Why Killing doesn’t work: The Vacuum Effect
Well-documented among biologists, the vacuum effect describes what happens when even a portion of an animal population is permanently removed from its home range. Sooner or later, the empty habitat attracts other members of the species from neighboring areas, who move in to take advantage of the same resources that attracted the first group (like shelter and food). Killing or removing the original population does nothing to eliminate these resources; it only creates a “vacuum” that will inevitably draw in other animals living nearby. Learn More
