Will we run out of water before fuel?

the problem with water is contamination. we are polluting the water, potable and the oceans. soon enough we wont have enough potable water, yes even your "mighty" first world countries will have problems. because of the cost of desalinization and/or cleaning the water to make it usable by humans water will cost more than oil. good luck to us all paying 4 bucks for a gallon of water. let me remind you that a person requires about 3 liters of water per day minimum to survive. forget about taking a shower,washing your clothes or your car. unless you are made of gold of course.
