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:
“We are frequently told that talents and genius are natural gifts; and so indeed they are, to the same extent that the productions of the garden and the field are natural gifts.”
—U. R., U.S. women’s magazine contributor. American Ladies Magazine, pp. 317-19 (June, 1829)
“We have done scant justice to the reasonableness of cannibalism. There are in fact so many and such excellent motives possible to it that mankind has never been able to fit all of them into one universal scheme, and has accordingly contrived various diverse and contradictory systems the better to display its virtues.”
—Ruth Benedict (1887–1948)
