Biodiversity hotspots are areas that have high levels of biodiversity and are important for conservation efforts. They are crucial because they contain a large number of unique species that are found nowhere else on Earth. Protecting biodiversity hotspots helps preserve these rare species and ensures the overall health of ecosystems. Additionally, these areas often provide essential ecosystem services such as clean water, pollination, and climate regulation, making them vital for human well-being. By conserving biodiversity hotspots, we can safeguard the planet's biodiversity and maintain a healthy environment for future generations.
