What are biodiversity hotspots and why are they significant?

Biodiversity hotspots are regions that are exceptionally rich in species diversity and contain a high number of endemic species, but are also under serious threat from habitat loss and human activities. To qualify as a hotspot, a region must have at least 1500 endemic plant species and must have lost a significant portion of its original natural vegetation. These areas are significant because they represent critical zones for conservation, where protecting a relatively small area can preserve a large proportion of global biodiversity. Biodiversity hotspots also support ecological balance, provide valuable ecosystem services, and are important for scientific research, climate stability, and sustainable development.
