Each year, 22 May is celebrated as World Biodiversity Day. The word ‘biodiversity’ defines the variety of life on earth, but in its broader sense it is the reason life exists because in the living planet nothing can exist on its own.  It is a term used to describe the different plants, animals, marine life, microorganisms, insects, habitats, ecosystem etc. that makes our planet so unique and so fascinating.
 India is one of the mega-diverse nations in the world. It is called so because the country’s gamuts of life forms are wonderfully different wherever you might be. From extreme cold to extreme heat, coastal areas to rain forests, tropical jungles to mangrove belts, the extraordinary weather and climatic conditions have created homes and habitats for more than 50, 000 species of plants and 40,000 species of animals.
Here are some fascinating facts about biodiversity of India.
