Life support systems are the most crucial aboard any space vehicle. They typically include artificial gravity, and atmospheric controls. Failure of these systems prompts a computer safeguard to order the evacuation of the vessel in question. (VOY: "The Haunting of Deck Twelve"). Aboard some vessels the imminent failure of the life support system constitutes a blue alert situation. (TNG: "Brothers")
Life-support systems and pressure domes can be used to make a class K planet more hospitable for Humans. (TOS: "I, Mudd")
Hirogen body armor has internal life support and it can protect a Hirogen hunter while seeking prey in most hostile environments, including the surface of a collapsed star. (VOY: "Prey")
