Here’s a Shanghai Daily headline from Sept. 7: “City Warned of Water Resource Shortage.”
The article said: “Shanghai may face a shortage of water resources if the population continues to soar. … The current capacity of the city’s water supply was about 16 million tons per day, which is able to cover the demand of 26 million people. However, once the population reaches 30 million, the demand would rise to 18 million tons per day, exceeding the current capacity.”
Shanghai will hit 30 million in about seven years!
