Many people believe that we will live on Mars.so life on mars will be better than life
on earth in many ways. people
will have more space. however, in
some ways, life on mars may not
be better than life on earth today.
food will not be the same and it
will not taste good. also, space
travel will make people ill. the
space shuttles will travel fast but
the journey to mars will probably
be very uncomfortable.希望采纳(^_^)本回答被提问者采纳
