In the very beginning, people lived next to water sources and when the water source could not sustain the number of humans, either the humans moved or something happened to the weak and the old that brought their numbers down.
Migration out of Africa
While no historical record exists of human migration out of Africa, scientists have tracked human migration by studying mtDNA and mutations of mtDNA.
It is thought likely that when water and food shortages occurred, humans learned from animal migrations and may have literally followed heard movements in search of water and food.
As the accompanying map shows, eventually, human migration populated all of the continents, except the inhospitable polar regions.
Migration Today
Each week about a million people move from the country into a city. Today about 50% of human population lives in cities.
By 2050, nearly 70% of the then human population will reside in cities. This will put enormous pressure on the services and supplies infrastructure of every city.
Water Supply to cities
Pipelines, canals, aqueducts are all ways we have perfected to bring water from far distances to a city. But as cities grow, every one of these water transportation choices will need expansion or replacement with cost, time and environmental impact considerations.
This is where the idea of a water refinery comes in
Water Refineries for Cities
Air currents move air (and the water contained in the air) to every place on Earth. Various forms of precipitation (like rain, snow, dew etc) then extract the water from the air and deposit it on land. Nature's invention is known as the Water Cycle.
The man-made facility that extracts moisture from air is a water refinery. With such a refinery available, there will be less dependence on the historical infrastructure that includes pipelines, aqueducts, canals, to name a few. This indigenous water supply, from a virtually limitless source, is the most likely way for cities to meet the water needs of its inhabitants.
