The International Day for Biological Diversity is observed globally on May 22 each year to raise awareness about the vital role biodiversity plays in sustaining life on Earth. In 2025, the day serves as a timely reminder of the urgent need to protect and restore ecosystems amidst growing environmental challenges.

The day was established by the United Nations in 1993, following the adoption of the Convention on Biological Diversity (CBD) at the Earth Summit in Rio de Janeiro in 1992. Initially celebrated on December 29, it was later shifted to May 22 in 2000 to commemorate the date of the CBD’s adoption.

Significance

Biodiversity refers to the variety of life forms on Earth—plants, animals, fungi, and microorganisms—and the ecosystems they form. It is crucial for ecosystem stability, food security, water resources, climate regulation, and human health.

However, biodiversity is under serious threat due to deforestation, pollution, climate change, habitat destruction, and overexploitation of resources. The day aims to promote actions that conserve and sustainably use biological diversity, helping to achieve global environmental goals.

Global Observance

Across the globe, educational campaigns, tree plantation drives, biodiversity fairs, and policy discussions are held to promote awareness and action. Schools, research institutions, and environmental organizations engage the public in learning about the importance of preserving nature.

Conclusion

The International Day for Biological Diversity 2025 is a global call to protect nature today for a sustainable tomorrow.
