Decoding of Genes: Hope or Dread?
Can a person live up to 12007 It must be viewed as a ridiculous question just several years ago。 But now， two years after the completion of mapping the human genetic code， some researchers predict that this may eventually come true in the future。 On June 26th， 2000， the Human Genetic Project (HGP)，an international organization specializing in research of human genes， announced that 97％ of the human genomes had already been decoded and any utilization of the related gene map would be completely free。 The news immediately made a sensation throughout the world and even today， the discussion over the controversial application of the gene map and the related genetic tech seems to be forever on the wing。 Undoubtedly， the completion of the human gene map marks a milestone in our quest about nature and ourselves， but the point is what this breakthrough will bring to us all:hope or dread?
Perhaps the most promising aspect of genetic tech lies in an impending medical revolution it will incur， as many people now believe in that it serves as a new approach to control various diseases， to produce organs for transplantation or to slow down the aging process。 What's more， its feasibility to be adopted and incorporated into medical procedures has a good prospect。 Visualize one of our regular calls at hospital in the future， using only a blood sample， doctors can easily detect genes of hereditary diseases and mutations concerned， and follow up with a genetic therapy to eliminate mutated genes and thus the disease itself。 Theoretically， by reorganizing our genes to the optimum pattern，man's life span can be prolonged to large extent。
Besides the revolution it will bring in the medical field， genetic tech will also accelerate the development of a number of other scientific branches， biology among them， by providing scientists with a brand new perspective in terms of genes。 For example， by comparing human genomes with those of other species， anthropologists may acquire more profound knowledge about human evolution。
However， before people cheer for the hope genetic tech bellows， we might have already found us bogged down in so many ethical dilemmas。 Let's take the following into consideration。 If everyone lives for 1200 years， then the world population must explode。 How can our earth stand that? If parents could examine the genes of their baby before its birth， then who can decide what kind of baby should be born， while some others shouldn't?If we understand bird genes， probably we will someday soar in the sky by having our own wings。 But what if we understand those of tigers， wolves or insects? Seems that those Hollywood thrillers have made a good prophecy。 If everyone's genetic data is open to public inspection， then how can we protect our privacy? And moreover， will discrimination， invasion， or plunder of certain genes take place? And worst of all， if life of an individual can be precisely predicted the moment he is born or even prior，like he will die of lung cancer or he will develop kleptomania in his teens， then where is the fun of life? We may lose life's uncertainty， the hope that we can strive for something better as well as the belief that we can hold in hands our own destiny。 We may lose all these。 Are we nothing but genes? Or do we have something more than that? Such ethical and psychological puzzles will continue to haunt the human society。
