  2. PROBLEM SITUATION • The passing of time has given to humankind the capacity to understand and modify its environment in order to improve the standard of living among the different organized societies. However, the same passing of time is carrying itself other important challenges and inquiries whose motivations converge to a single common basis: the survival of human race. This survival is being jeopardized by the following hazardous situations (that might happen now and in the coming future):

  3. PROBLEM SITUATION OZONE DEPLETION METEOR IMPACT GLOBAL WARMING • Increase in global temperature brings an intensification in the frequency of extreme weather conditions that can deteriorate the livable conditions in the planet. • The last mass extinction led to the demise of the dinosaurs and has been found to have coincided with a large asteroid impact; this is the Cretaceous-Tertiary (K-T) extinction event. NUCLEAR WARS LACK OF NATURAL RESOURCES • The main concern about the ozone depletion is the is the bad effects that the UV light have on human health, such as skin cancer, and planet’s life, such as the extinction of some species that are very sensitive to this type of light. • The possibility of a nuclear war has been brought to the table after the creation of the atomic bomb during World War II. • Natural resources in the Earth, such as water, oxygen, fossil fuels etc., are not unlimited and its current consumption rate is greater than the rate at which they are being replenished. http://www.motherplanet.net/g_Earth_Globe.html

  4. PROBLEM SITUATION • Because of the latter reasons the idea of creating a suitable environment for humans that resembles the life in the Earth is becoming a strong necessity in order to guarantee the survival of human race an avoid its extinction.

  5. CUSTOMER REQUIREMENTS • The system shall maintain artificial ecological models of the Earth’s biosphere. • The system shall be designed and built to serve as a sealed long term ecological environment • The system shall create a ground-base life support environment, that provides a high quality of life for humans under extreme conditions (High temperatures, High levels of CO2 etc.) • The system must be capable of measuring and maintaining a range of internal environmental conditions • The system shall provide the most inert and non-toxic background possible for the residents. • The system shall be able to generate its own water and energy supplies • Habitants of the system shall be able to grow all their food and recycle their wastes.
