The Rural Voice, 1988-08, Page 28THE GOOD AND THE BAD OF 66 BIO- TECH WHAT CAN BIOTECHNOLOGY DO FOR FARMING? IS IT DANGEROUS? IS IT DESIRABLE? It frightens me." That's one of the most common responses whenever biotechnology is mentioned. This position is not unreasonable, especially when you consider the staggering number of experiments reported in which genes from one animal are inserted into the genes of another. Such reports usually include a prediction about what this biotech- nological marvel will mean to all of us. So if someone, somewhere, has managed to put chicken genes into a frog, you're likely to hear that some day we'll be raising frogs with per- fectly formed chicken legs and that chicken farming as we know it will become obsolete. Then someone will accuse the scientist of playing God. Opposition to the work (and biotechnology in general) will be voiced, and litigation or worse threatened if the project were ever to be put into action. Lurking in the background are fears of mutations, uncontrolled diseases and pests, and the prospect of human genetic engineering. by Ian Wylie-Toal If this were the reality of biotech- nology, it would be sensible for us to be afraid. But the reality is much more mundane. It is true that biotech- nology, in combination with genetic engineering, has given us a new way to shape the world and new possibil- ities for the modification of organisms so they will work to our advantage. But what is possible is not always probable: it may be possible to create a frog with chicken legs, but the bio- logical problems involved in doing so are enormous, so enormous that the probability of doing it successfully is nearly zero. This point is underscored by Dr. John Phillips, a professor of molecular biology at the University of Guelph. He says that biotechnology is very much an experimental area, and it is important to realize that there is a lot of hype about the subject. Experi- ments will be publicized by the media, he adds, but most of them will just fade away and have little or no impact on our lives. So if biotechnology is not a mon- ster, and it is not the be-all and end-all of human existence, then what is it? The way to start explaining bio- technology is to say that it is simply biological technology: the controlled rearing of an organism so that it does something useful for humans. In the broadest sense, all of agri- culture can be considered biotechno- logical, because plants and animals convert what humans cannot use (soil, grasses) into what we can use (seeds, leaves, meat, milk). More sophisti- cated but still ancient forms of bio- technology are used to make beer, wine, bread, cheese, and yogurt. To get these products, living organisms (yeasts and bacteria) are added to a raw material. As the organism lives and grows, it produces substances that modify the flavour and quality of the raw material. In more recent times, shortages in the Second World War prompted the biological manufacturing of glycerol and acetone along with the develop- ment of the antibiotic industry.
