<P><FONT face="Times New Roman" size=4>Thanks to the development of astronautics, men are able to fly up into outer spaces against gravity. After years of improvement, the security rate of shuttles has been increasing and more and more astronauts have got the experience of traveling in space. Recently, some extremely rich people get interested in space travel and three of them have already realized their dreams. However, I suppose, this kind of travel for an individual purpose is not good for our society.</FONT></P>

<P><FONT face="Times New Roman" size=4>To start with, space travel is a waste of money. It is said that a large sum of money around 20 million dollars is needed for such a travel. This amount money may mean little to its owners, but a lot to billions of people who are still suffering from hanger and poverty. So in which way is it more meaningful to spend this sum of money? That is a proper way of thinking about the meaning of space travel.</FONT></P>

<P><FONT face="Times New Roman" size=4>On the other, space travel is also a waste of limited research resources. Space technology brings us possibilities to learn more about space and to have more science innovations. However, space travelers, as an ordinary people, can contribute little to our scientific researches but only to take up limited spaces in the shuttles. From this point of view, we should let a professional astronaut or a scientist go to the outer space.</FONT></P>
<P><FONT size=4><FONT face="Times New Roman">In summary, space travel is neither good for a good use of money, nor good for the proper exertion of resources of scientific researches. Therefore, we can see that it is not good for our society to have space travel.<o:p></o:p></FONT></FONT></P>
