Peak water (Water Scarcity) is reached when the rate at which water is demanded is higher (High Population growth) than the rate at which the supply is replenished.

Here is an article quoted from Wikipedia: "India has 20 percent of the Earth's population, but only four per cent of its water. Water tables are dropping fast in some of India's main agricultural areas. The mighty Indus and Ganges rivers are tapped so heavily that, except in rare wet years, they no longer reach the sea.

India has the largest water withdrawal out of all the countries in the world. Eighty-six per cent of that water goes to support agriculture.That heavy use is dictated in large part by what people eat. People in India consume a lot of rice. Rice farmers in India typically get less than half the yield per unit area and they use 10 times more water than their counterparts in China do. Economic development in some ways makes matters worse. As people's living standards rise, they tend to eat more meat. But it takes tremendous quantities of water to raise animals for food. Growing a tonne of grain requires 1,000 tonnes of water. To produce a tonne of beef takes 15,000 tonnes. To make a single hamburger requires around 4940 liters (1,300 gallons) of water. A glass of orange juice needs 850 liters (225 gallons) of fresh water to produce."

India is a typical example of a country experiencing Peak Water. "India has 20 percent of the Earth's population, but only four per cent of its water." This is a serious problem that needs to be solved. [More people = More demand of supply of water -----> But low supply of water = low agriculture production] We hope more people will know the experience of water scarcity and save more water.
