harry click hereto find out some fascinating facts about rivers.
Did you know that three quarters of our planet is covered in water? Most of it (almost 97%) is in the seas and oceans - and we can't drink it. Do you know why? jack
cecile Of course, it's because it's salty - did you know that?
So that means that there's only 3% we can drink then! harry
jack Not exactly, Harry. Most fresh water is frozen in icebergs and glaciers, or locked up underground in the rocks. In the end we have a very small amount to share amongst all the people in the world, less than 1%. Most of that flows in our rivers and streams.

Think of it this way Harry, if all the water of the world was placed in a one-litre bottle, only one teaspoon would be fresh water for drinking! cecile
harry That's not a lot of water to go round, is it?
I know. It's amazing that we don't run out of water! In fact, we have to re-cycle a lot of it. Just think, the water you are drinking today could have been watering fields or producing energy last week! cecile
jack But we should remember that water is a precious resource, and should not be wasted. If we ran out of water all life would come to an end. Do you remember what it was like when we had a water shortage?
I remember, we couldn't water the garden or wash the car. I did offer not to have a bath, but Mum still made me! harry
cecile My friends told me about the time they had no water. They had to go to standpipes in the road with buckets and containers to collect enough to use for the day. They soon got tired of carrying it. Luckily, the pipes were mended quickly.

Many places in the world are not as fortunate as us. In some of the drier parts of Africa, children often have to help their parents by walking many miles to collect water. Some countries in the Middle East are facing the threat of no water because neighbouring countries are building dams and cutting off the supply of water. jack

cecile So we shouldn't take water for granted! Why don't you have a go in persuading people to save water by taking part in our competition?
Look at these names, can you tell what they have in common?
