In the current era, the loss of biodiversity is not only an ecological crisis but also a profound cultural one. As species disappear, so too do the cultural practices, stories, and traditional knowledge systems tied to them. This section explores the concept of biocultural diversity, the intertwined richness of biological and cultural life—and the critical role of practical knowledge within it. Drawing from environmental humanities, the philosophy of John Dewey, and the biocultural ethics framework developed by Ricardo Rozzi, it highlights the significance of embodied, place-based, and experiential knowledge systems in fostering ecological conservation and public awareness. Through practices such as ecological art education projects, traditional art and crafts, and land-based Indigenous learning, practical knowledge becomes vital for both biodiversity and cultural diversity.
