Fisherman Almir Mendes Barbosa holds a small turtle from an artificial pond in the Saude Village near Pedral do Lourenco, a natural rocky formation on the Tocantins River that may be blown up to build the Araguaia-Tocantins riverway, in Itupiranga, Para State, Brazil, September 30, 2025. Researchers including Alberto Akama, from the state-funded Emilio Goeldi Museum, warn the river's biodiversity would also suffer if blasting destroys these rare rapids, where endangered fish gather, turtles breed and river dolphins feed. Brazilian environmental agency Ibama authorized blasting outside the most sensitive reproductive and migratory seasons, with provisions to monitor and relocate turtle nests. REUTERS/Adriano Machado
