Terraforming Mars: Ecopoiesis

While we worry about the climate changes in our habitable planet and try to work on our ecology to cut down on gas emissions and global warming there are many scientists that actually visualize a similar process for the planet Mars. In this case there is no need for a restoration of an ecological balance but the whole process of creating conditions suitable for life and a stable ecosystem, in one word: ecopoiesis, the creation of a new earth.
There are many notable visionary scientists that dreamed of taming the red planet. Most notable of them was Carl Sagan. The late astronomer conceived a way of a biological factory of algae that will process carbon dioxide and generate oxygen and heat. In this way there will probably be a new more viable atmosphere created over time through the melting of the Martian polar caps, the vast expanses of iced water that are found to lie underneath the planet's poles. During a period of many hundred years the climate of the planet will gradually change to a more earth compatible one. The process also known as terraforming. In the picture shown there is a four step artistic illustration of the process of Mars' terraforming.(source wikipedia)
Also Martyn J. Fogg published in the Journal of the British Interplanetary Society his views on planetary engineering and presented that although mars used to be a biocompatible planet compared to Earth, a certain cataclysmic event, possibly an asteroid collision has turned it to an inhospitable place. The process of terraforming could be done anew but at immeasurable costs.
There are many issues ethical, political and financial in the way of a successful ecopoiesis. The political issues arise from the national divisions and the sovereignty of nations on the new planet. It is extremely possible that new conflicts will arise on this mater. The next thing is the economic impact of who and how will benefit from the time and resource consuming process. Will it be political nations, corporations, the settlers themselves? Finally if we come to nationality what will the future Martians be calling themselves? Americans, Russians, Greek or generally Terran? Probably none of these, a new revolution will surely start on the new motherland.
