Water,like air and sunshine,is very important to living things.All animals and plants need water.tartline(1)Without water,there can be no life on earth ndline.
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 covers most parts of the earthndline.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 sea water.(3)There is too much salt in itndline.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 the 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)We are polluting the lakes and riversndline.As a result,there is not much drinking water left.
(5)So we may say ,we are now living in a thirsty world.
