Nowdays there are public debate concerning space travel. Some people believe it has a great deal of advantges.However,others say it has factors of impracticality.Frankly,i am standing on the side of the oppsite.
Firstly,space travel satisfies an aggressive dream deeply rooted in the mind of mankind.And human being have an overwhelming enthusiasm in exploiting various unknown areas such as diving into the bottom of sea,drilling into the earth'score and so on.To some exent,i feel,the natural mysterious beauty has been explored completely and it has lost the original respect of human.
Secondly ,to achieve space travel take a large number of expenses.Many super rich billionare would rather spend hundreds and thounsands of money,like flowing river,on tripping to space than subscribe money in poor people.Although few countries enough developed can afford to do research in outer space,people in the developing country even can't avoiding starvation.How unfair it is! Think of what could be done with these money.
Thirdly,space travel show vanity of a minority of people,even to the whole mankind. Perhaps travelling to space which has been a exaggerative mark of others' admire doesn't mean a person could learn much knowledge from it. Actually,space travel is a special experience that we might acquire the apppetite for adventure and the courage of overcoming difficulties.
For above reasons,i regard space travel as inpraticality.What's more we should pay more attention to substantial deeds,not to waste too much money on that.
