How come their water wuality is SOOOO good!!!Not able to compare with Yangtze and Yellow now...
Do you think the 3 Gorges dam allows the sands to deposit and clears up Yangtse water?
They also have numerous industrious cities arround the great lakes...but no pollution...
Do the Americans have 血吸虫病 also?
