We have become familiar with the term biodiversity today due to the Convention of Biological Diversity [CBD] that was accepted by the UN Council on December 29, 1993, after which many nations, including Bangladesh, started becoming its signatories. As biodiversity is the foundation of life and is essential for the services provided by ecosystems, this year's theme of the International Biodiversity Day is “Mainstreaming Biodiversity; Sustaining People and their Livelihoods.”
