Lovelock, James E.. The ecopoiesis of Daisy World(en inglés). Consultado el 21 de julio de 2011. «This fiction [The Greening of Mars] was intended as entertainment, but it appeared by chance at a moment when many were giving serious thought to colonizing nearby planetary bodies. Among them was Robert Haynes, who visited me en 1984 to discuss what would be needed to establish an exosystem on Mars. He brought with him his splendid newly minted word "ecopoiesis". The term refers to the fabrication of a ecosystem or biosphere on a lifeless planet, thereby establishing a new arena in which biological evolution ultimately can proceed independetly of that on Earth.» en John M.
