Global water resources

Water on Earth (about 1.39 billion cubic kilometers) of fresh water is only about 2.5%.
Freshwater shortage… Global population growth, food production, water intake has increased due to the industrial development, while the water source has fallen under the influence of climate.

If you look at the amount of water on Earth, “the desalination” of seawater” turns out to be good, expensive plant and infrastructure is required.
Desalination plant to the coastal cities inland areas far from the ocean’s food production would be abandoned are suitable to become a huge infrastructure costs.

In 69% of 2.5% is freshwaret glaciers in decline due to global warming, water will become one.
Turns out to be good water from groundwater pumping and land subsidence in large quantities and exhaustion, will have various problems such as pollution in the city.
No rivers or lakes, in areas such as how to take the water of the soil is dead ?

Well, such as desert Drylands, with low humidity during the day but at night, as well as other regions will increase the humidity.
In other words, this moisture may be available.
Because water in Earth’s atmosphere to become constant and are replenished as water vapor from water shortages if water.
The used water is returned to the earth any.
Water from the atmosphere, do not consume the existing freshwater, and therefore less energy is available, the global eco-friendly way.

“How the ultimate intake” is water desalination air !!
