Biodiversity hotspots are areas that have high levels of biodiversity, meaning they contain a large variety of plant and animal species. The significance of biodiversity hotspots lies in their importance for conservation efforts. These areas are considered critical for preserving global biodiversity because they harbor a large number of unique and endangered species that are not found anywhere else. By protecting biodiversity hotspots, we can help safeguard the rich diversity of life on Earth and prevent the extinction of many species.
