Explanation
Initially 25 biodiversity hot spots were identified but subsequently nine more have been added to the list, bringing the total number of biodiversity hot spots in the world to 34. These hot spots are also the regions of accelerated habitat loss. Three of these hot spots are Western ghats, Sri Lanka, Indo-Burma and Himalaya-cover. Our country is exceptionally high in biodiversity regions. Although, all the biodiversity hot spots put together covers less than 2% of the earth’s land area, the number of species they collectively harbor is extremely high and the strict protection of these hot spots could reduce the ongoing man extinctions by almost 30
