Ethics of terraforming

The ethics of terraforming has constituted a philosophical debate within biology, ecology, and environmental ethics as to whether terraforming other worlds is an ethical endeavor. Foundations of modern biology There are five unifying principles Ecology (from Greek grc οἶκος oikos, "house(hold" and grc -λογία -logia) is the scientific study of Environmental ethics is the part of Environmental philosophy which considers the ethical relationship between Human beings and the Natural environment The terraforming (literally "Earth-shaping" of a Planet, moon, or other body is the hypothetical process of deliberately modifying its Ethics is a major branch of Philosophy, encompassing right conduct and good life

On the pro-terraforming side of the argument, there are those like Robert Zubrin and Richard L. S. Taylor who believe that it is humanity's moral obligation to make other worlds suitable for Terran life, as a continuation of the history of life transforming the environments around it on Earth. Robert Zubrin (born 19 April 1952) is an American Aerospace engineer and Author, best known for his Advocacy of manned Mars Richard Lionel Sidney Taylor is the author of "Moon Maps" and a leading supporter of Terraforming other planets They also point out that Earth will eventually be destroyed as Nature takes its course, so that humanity faces a very long-term choice between terraforming other worlds or allowing all Earth life to become extinct. Dr. Zubrin further argues that even if native microbes have arisen on Mars, for example, the fact that they have not progressed beyond the microbe stage by this point, halfway through the lifetime of the Sun, is a strong indicator that they never will; and that if microbial life exists on Mars, it is likely related to Earth life through a common origin on one of the two planets, which spread to the other as an example of panspermia. Panspermia ( Gk. πάς/πάν (pas/pan all and σπέρμα ( sperma, seed is the Hypothesis that "seeds" of Life exist already Since Mars life would then not be fundamentally unrelated to Earth life, it would not be unique, and competition with such life would not be fundamentally different from competing against microbes on Earth.

Dr. Zubrin summed up this view:

"Some people consider the idea of terraforming Mars heretical - humanity playing God. Yet others would see in such an accomplishment the most profound vindication of the divine nature of the human spirit, exercised in its highest form to bring a dead world to life. My own sympathies are with the latter group. Indeed, I would go farther. I would say that failure to terraform Mars constitutes failure to live up to our human nature and a betrayal of our responsibility as members of the community of life itself. Today, the living biosphere has the potential to expand its reach to encompass a whole new world. Humans, with their intelligence and technology, are the unique means that the biosphere has evolved to allow it to make that land grab, the first among many. Countless beings have lived and died to transform the Earth into a place that could create and allow human existence. Now it's our turn to do our part. " (Emphasis in original. ) ^[1]

Richard Taylor more succinctly exemplified this point of view with the slogan, "move over microbe. "^[2]

Some critics label this argument as an example of anthropocentrism. Anthropocentrism (from Greek άνθρωπος anthropos, "human being" and κέντρον kentron, "center" Anthropos (the term These critics may view the homocentric view as not only geocentric but short-sighted, and tending to favour human interests to the detriment of ecological systems. In Astronomy, the geocentric model of the Universe is the superseded theory that the Earth is the center of the universe and other An ecosystem is a natural unit consisting of all plants animals and micro-organisms( Biotic factors in an area functioning together with all of the non-living physical ( They argue that an anthropocentrically driven approach could lead to the extinction of indigenous extraterrestrial life.

Martyn J. Fogg rebutted these ideas by delineating four potential rationales on which to evaluate the ethics of terraforming - anthropocentrism, zoocentrism, ecocentrism, and preservationism, roughly forming a spectrum from placing the most value on human utility to placing the most value on preserving nature. Martyn J Fogg (born July 3 1960 is a widely acknowledged expert on Terraforming. Nature, in the broadest sense is equivalent to the natural world, physical universe, material world or material universe. While concluding that arguments for protecting alien biota can be made from any of these standpoints, he also concludes with an argument, similar to Zubrin's, that strict preservationism is "untenable", since "it assumes that human consciousness, creativity, culture and technology stand outside nature, rather than having been a product of natural selection. If Homo sapiens is the first space faring species to have evolved on Earth, space settlement would not involve acting 'outside nature', but legitimately 'within our nature. '" ^[3]

