all levels of society. GE raises


questions of religion, ethics, and ecology that are of great concern to


many people. I would like to share a little of my understanding of GE,


hoping that it will be helpful to everyone here.


Several companies are working on developing pigs that have organs


containing human genes in order to facilitate the use of the organs in


humans. The basic idea is something like this. You can have your own


personal organ donor pig with your genes implanted. When one of your


organs gives out, you can use the pigs.


The breeding of animals and plants speeds up the natural processes of


gene selection and mutation that occur in nature to select new species


that have specific use to humans. Although the selecting of those


species interferes with the natural selection process that would


otherwise occur, the processes utilized are found in nature. For


example, horses are bred to run fast without regard for how those


thoroughbreds would be able to survive in the wild. There are problems


with stocking streams with farmed fish because they tend to crowd out


natural species, be less resistant to disease, and spread disease to


wild fish.


As more and more human genes are being inserted into non-human


organisms to create new forms of life that are genetically partly


human, new ethical questions arise. What percent of human genes does an


organism have to contain before it is considered human? For instance,


how many human genes would a green pepper have to contain before one


would have qualms about eating it? For meat-eaters, the same question


could be posed about eating pork. If human beings have special ethical


status, does the presence of human genes in an organism change its


ethical status? What about a mouse genetically engineered to produce


human sperm39 that is then used in the conception of a human child?


Bioengineers often claim that they are just speeding up the processes


of natural selection and making the age-old practices of breeding more


efficient. In some cases that may be true, but in most instances the


gene changes that are engineered would never occur in nature, because


they cross natural species barriers.


The U.S. Food and Drug Administration (FDA) issued a set of


xenotransplant guidelines in September of 1996 that allows animal to


human transplants, and puts the responsibility for health and safety at


the level of local hospitals and medical review boards. A group of 44


top virologists, primate researchers, and AIDS specialists have


attacked the FDA guidelines, saying, “based on knowledge of past


cross-species transmissions, including AIDS, Herpes B virus, Ebola, and


other viruses; the use of animals has not been adequately justified for


use in a handful of patients when the potential costs could be in the


hundreds, thousands or millions of human lives should a new infectious


agent be transmitted.”


Clearly, genetic engineering brings more harms than benefit. We should


use various channels to influence the direction of research, oppose the


cruel treatment of animals used in genetic experiments, and oppose the


policy of not labeling genetic engineered food products. However, care


is needed in reading scientific reports. Many scientific reports in the


United States have been exaggerated for the sake of competition. It is


advisable to observe clearly before offering criticism. On the other


hand, there is no need to worry that scientists might soon create a


horde of freaks and monsters. The genetic mechanism is an extremely


complex process. Genetic engineers will quickly realize their


limitations. We still have enough time to avert potential disasters.
