17.06.2011 | Potsdam: A book with new insights into System Earth by Spektrum Academic Editors shows that there is no other planet like Earth in the universe, as far as we know. At closer inspection our home planet reveals itself as a unique system of relationships and interactions of the major subsystems, the geosphere, atmosphere, hydrosphere, cryosphere, and biosphere. Their surprisingly fine-tuned interactions were capable to bring forth life, including the evolution of humans, and life in turn modifies the subsystems yet again.
