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 aim of every political association is the preservation of the natural and imprescriptible rights of man. These rights are liberty, property, security and resistance to oppression.”
—French National Assembly. Declaration of the Rights of Man (drafted and discussed August 1789, published September 1791)
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
