Fresh water life itself, has never come easy in the Middle East. Ever since the Old Testament God punished man with 40 days and 40 nights of rain, water supplies here have been dwindling. The rainfall only comes in winter, Inshallah—Good willing—and drains quickly through the semiarid land, leaving the soil to bake and to thirst for next November.
The region’s accelerating population, expanding agriculture, industrialization, and higher living standards demand more fresh water. Drought and pollution limit its availability. War and mismanagement squander it. Says Joyce Starr of the Global Water Summit Initiative, based in Washington D. C. "Nations like Israel and Jordan are swiftly sliding into that zone where they are suing all the water resources available to them.

In the nineteenth century, it was commonly accepted that life, perhaps even intelligent life, was widespread in the solar system, and Mars was an obvious target in the search for life. New photographic technology offered a way for astronomers to learn more about the red planet. In 1888, Italian astronomer Giovanni Schiaparelli produced images that showed a network of long, thin, dark lines crossing the surface of Mars. He called these features canali in Italian, which became "canals" or "channels" in English. The strange appearance of the canals suggested to some scientists that they had been formed artificially rather than naturally. The mystery deepened when Schiaparelli observed that many of the canals in the photographs were actually double.
