To inhabit these “other worlds” there would be three options. Either we would have to change the planet to make it habitable (he created the word “terraforming”), we would have to change to suit the new environment (“pantropy”), or there would have to be a combination of these two things. Blish, along with other writers and scientists, believed that genetically engineering the colonists (pantropy) would be the easiest option.</p><p>Books about inhabiting Mars: 1) The Seedling Stars 1957 James Blish 3) A Double Sladon 1978 Frederick * Turner 2) The Lunar Professor & His 4) Genesis: An Epic Poem 1988 Remarkable Revelations Concerning the Frederick Turner Earth, the Moon, and Mars; . . . 1909 James 5) Mars Plus 1976 Frederick Pohl * B.
