An "iglu" is simply another spelling of "igloo," a dome-shaped shelter traditionally built from snow blocks by Inuit people. It offers surprisingly effective insulation, maintaining a warmer interior than the outside environment. Think of it as a natural thermos, trapping heat generated inside. It demonstrates resourcefulness in harsh Arctic conditions. "Iglu" and "igloo" are interchangeable terms. It highlights the Inuit's deep understanding of their environment.
