Nearly 33% of the world's population lacks clean water and safe. 75% of diseases in underdeveloped countries are the result of the lack of potable water and poor health system.

As the population grows, undermines the ability of water supply. There are at least ten places in the world where a war could erupt over water, according to the U.S. government the beginning of the century, more than 5,000 million people suffer from malnutrition, hunger and disease from lack of water .
