Biodiversity hotspots are regions with high levels of species diversity and a large number of endemic species, meaning they are found nowhere else on Earth. These areas are considered significant for conservation because they contain a high concentration of unique and threatened species that are at risk of extinction. By protecting biodiversity hotspots, we can safeguard a large portion of Earth's species diversity and preserve ecosystems that provide critical services such as clean water, climate regulation, and pollination. Conservation efforts focused on biodiversity hotspots can help prevent the loss of species and maintain the balance of fragile ecosystems for future generations.
