It will be scary... Scary sight. I hope we will never need water. We will just in abundance.I don't know what to say more.But it bad because here comes the countdown of fresh water and if we 'll continue this pollution of water it will have finished deplorably...

The 1887 Yellow River flood took between 1 and 2 million lives.
44 years later, China was hit with another flood that was far worse. The 1931 flood is considered to be the worst flood in history The 1931 flood is estimated to have taken an astounding total of 2,500,000–3,700,000 lives.
Sadly, just seven years later, China was hit with yet another flood. The 1938 flood took almost a million people.
I have no idea why these Chinese floods claimed so many lives. I understand that China is the most heavily populated country in the world, but China also has mountains. Floods usually give some warning. Couldn't the population have sought higher ground?
By comparison, the 1927 Mississippi River flood that is considered the worst in American history cost 246 lives.
In terms of damage, the flood in New Orleans caused by Hurricane Katrina was the costliest flood in American history.
Tens of billions of gallons of flood waters outside the levees spilled into vast areas of New Orleans, flooding over 100,000 homes and businesses. This resulted in the inundation of 80% of the metropolitan area.
This is a common theme in many disasters - when man's attempt to control nature fails, many people die. For example, China's Banqiao dam ruptured in 1975. 170,000 people lost their lives. 11 million people lost their homes.
When technology and Nature compete, Nature often wins.
