Debunking the lemming suicide overpopulation theory

 THEY DO NOT KILL THEMSELVES, IT IS JUST A MYTH! ...or not?

 El suicidio masivo de los lemmings ¿mito o realidad? – Vertebrados, Vida y Costumbres

It has long been assumed that lemmings commit mass suicides in order to reduce overpopulation. This idea acquired traction as a result of misconceptions, misinterpretations of natural behaviors, and media depictions. This myth, however, has been refuted by scientific studies and observations, showing a more accurate picture of lemming population dynamics.

Lemmings are small, herbivorous rodents that live in North America, Europe, and Asia's Arctic areas. They are well-known for their cyclic population swings, in which their numbers rise quickly in some years and fall in others. Lemmings may travel in search of new food sources and habitats during periods of high population density, but their movement is not motivated by a conscious attempt to control their numbers.

The idea of lemming suicides dates back to a 1958 Disney film called "White Wilderness." The film featured lemmings jumping over cliffs into the sea, which appeared to be a type of mass suicide. It was eventually proven, however, that the filmmakers staged this behavior by herding lemmings and recording them in a site far from their normal habitat. The scenes were produced for dramatic effect and do not depict real-life lemming behavior.
