Natural Systems
Natural LSS like the Biosphere 2 in Arizona have been tested for future space travel or colonization. These systems are also known as closed ecological systems. They have the advantage of using solar energy as primary energy only and being independent from logistical support with fuel. Natural systems have the highest degree of efficiency due to integration of multiple functions. They also provide the proper ambience for humans which is necessary for a longer stay in space.
Natural systems are not only important for space travel, but also for life on earth. In light of the swiftly decreasing capacity of planet earth to support life, this is an important area. Good examples are biological water-treatment facilities, greenhouses or simply composting. Regenerative landscape-design (aiming at high agricultural productivity) can also be seen as part of it.
Both areas of natural LSS meet in new types of multi-trophic, zero waste greenhouses like the integrated biotectural system (IBTS). Part of this multi-disciplinary engineering is integrated multi-trophic aquaculture and the approach of energy flow (ecology).

Famous quotes containing the words natural and/or systems:
“The great man knew not that he was great. It took a century or two for that fact to appear. What he did, he did because he must; it was the most natural thing in the world, and grew out of the circumstances of the moment. But now, every thing he did, even to the lifting of his finger or the eating of bread, looks large, all-related, and is called an institution.”
—Ralph Waldo Emerson (1803–1882)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
