A water scarcity report issued recently as a collaboration of several U.S. intelligence agencies predicts that the likelihood of conflict over water will increase in the coming decades. The report argues that the Middle East, as perhaps the most water impoverished region of the world, will be particularly susceptible to so-called “water wars.”
The strain on the global water supply is the result of a number of factors. First, most of the Earth’s water is simply unavailable for consumption, sanitation, or agricultural purposes because 97% of it is salt water. Of the remaining 3%, only 1% is available for direct human use. Moreover, in some areas of the world, the available freshwater supply is being depleted faster than it is being replenished. Saudi Arabia, for example, gets 70% of its water from 21 aquifers where water is being extracted faster than nature can restore the supply. In the case of Yemen, the state’s current water demand exceeds its renewable water resources by 900 million cubic meters per year.
As the world’s population continues to grow, the demand for water will increase correspondingly. The high population growth rates, hovering around 2% in the region compared to the world average of 1.1%, and paucity of arable land in the Middle East will make water shortages in the region particularly acute. The United Nations predicts that by 2025, 30 countries will be water scarce, out of which 18 will be in the Middle East and North Africa
“El desarrollo integral es el nombre general que se le da a una serie de políticas que trabajan en conjunto para fomentar el desarrollo sostenible tanto en los países en desarrollo como en los subdesarrollados. Debido a que el tema del desarrollo se ha vuelto tan esencial en los últimos años, especialmente a medida que las naciones del mundo se vuelven más integradas e interconectadas, la OEA tiene una secretaría completa dedicada a esta área. La Secretaría Ejecutiva para el Desarrollo Integral trabaja para apoyar, facilitar y promover el desarrollo integral de los Estados miembros en coordinación con medidas para fortalecer la democracia, la seguridad multidimensional y la promoción de los derechos humanos.”
<h2>B: the amount of moisture in the Earth’s atmosphere. </h2>
As by definition humidity is the concentration of water vapours in the air. So the best answer is B.

Economy, Mixed Economy, and Planned Economy. Basically, an economic system refers
to the different systems of production, allocation of resources, exchanges, and
distribution of goods and services. This happens in almost all societies but differs
in the policies that are being implemented and followed.</span>
Actually already this: living next to the sea already encourages this; as sea offers easy transportation and food source: one only needs to catch the fish, and does not need to tend to them throughout their life. And Greeks live on Islands and Peninsulas so they have a very easy access to the sea.
