Genetic engineering, contrary to triumphant claims, could be the beginning of the descent of man, and disruption of the living world.
No one can stop a floodgate. Once open, it is beyond man to control the deluge. Start with one Genetically Modified Organism (GMO), another follows, and another, ad infinitum.

A GMO makes money, another enters the competition, two-, two-, new genetic traits added. Now a GMO with another GMO combined, and another, ad infinitum.
A GMO in the tropics is grown in the Cold Countries, or vice versa, profit is good, more areas expanded, new technologies introduced. Result: destruction of the ecosystem, natural food webs and pyramids disturbed, another ecosystem falls, another, and another, ad infinitum.
Genetic Engineering is actually playing god. The creator Frankenstein went farther than that – that god only exist in the mind – that man is god.
Genetic engineers have been splicing genic materials in living plant for body weight reduction, higher ascorbic acid, carotene and xanthophyll, perhaps with mint to mask the fungal antibiotics - spliced in the name of a new science in pharmacy and medicine called PHARMING - embedding these genetic materials permanently in the DNA of the carrier plant. By planting the super plant again and again we will consistently get the "benefits."
Perhaps we will get sick less often, Maybe we will not need a doctor anymore Just read the label of the Pharmed Plants and presto! do-it-yourself medication. Because when we eat the plant we get its food value and medicinal value as well. We know that we don't really need these pharmed ingredients - in kind and amount. Why serve the GM yellow rice packed with vitamins, three times a day in our staple? What measure can we guarantee us and our children health and future?

Genetic engineering is producing the ultimate biological warfare that threatens not only our society but us as a species. The technology of producing Bt Corn, Golden Rice, and the like, is basically of the same principle - the splicing of the identified vital gene to a host or carrier organism. It is not far from the hands of the terrorists that this can happen, and the detonation of a GMO bomb is not a remote possibility.

Neo-Frankenstein Syndrome: Mankind's Greatest Fear
A Genetically Modified Organism (or GMO) is a result of rapid genetic pooling or buildup of desirable traits by means of genetic engineering, rather than through the conventional method.
The conventional agricultural breeding methods are tedious, and subject to uncertainty. Today’s biotechnology opened a frontier whereby the genes of organisms can be transferred and combined according to the traits one wishes to combine. It is actually opening a floodgate of possibilities, spectacularly including cross-species or cross-phyla transfer of genes. This could mean a firefly gene implanted in a rat can make the rodent glow in the dark.
God's design of the living world, the interrelationship of its members, and that with their environment; their composition as species and individuals - these have been irreverently altered by the genius of man, by men who play God. (Destruction of God's Design in acrylic by AVR)

All these scenarios have their early beginnings with the DNA (Deoxyribonucleic acid) model proposed by F.H.C. Crick and J.D. Watson in 1953, the two later sharing the Nobel Prize in biology. So precise is the double helix model that with modern tools, one can insert a portion of the genetic material from one organism onto another, causing the latter to carry a desired trait. Thus a gene of a bacterium, Bacillus thuringiensis, spliced into the genetic structure of corn produced the Bt corn, the first genetically modified crop. The plant is claimed to be caterpillar-resistant since B. thuringiensis causes disease in caterpillars that destroy corn. Protein gene of one legume can increase the protein nutrients of another. Beta-carotene gene from daffodils, when introduced into rice produces golden rice.
The questions are, when introduced, what extent are the modifications? What kinds, and what directions will they go? Could an organism, reaching a level of modification, lose its genetic identity, thereby becoming alien to its co-members and to the natural environment? We ask these questions in the light of the following premises:
1. A single gene may control one trait, but where there are more traits controlled by multiple, blending genes, the process can get out of hand. The collective expression of modified gene combinations, not to mention the effects of disturbed loci in the genes, can be dangerous. It will take time for us to know the adverse effects of GMO on human beings and the environment.
2. Every trait of an organism, in one way or the other, has an affect on the environment, and vice versa. This means that if the protein is elevated, the higher protein levels will need more nitrogen, thereby requiring fertilizer subsidy. An increase in milk output means more cattle feeds, and antibiotic input to protect the animal from milk production-related stress. There is a saying in ecology that there is no such thing as “free lunch”.
3. Ecologically, how will a GMO relate to the natural members of the environment? How will the new organism now fit into the ecosystem in which its “parents” were once a part, integrally built by laws governing seres, niches and evolution? We may be only interested in how the organism serve our purpose for the moment, but unaware of its usefulness or destructiveness, when left alone in its own environment.
4. Genetic engineering may increase the number of plants and animals that now depend entirely on man’s care and attention. Many genetically altered breeds and varieties may no longer be able to live and prosper in the open. This is indeed an antithesis of natural farming.
Book of Life
This feat was preceded by the cracking the atom which brought out the first genie, the atomic bomb. What would the second genie look like?
1. Does GMO cause cancer and other diseases? There is no direct evidence. But cancer is too complex a disease for us to understand fully. Whatever triggers the disease is not immediately determined until we accurately read it in the human genome map. Questions are asked: “Where did prion (protein infective principle of mad cow disease) come from? “How does it cause Bovine Spongioform Encephalopathy (BSE), and the human Creutzfeldt Jakob Disease (CJD) to which the Mad Cow Disease is associated?” “Other than cancer why are there more young people contacting diabetes, Alzheimer’s and Parkinson’s diseases?” We do not know the answers to these questions. We cannot blame these to GMO either. It is too early to say. But we have to be wary.
3. Processed Food from GMO. Seemingly, you do not see this kind of genie. We do not know but we are eating GM Food, no matter how much we try to avoid it. There was no referendum conducted or public consultation before GMF was put to market. Today, GM soybean is processed into cooking oil, soy sauce, TVP (Texturized Vegetable Protein), taho, tokwa, etc. GM potato finds its way through fast food chain. There are steaks, burgers, corned beef and milk which come from GM cows. But who is accountable when things go wrong, and how can we seek redress?
GMO, Medicine and Health.
Remember that a genie can be obliging, too. Genetic engineering (GE) is as young as dawn. As light breaks, we take a glimpse before the sun is up. Genetic engineering is perhaps the key to the control of malaria and dengue. Entomologists have already isolated parasite-suppressing genes in mosquitoes.
GE in medicine, such as insulin production, has expanded into the production of more potent antibiotics and hormones. The incorporation of drugs in genetically modified food plants opens a new field of pharmacology, called biopharming. GMO mixed with vitamins can reduce infant mortality, blindness, and other associated defects.
Modern Frankenstein monster
It is inevitable that genetic engineering will be applied in human cloning. Today, we have so far applied human biotechnology mostly in helping childless couples bear children, such as through in vitro (outside of the womb) fertilization. But with current results in animal cloning, a technique is being developed to clone the human being without encountering the problems that beset Dolly the sheep, which is premature aging. If this is not handled well, we may be bringing forth a new Frankenstein monster. x x xLesson on former Paaralang Bayan sa Himpapawid (People's School-on-Air)
