Since 1999, Beijing has been drought for seven years. In recent years, Miyun Reservoir restores only 1 billion liters of water, which can one-year supply of Beijing. The underground water level descends continuously, which is below 20m of soil surface. Planning of South-to-North Water Transfer Project in China will finish in the end of 2007. 2008 Olympics require high water quality. In order to protect our water resource, we hope everyone not swim or pour rubbish in the channel. Protecting water is the responsibility of each citizen.
