As regards the statement ...

As regards the statement "With so many available organization focusing on the issues and technologies available why is there still a worldwide crisis's?" Yes, crisis is there because the need is greater than supply. World's supply of usable fresh water for human and all its living ecosystems is less than 1% of all the fresh water available with only 0.3 % supply from all rivers and lakes of the world. World population is increasing day by day and so to sustain its food needs our water resources are becoming limiting factor even with good water management. Charitable Organization might have some technologies available for freshwater for drinking purpose to some extent but due to its practicality and the cost, poor are always bypassed. 

Of course as Mr. Carlo Atum has stated about the atmospheric water generator (AWG) techniques for drinking safe water- what will be its implication in maintaining atmospheric climate (moisture) if it is drawn overly? Will it have some negative effect as we have seen in case of groundwater over drawn cases?

Therefore, we must try to find some sustainable sources and its harnessing technology for solving not only drinking purpose but for the future agricultural production aspects too.
