Expert Answer:

A biodiversity hotspot is a region of the Earth that is extremely biologically diverse and also under severe threat due to habitat loss, climate change, or extensive species loss. Guarding these regions against further damage is considered environmentally and culturally important, as they host organisms that are not found anywhere else on Earth.
 
The Western Ghats and Eastern Himalayas are hot spots in India.
