Soil biodiversity, estimated at 25% of all known species on earth, is crucial for life aboveground, and there is growing scientific evidence indicating that soil biodiversity and the ecosystem functions and services it provides can optimize successful implementation of the United Nations Sustainable Development Goals (SDGs). In her upcoming Discovery Park Distinguished Lecture, Dr. Diana Wall, renowned ecologist and inaugural director of the School of Global Environmental Sustainability at Colorado State University, will discuss the state of knowledge on the emerging field of soil biodiversity along with implications for sustainability under current and future environmental change.
