International Day for Biological Diversity (World Biodiversity Day)

On May 22, people across the globe pause to celebrate the incredible richness and variety of life on Earth. The International Day for Biological Diversity – also known as World Biodiversity Day – invites us all to recognize the vital web of plants, animals, fungi, and microorganisms that sustain our planet. From the food we eat to the air we breathe, biodiversity touches every part of our lives – and its protection is a responsibility we all share.

What is International Day for Biological Diversity?

Imagine walking through a rainforest, hearing hundreds of birds and insects, or savoring a meal made possible by pollinators and fertile soil. That’s biodiversity in action. This day is dedicated to raising awareness about the importance of Earth’s variety of life – from the smallest microbe to the largest whale – and the ecosystems they form. It supports everyone: farmers relying on healthy crops, children learning about wildlife, and communities facing climate change. In 2023, for example, Kenyan youth groups planted native trees to restore degraded land, showing how local action can make a global difference.

When is International Day for Biological Diversity?

The International Day for Biological Diversity takes place every year on May 22. It’s a one-day event, but the conversation and action often last much longer. Organizations, schools, and individuals mark the day with educational workshops, tree-planting, nature walks, art projects, and online campaigns. The date commemorates the adoption of the Convention on Biological Diversity in 1992 – a global agreement to protect nature.

Why International Day for Biological Diversity Matters

Biodiversity is the foundation of healthy ecosystems, which in turn support our food, water, medicine, and climate stability. Yet, species extinction rates are now tens to hundreds of times higher than in the past 10 million years, largely due to human activities. Forests are disappearing, pollinators are declining, and entire habitats are under threat. When we lose biodiversity, we lose resilience – and the ability to adapt to challenges like climate change or new diseases. Protecting biodiversity isn’t just about wildlife; it’s about securing a future where people and nature thrive together.

How to Get Involved in International Day for Biological Diversity

Everyone can play a part in protecting biodiversity, no matter where they live. Here are some ways to take action:

• Host or join a local clean-up or tree-planting event.
• Support native species by planting pollinator-friendly gardens at home or in your community.
• Use social media to share stories, photos, or facts about local wildlife and ecosystems.
• Organize educational activities in schools or workplaces, such as nature walks or biodiversity talks.
• Reduce your impact by choosing sustainable products, avoiding single-use plastics, and supporting conservation organizations.

History of International Day for Biological Diversity

The United Nations established this day in 1993 to mark the adoption of the Convention on Biological Diversity. Originally held in December, the date moved to May 22 in 2001 to honor the signing of the Convention in Nairobi. What began as a formal recognition has since grown into a grassroots movement, inspiring people of all ages to take action for nature. Today, communities from the Amazon to the Arctic use this day to celebrate local species and push for stronger environmental protections.
