What is Biodiversity?

Biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. It encompasses the diversity of species, the genetic differences within species, and the variety of ecosystems.

Historical Background

The term 'biodiversity' gained prominence in the 1980s. The Convention on Biological Diversity (CBD) was established in 1992 as a global framework for biodiversity conservation.
