Flow – For Love of Water | Watch Free Documentary Online. This is a touching film about the importance of water and how people in other countries buy it. It is shocking. The cost of providing water to a person in a third world country is less than $2 US dollars a day. Can you imagine how you would feel having to deny people the water they need? Apparently world-wide 30,000 people a day or about 10 million a year worldwide die to lack of access to water. California has 27 years of water left. Surprising how short-term our vision is.
