우주 개발 필요해? |
People have explored outer space for about sixty years. This exploration has helped to satisfy the curiosity about space, but some people have raised a doubt about the effectiveness about it. However, it surely has dormant effectiveness although it seems unreliable. Thus, we should not stop to support for it because it can stimulate to develop technology and provide the solution of environment problem. First of all, the exploration can induce the improvement of technology. Really, thanks to Apollo plan that sent human being to the moon, many technologies developed, For example, it led to the invention of new materials not burn out in the extreme heat and development of communication that make transfer electronic signals far away. In addition, the researches in the space use to design a process that produces precious drugs. The condition in the space has no gravity, so we can get pure chemical compounds that cure some diseases. In other words, the exploration of outer space can create substantial effects on the real life. In addition, we can get some clues for environmental problems in the outer space. Many planets in the universe are reported that they have natural resources what we need. If we can use these resources, we do not have to excavate the earth no more. It means the earth can less suffer. The research of atmosphere in outer space has given some clues, too. Through this exploration, we could know that ozone layer should protect us. In addition, it taught us how ozone decays and regenerates. Based on this information, many scientists have tried to solve the destruction of ozone layer. In conclusion, the exploration of outer space is not invalid for the reasons that I have mentioned above. Although it seems a scene of SF movies, it certainly has some possibilities to improve our life. Thus, we should wait and support continuously. |
