Did you know that approximately 70% of the earth's surface is covered with water? If there is so much water, why do we still hear that there is a shortage of water, and that we're running out of water?
The answer lies in the fact that only 2-3% of this is fresh water, the rest being sea water, which contains salt and other minerals, making it undrinkable for humans.
To make matters worse, 90% of this fresh water is unavailable to us because it is in a frozen state in the North and South Poles, or too deep beneath the earth for us to reach.
More than a quarter of the world's population is without safe drinking water. Without water, there is no life. We can survive up to a month without food, but we won't last a week without water. 60% of an adult body and almost 80% of a baby is water! Even though water is constantly recycled, factors such as natural disasters and contamination are reducing the supply of fresh water, while at the same time, demand is increasing.
It is no surprise then that the UN has decreed 2005-2015 the International Decade for Action ‘Water for Life’.

The Water Cycle Song
Somewhere out there the sun is shining in a little puddle.
That's just part of something that we call: the water cycle.
Water from a little puddle turns to gas: Evaporation
The gas forms into puffy clouds: Condensation
The clouds get heavy and the rain pours down: Precipitation in their puddles on the ground
Oh, the water cycle round and round
Vapour goes up and the rain comes down
Water in the sky, in the ocean, in the ground
It's all in a cycle going round and round
Some clouds look like a horse's tail: that's cirrus (Cirrus)
Some clouds look like cauliflowers: that's cumulus (Cumulus)
Some clouds look like a blanket of grey: that's stratus (Stratus)
There are high clouds low clouds and in between clouds
Fog on the ground is also where we see clouds
(Yeah, yeah, yeah)
Oh, the water cycle round and round
Vapour goes up and the rain comes down
Water in a river, in a glass, in a cloud
It's all in a cycle going round and round
When warm air meets cold air trouble brews
That could mean a storm and that's bad news
A hurricane can form when that happens near warm water
Look out if that storm reaches land
Get out of the way; grab your sons and daughters
Crash, bash, boom and Kebam
Oh no, we forgot Uncle Dan
I'm okay, I'm allright, I was just hiding in a garbage can
(He was hiding in a garbage can)
Oh, the water cycle round and round
Vapour goes up and the rain comes down
Water in a person, in a well deep down
It's all in a cycle going round and round
