International Day for Biological Diversity 22 May 2026

International Day for Biological Diversity

Observed each year on 22 May, International Day for Biological Diversity is a global reminder that life on Earth is richer—and more fragile—than it appears. Established by the United Nations, today highlights why protecting plants, animals and ecosystems matters for food, medicine, climate stability and everyday well-being.
