China's Controversial $167B Mega Dam Could Starve 3 Countries And They Can't Stop It

China once built a dam so heavy it slowed the spin of the planet. Now they're building one three times bigger, and it could starve three countries downstream. On the edge of the Himalayas, on a river most people have never heard of, China has started work on the most expensive thing humans have ever built. To grab the power of a river that drops the height of a small mountain in just 50 kilometers, engineers are boring four giant tunnels straight through solid rock, in one of the most violent earthquake zones on Earth. This is the full story of how it works, why nobody could build it until now, the 1950 disaster that shows what this ground can do, and why India and Bangladesh are terrified of what happens when the water stops carrying the mud their farms depend on.
