International Day for Biological Diversity
May 22 · Level 7 · #774 of 2238
This United Nations observance highlights the variety of life on Earth and why it needs protecting. Food, clean water and resilient ecosystems depend on countless living things, including plenty that rarely get a moment in the spotlight.
How it is celebrated: nature reserves, museums and environmental groups organise guided walks, talks and wildlife surveys. People learn to recognise local species and join projects that restore their habitats.
Biodiversity means more than a long list of species. It also includes genetic differences within a species and the variety of ecosystems in which organisms live.
