International Day for Biological Diversity
The International Day for Biological Diversity is a United Nations–sanctioned international day for the promotion of biodiversity issues. It is currently held on May 22. Biodiversity is all the different kinds of life you'll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.
