When the construction of China's Three Gorges Dam was completed in 2006, most Chinese citizens must have hoped it was worth the huge cost: 1.4 million people had to be relocated from towns, cities, and villages to make way for the enormous structure, which would supplement a hungry China's growing energy needs.

But their prayers have not been answered.

Six years later, the government says a further 100,000 people may be displaced over the next few years, including 20,000 this year alone, because of increasing landslide risks in the area around the dam, Reuters reports.
