Water，like air and sunshine，is very important to living things．All animals and plants need water．  1

Man also needs water．He needs it to drink，to cook and to clean himself．It even makes up the greater part of his body．

Water is almost everywhere．  2  It is in lakes，rivers and seas．Even in the driest places of the world，there is water in the air．

However，most of the water on earth is seawater．  3   So it is not good for drinking or washing．We can only drink or use fresh water．It makes up only a very small part of all tee water on earth．

To make things even worse，our need for water is growing and，at the same time．we are wasting the clean fresh water．  4   As a result，there is not much drinking water left．  5
