This has sparked significant controversy, with concerns raised about potential environmental impacts (heavy metal contamination, pathogens in the food supply), and questions about the decision-making process and the roles of different government agencies (National Land Agency, Ministry of the Interior). There’s also political fallout, with accusations and demands for apologies being exchanged between officials.
