The development of various technologies resulted, in recent decades, great advances in telecommunications, automotive and many other fields else. All progress brings new challenges such as finding new sources of clean, renewable energy, in order to avoid damage to the environment we inhabit.
Thus, the project "Biosphere 2" began in the 80's, with the aim of better understanding the functioning of our ecosystem and eventually in the future to survive on other planets in our solar system. Designed by visionary John Allen, and financed by private companies, is recreating a miniature planet Earth is located on our planet.
This artificial ecosystem is locked in a completely airtight, glass and steel above and a block of steel underneath.
A biosphere is essentially a closed system at the material, no matter enters or leaves, but open energetically. The planet earth is a biosphere. Neglecting cosmic rays that bombard us in every moment and the occasional meteor, you can consider it a closed system and open the material level of radiation that gives us the sun.
scientists considered themselves to Biosphere 2 as "an oasis above of an aircraft carrier. "The bottom is composed of sophisticated systems that include pumps, valves and water tanks simulating natural circulation. Its area of \u200b\u200b1.4 hectares includes a tropical forest, a swamp, a desert and of course for the eight habitat with human research laboratories.
The total volume is 161,000 m³. During the 4 years that it took in making the facilities were added plants, animals and bacteria to generate ecosystems as potential similar to existing ones.
In 1991, joined four women and four men to carry out experiments and study the behavior of these closed ecosystems and their interactions during a period of two years. Without bodily contact with the outside world, could talk on the phone with relatives and friends. Had to grow all their food in an organic garden and water should be recycled for use. All waste is recycled and purified by plants and microorganisms.
Jane Poynter, one of the scientific team presented their experience in the TED talk which I recommend to see.
The biggest obstacle that was found was a sharp drop Your oxygen level start shortly. The eight scientists were fully devoted to analyzing this problem and that was compromising the project. It is clear that their lives were in danger, always keeping open the possibility of out of Biosphere 2, if the situation created danger to their health.
was estimated that the loss of oxygen was 7 tons, but having the certainty that they could be in another location within the facility. The oxygen level of the standard had dropped 21% to 14% in the air they breathed.
At one point in what began to deteriorate the health of the occupants and had to inject air from the outside. Subsequently, scientists came to understand the problem: they had placed too much carbon in the soil in the form of compost, and the latter to disintegrate, retired air oxygen, carbon dioxide added was incorporated into the concrete is present in the facility. A valuable lesson, especially because it was the only significant problem during the experiment.
Poynter tells us in his talk like THROUGH the experience of feeling that had a direct influence on its ecosystem and in turn the latter influenced the person has achieved a higher level of unity consciousness regarding the world in which we live. This concept is difficult to perceive for most of us, as we are accustomed to viewing the world from the separacón of elements.
also stresses that the exhale CO2 when breathing, these atoms were incorporated into the cultivated sweet potatoes, then return in some form to your body when eaten. Even as she put it, "eating itself in a strange way."
Our planet Earth is Biosphere 2 and is the only one we have. The option to inject oxygen from the outside does not exist yet. Do not waste it and think before throwing batteries away, leaving the tap open or manage a 160km / h double emitting greenhouse gases.
