International Day for Biological Diversity May 22, 2026

Observed each year on May 22, 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.
