what is biodiversity hotspot? why is India considered as mega biodiversity hotspots?
The term biodiversity hotspot specifically refers to 25 biologically rich areas around the world that have lost at least 70 percent of their original habitat.
The remaining natural habitat in these biodiversity hotspots amounts to just 1.4 percent of the land surface of the planet, yet supports nearly 60 percent of the world's plant, bird, mammal, reptile, and amphibian species.
India is considered a mega-diversity hotspot due to the great diversity of organisms found here, ranging from eastern to western ghats to northern and southern India as well.
