This document summarizes information about biodiversity exploration, utilization, and conservation. It discusses that biodiversity includes genetic, species, and ecosystem diversity. India is one of the most biodiverse countries, containing 7.5% of the world's species within only 2.2% of its land area. Two regions in particular, the Eastern Himalayas and Western Ghats hotspots, contain thousands of endemic plant and animal species. The document outlines threats to biodiversity like habitat destruction and overexploitation. It emphasizes the importance of conservation efforts, traditional knowledge, and benefit sharing regarding biological resources.

Biodiversity is “the variability among all living organisms from all sources, including, inter-alia, terrestrial, marine and other aquatic ecosystems and ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems”.
