Biological diversity or biodiversity is that part of nature that includes the variety of genes among the individuals of a species, the variety and richness of all the plant and animal species in an ecosystem and various types of ecosystems on the earth. It has been estimated that only around 1.75 million species out of the potential 8.7 million species of all the plants and animals have been identified and described so far, the majority of which are insects.

The biodiversity of a region is influenced by climatic factors as well as human interventions. The diversity of life on earth is essential for the healthy functioning of ecosystems and it is biodiversity that boosts ecosystem productivity.

India is one of the 17 world's recognised mega-diverse countries, home to roughly 7-8% of all documented species and four of the 36 globally defined biodiversity hotspots.
