+A **Population Bottleneck** occurs when a population undergoes a sharp decrease in size, often caused by environmental events like a [Natural Disaster](/wiki/natural_disaster) or a period of intense [Predation](/wiki/predation). This reduction drastically limits genetic diversity, leaving the surviving population more susceptible to disease and less adaptable to future environmental changes, potentially leading to [Extinction](/wiki/extinction).
