Everyone requires water. Yet, humans have evolved to need fresh water. However, we supposedly evolved from creatures, which came from the ocean. Could
ancient civilizations have flourished from fresh ocean water. Yet, some war, or catastrophic event could have polluted the oceans with salt. Whole
civilizations would have died out as the few that remained retreated to inland fresh water sources.
Fresh water is again becoming scarce. Will such a history repeat? Has it happened before?
