Desperate Times For Sailors To Modern Day Navy Dominance
Sailors from 1700-1980 used distillation of seawater to create safe drinking water. Current Navy Fleets can desalinate more than a million gallons of water a day for Shipmen to drink. It can even be used in times of drought on-land. (Armed Forces members also carry stuff with them to desalinate and clean water when they have to camp out in specific locations. They are prepared for anything.)
