The advantages and disadvantages of space travel  尚雨岸

  As technology is developing day by day, space travel is becoming more and more possible for us. Need we take space travels?

  It`s known to everyone that the space and the sources on earth are limited, but the universe car provide us with new accommodations and new sources of materials. Also, we can learn more about space during the travels and space travel research may do good to industry.

  Though there are lots of advantages of space travel, the disadvantages are also obvious. Space travel needs a large amount of money that can be used on other aspects, such as education, public facilities etc. Furthermore, it`s unrealistic to travel in space because nobody can surely guarantee the security of space chips.

  In my opinion, the advantages are more than the disadvantages. We, human beings, must face the problems of limited space and resources directly, after all. We will accumulate experience of researching the universe through space travel and we have to solve many problems we will meet only by doing this.
