Recently I watched a program in Discovery which showed in great details how water from the wet south is being channeled to the parched north in China.
It is a great and difficult engineering endeavor, the targeted completion date is 2014. I was awed by how miles of canals were dug, tunnels were made, pumping stations erected, and dams were employed. Each geographical section's Head were brought in front of the camera and in turn they told their own struggles with a slice of the mammoth project.
I was most impressed by the water purification project that involved many research students and their Professor. If aquatic plants and tidal species could reduce the level of pollutants to the minimum allowable levels of safe drinking water, there is yet hope for our future generations in this troubled earth.
