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:
“And if anyone should think I am tracing this matter too curiously, I, who have considered it in various shapes, can only answer with Hamlet ... “Not a jot”; it being no more than the natural result of examining and considering the subject.”
—Sarah Fielding (1710–1768)
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
