If there is no water there can be no life. The moon is a sterile desert because there is no water in it. It is to be remembered that it was water that determined the location of human settlements and without the Nile the Egyptian Civilization would not have developed The Nile provided the Egyptians facilities for irrigation and transport. As Herodotus said, Egypt is the "Gift of the Nile".The urban man rarely thinks of the importance of water. When he needs water, all he has to do is to turn on the tap. The only time the urban folk become aware of the importance of water is when there is a drought and their water supply is regulated. If water rationing becomes too drastic. they may find themselves in a worse position than the rural man who may have a steady supply of water from his well.
Imagine a day when the taps ran dry: Mr. Townsman would have found life intolerable. He could not brush his teeth, have his shave or could he have his bath in the morning. After lunch, he would have had a very difficult time trying to wash up. He might have used cloth to wipe his crockery. He could not wash his car. At the end of the day, however, our Mr. Townsman would have realized that water is precious and he should not be a water-waster.
Scientists find water the most fascinating fluid in the world because of its versatility and usefulness. Electricity is generated by the force of running water. Unlike other substances, water expands when freezing takes place. In ancient Rome snow was used to pack prawns and meat. Ice is used for refrigeration. Water is converted into steam and used as power.
Whatever man eats is dependent on water for its growth. Water can convert whole, barren tracts of land into luxurious, rich and fertile regions, through the use of irrigation. In parts of Spain, diminishing quantities of rain have caused fertile land to dry up in the past years, creating barren deserts. This is turn has caused many men and their families to move to new places.
Most of us who take our daily supply of water for granted. may not be able to fully appreciate the importance of water. Many have perished through lack of water.
Military men know that the most effective way of subduing any city or fortress is to cut its water supply.
Thinking about the end of the world is – scientifically speaking – quite good fun. Setting off all the world’s nukes would be pretty bad for humanity, but if you really want to bring about the apocalypse, setting off every single volcano in the world would actually be a more wholesale form of supervillain-esque destruction.
Thing is, there’s more ways to bring doom to the planet than people realize. So, as it’s International Water Day this week (March 22), we thought we’d bring about the end of the world by removing all of its water.
As you might expect, people would die very quickly without it, but what would happen to the rest of the planet? Would there be anything left except for a dusty shell, or would life, as they say, find a way? Let’s take a look.
The Pale Brown Dot
It’s 2017, and a gigantic fleet of alien explorers has just appeared somewhere between Earth and the Moon. They’ve been a bit silly, you see – by burning too many carbon-rich fossil fuels and pumping out far too much greenhouse gases, they’ve caused their planet’s climate to warm so much that all the water on it has evaporated.
So, they’ve turned up with a big space vacuum cleaner to steal all of ours. For the sake of simplicity, we can say that it has the power to remove water from everything except living things.
With world leaders unable to do anything about it, and the US – with all its military might – responding by Tweeting insults at the alien fleet in all caps, we’re hopeless to defeat the extraterrestrial aggressors.
The first thing we’d notice is that the rivers, lakes, ponds, puddles, and oceans would disappear. All life within them would perish within hours, and the continents we live on would suddenly tower over these newly created basins, most of which would be 3.8 kilometers (12,500 feet) deep.

The Arctic would essentially stop existing, and the hidden bathymetry beneath it would resemble a series of jagged crevasses. The Antarctic, free from its icy duvet, would become a rocky, barren land full of mountains and unfathomably large canyons.
Clouds would no longer hang over the nations of the world, rain and snow would become extinct, hurricanes and thunderstorms would evaporate away into nothingness, and our pale blue dot would be decidedly more brown and green. Weather would be dominated by wind patterns and little else. Sandy deserts would spread across the planet.
Eventually, vegetation would die out. Animal life, including us, would soon follow suit and bite the literal dust.
