Gravity is also a problem. Less than 40% of Earth's, however it's the closest rocky planet with any real hope of colonization.
Earth has only so many resources and at some point we wont have a choice but to use the resources of other planets.
What options do we have? Anything else is in another solar system & would take generations to reach.
