Biological Diversity
Biological Diversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life. Biodiversity includes not only species we consider rare, threatened, or endangered but also every living thing—from humans to organisms we know little about, such as microbes, fungi, and invertebrates. The theme in 2022 is “Building a shared future for all life”. Fitting within the context of the ongoing United Nations Decade on Restoration, which highlights that biodiversity is the answer to several sustainable development challenges, the slogan conveys the message that biodiversity is the foundation upon which we can build back better.
