  Along with the rapid step of science development, men have got more and more achievements. Especially in biological field, scientists are creating miracles every minute. In recent years, they are decoded “the gene code” of human being. People all over the world are astonished and excited. However, at the same time, it evokes many things which we should and must think carefully. What’s gene? I think we should know sometimes about DNA first. DNA is short for deoxyribonucleic nucleic acid. It’s the most important heredity substance in our bodies, which almost decides all the shape and properties.
 
  On it are there thousands of genes arranged in sequence. Each of them carries a genetic message that decides your appearance, intelligence or any other character. So there’s no doubt that decoding the gene code will do an great effect on us and has a profound and far-reaching meaning. This scientific fruit would absolutely bring some advantages. If it was in use, agriculture would benefit from it a lot. The output of crop would increase. They could resist all kinds of diseases and have a strong ability of disaster-proteeting. Animals may be safe because scientists can continue a plant by genetic optimization or cloning when it is in danger. For humans, it will contribute to medicine. Hereditary diseases reduces a lot. Many incurable diseases can be treated. We will enjoy our lives without pain. Thus we live longer naturally. Then the population of the earth increases rapidly. This would cause the danger of resource. In nowadays, freshwater, coal, petroleum are not enough yet. How does our fragile planet under take such a great need? At that time, a good many people will suffer poverty, starvation, diseases, etc. It could even cause the third World-War. In addition to the war, we’re faced many other problems. The simplest thing is that how the target distribute. Who can decide it? Is the achievement first used on scientists or stars? Is it appreciated by nobles or tested on civilians? So simple a thing is so hard to solve. If we were to reform our genes for same reason, it might cause the disorder of(基因库). It would lead to serious aftereffects. For example, some new diseases will come and they may be incurable as cancer. Nobody can control at that time. Contemporary society has many kinds of discrimination. Discrimination of religion belief, ethnic, or (弱势群体) is harmful to the liberty of the world. Imagine that if you were a manager of a company, and you were choosing an assistant, from a crowd of people. You master everyone’s genes.
