Yes, again. Mars is one of the main planets we are planning to move to - But the limitations is with the space travel, the rockets are not yet consistent enough to go to Mars and back, and even if we would try the cost would be astronomical in size, (pun intended) and it's really up to us. The prediction i would have to give is that - Yes, with enough effort we will be able to visit Mars and make it an habitable place for all humans. If we move to Mars, we will discover many other things. The limitation is however - Mars is in outer space, that means we have to block off Mars from space, or give everyone oxygen masks, which is another thing we have to bypass before making it habitable. The benefits are:, as we know, the Sun in a few billion years will engorge the earth and explode into another star. Us humans have to either prevent this - or move to Mars or another such habitable planet. The Benefits of visiting Mars is a good choice to move to, because of research, this will allow us to recognize more of the substances, rocks and any sort of existing life on this planet. (if any.) Scientific research is one of the main factors. How many people will visit is unknown, as it's up to us to advance and to overcome the struggle so everyone could live on Mars one day, but we are currently limited due to the technological progress. In the future, this will likely all change.
