International Day for Biodiversity

News: It is celebrated each year on May 22. This year, 2021, the theme is “We’re part of the solution”.


  • The resolution to celebrate the day was adopted in 1992. The day was initially celebrated on December 29 till 2000 starting from 1993. It was marked on December 29 to celebrate the Day the Convention on Biological Diversity came into effect. It was later shifted to May 22 to commemorate the adoption of the convention at Rio Earth Summit.


  • It is a term used to describe the enormous variety of life on Earth.It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.
  • It is often understood in terms of the wide variety of plants, animals and microorganisms, but it alsoincludes genetic differences within each species.


  • World Wide Fund for Naturein its flagship Living Planet Report 2020 warned that global biodiversity is in steep decline. It has revealed a global species loss of 68% in less than 50 years, a catastrophic decline never seen before. It boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
  • Alarger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. The world should conserve it so as to maintain the food chain. The disturbance in the food chain may affect the whole ecosystem.
