Water is essential for food production. I disagree with the video's belief that the world has a food shortage. We have plenty of food however the food is not always available in those countries that actually need it.

We have so much food we burn it up as ethanol in gasoline. How stupid is that so we can save 10 cents a gallon on gas. Next thing you know we will be doing fracking for natural gas and using clean water for transporting the waste byproduct. Yeah right we are too bright for that.