Criticism

Strong ecocentrists like Richard Sylvan feel there is an intrinsic value to life, and seek to preserve the existence of native lifeforms. Ecocentrism is a philosophy that recognizes that the Ecosphere, rather than any individual organism is the source and support of all life and as such advises a holistic and Richard Sylvan, ( 13 December 1935 - 16 June 1996) was a Philosopher, Logician, Environmentalist, and Anarchist This idea is usually referred to as biocentrism. Biocentrism (from Greek βίος bio, "life" and κέντρον kentron, "center" is a term that has several meanings but is commonly defined In response to these objections, weak anthropocentrism incorporates biocentric ethics, allowing for various degrees of terraforming. James B. Pollack and Carl Sagan might be described as moderate anthropocentrists. James B Pollack ( July 9, 1938 &ndash June 13, 1994) was an American Astrophysicist who worked for NASA 's Carl Edward Sagan ( November 9 1934 &ndash December 20 1996) was an American Astronomer, astrochemist, author Christopher McKay strikes a position between these two, what may be termed weak ecocentrism, proposing that an entire biosphere of alien life, even if only microbial life, has far more value than individual microbes, and should not be subject to interference by Earth life. Christopher McKay can refer to Christopher McKay (planetary scientist, planetary scientist at NASA Ames Research Center Christopher McKay (footballer However, he also proposed that it would be valuable and desirable to terraform a planet to nurture the alien life, to allow it to thrive as well as to exhibit a broader range of behavior for scientific study, and that such activity is ultimately justified by the utilitarian value to humans of being able to study and appreciate the undisturbed alien life.

McKay put his views in these words:

"If we discover living or dormant organisms on Mars and these forms represent a different type of life than the life we have on Earth, then we should not bring life from Earth to Mars. Instead, we should alter the Martian environment so that this native Martian life can expand to fill a planetary scale biosphere. . . .

". . . it is essential to maintain the categorical distinction between killing individual microorganisms and extinguishing an entire alternative system of life. There is no logical argument against killing microorganisms per se, either for research, medical, sanitary, or even casual reasons. However. . . it does not logically follow that destroying or displacing the first example of life beyond Earth is acceptable if the only examples of that life are microscopic. . . .

"If we terraformed Mars to allow the expansion of that life we would then reap the maximum benefits from the scientific study of that life form and its development into a full scale global biosphere. We would also enjoy the educational and [aesthetic] benefits of life in a biologically richer solar system. " ^[4]

On the other hand, for those opposed to terraforming, the impact of the human species on otherwise untouched worlds and the possible interference with or elimination of alien life forms are good reasons to leave these other worlds in their natural states; this is an example of a strong biocentric view, or object-centered ethic. Critics claim this is a form of anti-humanism and they assert that rocks and bacteria can not have rights, nor should the discovery of alien life prevent terraforming from occurring. Since life on Earth will ultimately be destroyed by planetary impacts or the red giant phase of the Sun, all native species will perish if not allowed to move to other objects, though some have argued this may not be true. A red giant is a luminous Giant star of low or intermediate mass (roughly 0 ^[5]

Future prospects

The contrasts between these arguments are fully explored in the field of environmental ethics. Some researchers suggest that both paradigms need to mature into a more complex, cosmocentric ethic which incorporates the (unknown) value of extraterrestrial life with the values of humanity and all things in the universe. A Cosmocentric ethic is a belief that the natural state of our universe should remain as it is without human attempts to terraform planets for human habitation Debates often focus on how much time and effort should be expended on investigating the possibility of any microscopic life on a planet before deciding whether to terraform, and what level of sophistication or chances for future development alien life would deserve varying levels of commitment to non-interference. Such debates have been engaged in live, between Zubrin and McKay and others, at various conferences of the Mars Society, which has made written and video records of the debates available. The Mars Society is an international Space advocacy Non-profit organization dedicated to encouraging the exploration and settlement of Mars. For example, a written account of some of these debates is available in On to Mars: Colonizing a New World, as a joint article, "Do Indigenous Martian Bacteria have Precedence over Human Exploration?"
