[H2]Population fluctuations[/H2] Lemming populations go through rapid growths and subsequent crashes that have achieved an almost legendary status, largely because of the [A title="Walt Disney Pictures" href="vny!://en.wikipedia.org/wiki/Walt_Disney_Pictures"]Walt Disney Pictures[/A] film, [A title="White Wilderness" href="vny!://en.wikipedia.org/wiki/White_Wilderness"]White Wilderness[/A], which was produced in [A title=1958 href="vny!://en.wikipedia.org/wiki/1958"]1958[/A] and reappeared on television at regular intervals for many years afterwards. White Wilderness popularized, using staged footage, the myth that during population booms [A title="Norway lemming" href="vny!://en.wikipedia.org/wiki/Norway_lemming"]Norway Lemmings[/A] become suicidal and leap en masse off cliffs into the sea. For this reason, the term "lemming" is often used in [A title=Slang href="vny!://en.wikipedia.org/wiki/Slang"]slang[/A] to denote those who mindlessly follow the crowd, even if destruction is the result.
