International Day for Biological Diversity or World Biodiversity Day is observed on 22nd May every year to increase awareness and understanding of the issues of biodiversity.

• Biodiversity is essential for sustaining the balance of the planet. It is the cornerstone of ecosystem services, which are completely tied to human well-being.
• The theme in 2022 is “Building a shared future for all life”. Fitting within the context of the ongoing United Nations Decade on Restoration, which highlights that biodiversity is the answer to several sustainable development challenges, the slogan conveys the message that biodiversity is the foundation upon which we can build back better.
