China suffers from thirst. A critical shortage of water resources in the arid north-east of the country began to slow down their economic development, forcing the government to begin the implementation of the largest engineering project in modern history.
With the help of hydraulic structures flow from Yangtze River will be re-directed to the north of China. Canals and aqueducts thousands of kilometers long, incredible engineering project.
About 20% of the entire population of the planet live in China, while the fresh water reserves account for only 7% of the world.
