Water Bodies.

           Water bodies are essential to our daily life.
About 2/3 of earth is water. They protect our earth.
They help in the ecosystem.

Why the earth in blue colour???
Because the 2/3 of earth is water. 
           
           But the pure water is very small quantity.
          Water in the sea is salty. Water in rivers and lakes are not good to                                               drink.
           Only the water in the well  is always good. 
            There are plenty of oxygen in pure water.

                                                                                                                                                   By the scarcity of drinking water some people make bore well.
Bore well is not good. It is hard water and it affect our body. 
There is many chemical substance in bore water.
There is also some way to avoid hardness.

             Please water use carefully.

Save water.
