Väljasuremisohtu

Väljasuremisohtu refers to the probability or likelihood of a species becoming extinct. This concept is a critical element in conservation biology and ecology. Several factors contribute to the risk of extinction, including habitat loss and degradation, climate change, overexploitation through hunting or fishing, invasive species, and pollution. The small size of a population can also increase its vulnerability, as it may lack the genetic diversity to adapt to changing environmental conditions or be more susceptible to random events.

Assessing väljasuremisohtu often involves analyzing population size, reproductive rates, the extent and fragmentation of their habitat, and threats from human activities and natural disasters. Organizations like the International Union for Conservation of Nature (IUCN) use this information to categorize species based on their extinction risk, with categories ranging from "Least Concern" to "Critically Endangered" and "Extinct in the Wild." Understanding väljasuremisohtu is essential for prioritizing conservation efforts and implementing strategies to prevent species from disappearing permanently from the planet.
