Global warming brings many water problems. One way around them is to use desalination. Another is to obtain water from air! Several products are in development or are on the market already. You watch – this trend will become a tsunami.
Global warming causes water shortages through droughts and disappearing glaciers. It also causes polluted water sources when there are floods, such as in the aftermath of Hurricane Katrina in New Orleans.
Indeed several reports on the impacts of global warming suggest the possibility of wars between nations over water.

Next, there are various technologies that can help. These include
*Desalination through distillation
*Condensation
*Water absorption by salt
Desalination is now widely used but water from air...
