Beetles (Dynastes neptunus) walk on a wood at Tierra Viva farm in Tunja, Boyaca Department, on July 18, 2024. Beetle larvae feed on the organic waste of thousands of inhabitants of Boyaca, contributing to solid waste management, a worldwide problem close to collapse in this Colombian department. After that, their faeces are sold as natural fertiliser to farmers in the region with the intention of getting them to abandon chemical fertilizers. (Photo by Luis ACOSTA / AFP)
