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:
“Men speak of natural rights, but I challenge any one to show where in nature any rights existed or were recognized until there was established for their declaration and protection a duly promulgated body of corresponding laws.”
—Calvin Coolidge (1872–1933)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
