China's $167 Billion Tibetan Dam Alarms Scientists, Neighbors

China has commenced construction on the Motuo Hydropower Station in Tibet, despite concerns about ecological damage and geological risks. This $167 billion project, planned to be the world's largest hydroelectric dam, is located on the Yarlung Tsangpo River, also known as the Brahmaputra and Jamuna in neighboring countries. Experts warn of significant geological instability in the area, citing potential landslides and seismic activity. The dam's construction is opposed by numerous scientists, including a Chinese hydrology expert who claims it violates both international and Chinese laws. Concerns exist regarding the dam's impact on downstream populations in India and Bangladesh who rely on the river. The project threatens the unique biodiversity of the Yarlung Tsangpo Grand Canyon, a globally significant ecosystem. Critics argue the dam's construction violates China's nature reserve regulations and international environmental agreements. The dam's design, intended to maintain downstream flow, is disputed; calculations suggest a significant portion of the river could run dry. The potential ecological consequences are described as catastrophic, exceeding those of the Three Gorges Dam. The project's approval and commencement have sparked international controversy and raised serious questions about its feasibility and environmental impact.
