Why must an organism maintain homeostasis

Homeostasis is the process through which an organism maintains certain internal conditions, such as a human body's internal mechanisms maintaining body temperature at a specific level to prevent over or under heating; this process is important because it makes it possible for cells and organs to function properly. For example, certain parts of the human body cease to function if they become too hot or too cold; this is why it is possible for people to freeze to death or die from overheating.
