A global food shortage is coming. There is no possible way that the world can produce enough food for that many people under the current system.
Already 1 billion people in the world go to bed hungry every single night.
Already somewhere in the world someone starves to death every 3.6 seconds and 3/4 of them are children under the age of 5.
Already approximately a third of all children in the world under the age of five suffer from serious malnutrition.
And the bad news is that the world simply does not have enough water to grow much more food.
Just consider the following quote from IWMI director general Colin Chartres....
"Current estimates indicate that we will not have enough water to feed ourselves in 25 years time, by when the current food crisis may turn into a perpetual crisis."
