The Gene Industry
Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls metal-hungry microbes that might be used to mine valuable trace metal from ocean water. They have already demanded and won the right to patent new lifeforms.
Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of microbe spills that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.
Should we breed people with cow-with stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assembly-line workers designed to do our monotonous work for us? Should we attempt to eliminate inferior people and breed a super-race? Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate unfit babies? Should we grow reserve organs for ourselves, each of us having, as it were, a savings bank full of spare kidney, livers, or hands?
Wild as these notions may sound, every one has its advocates in the scientific community as well as its striking commercial application. As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God? , Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created.
