Biodiversity refers to the variety of living species in a specific area. Areas with greater biodiversity include those with more genetic diversity, ecosystem diversity, species diversity, habitat diversity, and landscape diversity. Many species are currently endangered or at risk of extinction due to factors like habitat loss, overexploitation, and climate change. Biodiversity is important because each species plays a role and the extinction of one species can negatively impact others. Some ways to promote biodiversity include protecting species and their habitats, educating others, following conservation laws, and reducing consumption of natural resources.
