Amy:There's less gravity on Mars. We'd probably need to wear
special boots.
Daniel:Yes. And we might need sleeping bags too.
Amy: I agree. Also, there is no fruit or vegetables, so we would have
to eat dried food.
Daniel: Well... that sounds quite boring! But there would be no
pollution on Mars.
Amy: I hope so.
