The future life on Mars
What will our life be like on Mars in the future?
With the rapid development of hi-tech,the Mars will change a lot in many ways in the future.
We'll completely live in the cyberspace.
First,we find the Mars haven't been polluted.Air and water becomes more tidy and fresh than
our earth.Second,if we want,we can study in the spaceship.And people don't need to go to the
factory to work,instead of working by computer at home.On the other hand,it is very easy for us
to visit the Earth and other stars by riding spaceship.
I hope all this can come true.But first,we must treasure and protect Mars and avoid it becoming
another polluted earth.If all of us try our best to do it,we will enjoy our life.
