英语作文：太空探险的利弊

The universe travel is a dream of all human beens,maybe you have imaged since you are a small baby!Now this dream which seems impossible becomes true!Wow ,that's really sounds great!But is it really good for us?I will give out the advantage and disadvantages in my mind：through space travel we can find out more living things in the universe,and we also can make friends with them so that we can advance our scientific knowledge!But another way it may cause war just like Star Wars Clone Wars!And we can find out more elements（元素,不知道你们学过没）that our earth didn't have!But it may cause economy war,someone may fight with others because of it!
That all!
