Life-support system
Technology that allows survival in hostile environments
Life-support system
The evolved life-support systems for our planet contrasts with the combination of equipment that allows survival in an environment or situation that would not support that life in its absence. It is applied to the algae, bacteria, carbon, nitrogen, phosphorus, and nitrogen cycles as well as the systems supporting human life in situations where the outside environment is hostile, such as outer space or underwater, or medical situations where the health of the person is compromised to the extent that the risk of death would be high without the function of the equipment. In human spaceflight, a life-support system is a group of devices that allow a human being to survive in outer space. US government space agency NASA, and private spaceflight companies use the phrase "environmental control and life-support system" or the acronym ECLSS when describing these systems. The life-support system may supply air, water and food. It must also maintain the correct body temperature, an acceptable pressure...
