Thirsty for Water?

In Iraq there are plenty of wells and in southeast Asia there are plenty of streams, but dead animals have contaminated the wells and the recent tsunami has polluted the streams with salt water. So, the question is how do we provide water for all these thirsty victims? We can provide bottled water, but it usually costs $1.50 per bottle and can become very exspensive. The Marshall Space Flight Center has been testing a device intended for the space station that would recycle astronaut's sweat, respiration, and even urine into fine drinking water that would be purer than the tap water we drink. They plan to use this big device in space and use smaller devices here on Earth in the next couple of years. What do you think about this?
