Recently,students (in our class) had a discussion on whether space is worth exploring.
On the one hand,some students think that space exploration is not worthwhile.They think space is too far away from us and our daily life. And space exploration will waste a lot of money,which can be used to solve the problems on Earth,such as starvation and pollution.
On the other hand, some of students think that space exploration is worthwhile.As we all know,satellites have been used for communications as well as weather forecast,which makes our life more convenient.Besides,if resources are found on other planets,（the problem of energy shortages on Earth )can be solved.
