Space colonization, on the Moon, Mars or space stations, is widely debated. Some argue humans have a moral duty to save our species from extinction, and space colonization is one way of doing so. Others argue that living in space is science fiction and that we should concentrate on improving life on Earth instead of potentially ruining another planet or moon.
