So far, nobody knows whether there would be enough water or oxygen on Mars for people there.Moreover, scientists are not sure whether plants could grow on Mars.Food would most probably be in the form of pills and would not be so tasty.Gravity could be another problem.The gravity on Mars is only about three-eighths of that on the Earth.People would have to wear boots that are specially designed to prevent themselves from floating off into space.Compared with life on the Earth, life on Mars would be better in some ways.People would have more space.They might live in houses with huge comfortable rooms.Also, robots would do most of their work so that they could have more time to relax.There would probably be no schools on Mars.Every student would have a computer at home connected to an interplanetary network.They would study at online schools with "e-teachers".Life on Mars would be interesting as well as challenging.
