2006.4.8(space travel)
Space travel to the moon is considered as “a step of mankind”. But some people think that space travel has made little difference on people’s lives today. To what extent do you agree or disagree?
Traveling to the outer space has brought to such popular attention that a large number of countries place it on the agenda as an important matter. Some people believe that space exploration could not bring many changes to people’s life. However, I disagree with it to some extent.
It is admittedly true that the changes that space travel brings may not so obvious that anyone in the world could reap many benefits. Most of results, as every outsider saw, are just some rocks and sand from the moon. Even, some opponents of the space travel point to the fact that there are an increasing number of matters confronted by people, which should be considered first. The money and efforts now being wasted on space travel could be wisely spent on other more essential matters, such as environmental protection, solving the problems of housing shortage.
However, the benefits that space exploration brings should not be overlooked. A large number of great inventions, some of which even play significant parts in saving people’s lives, are the direct or indirect results of space exploration. For instance, neither heart pacemaker nor freeze-dried foods could be invented without space program. Furthermore, the exploration of the outer space is an essential way for people on earth to find another planet for them to live, for the environment on earth has been destroyed to such a serious extent that human beings may be unable to rely on. Lastly, the supporters of the space programs point to the scientific knowledge that could be obtained from the outside world.
In conclusion, the space research could bring enormous positive changes not only on practical benefits but also on theoretical knowledge. Therefore, space travel is of great necessity to people living on the earth.
